如何為DOCX新增文字樣式？

在IronWord中應用文字樣式需要使用Run包裝模式。建立一個TextContent。使用例如TextContent）。

樣式設定完成後，使用Paragraph中，將段落插入文件中，並保存結果。此方法為自動化文件生產場景提供了一致樣式所需的程式化文字格式控制。

請注意: IronWord的文件層次結構遵循結構：Document → DocumentSection → Paragraph → Run → TextContent。樣式應用於TextContent。

using IronWord;
using IronWord.Models;
using IronWord.Models.Enums;

// Load docx
WordDocument doc = new WordDocument("sample.docx");

// Configure text
Run textRun = new Run(new TextContent("Add text using IronWord"));

// Configure text style settings
textRun.Style = new TextStyle()
{
    FontSize = 24, // Text Size is 24
    TextFont = new Font()
    {
        FontFamily = "Calibri" // Text Font is "Calibri"
    },
    Color = Color.Red, // Set text color to red
    IsBold = true,     // Make text bold
    IsItalic = true,   // Make text italic
    Underline = new Underline(), // Have an underline
    Strike = StrikeValue.DoubleStrike, // Double strike-through
};

Paragraph paragraph = new Paragraph();

// Add text to paragraph
paragraph.AddChild(textRun);

// Add paragraph to document
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("add-text-style.docx");

using IronWord;
using IronWord.Models;
using IronWord.Models.Enums;

// Load docx
WordDocument doc = new WordDocument("sample.docx");

// Configure text
Run textRun = new Run(new TextContent("Add text using IronWord"));

// Configure text style settings
textRun.Style = new TextStyle()
{
    FontSize = 24, // Text Size is 24
    TextFont = new Font()
    {
        FontFamily = "Calibri" // Text Font is "Calibri"
    },
    Color = Color.Red, // Set text color to red
    IsBold = true,     // Make text bold
    IsItalic = true,   // Make text italic
    Underline = new Underline(), // Have an underline
    Strike = StrikeValue.DoubleStrike, // Double strike-through
};

Paragraph paragraph = new Paragraph();

// Add text to paragraph
paragraph.AddChild(textRun);

// Add paragraph to document
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("add-text-style.docx");

這會生成什麼輸出？

Microsoft Word介面顯示"版面配置"功能區和應用紅色刪除線文字格式的文件。

TextFont屬性內設定。 TextContent並保持樣式，遵循IronWord的文件層次結構模式。這個範例演示了如何將多種樣式屬性結合應用於Run以建立豐富格式的文字。

我可以新增哪些特定樣式？

如何更改文字顏色？

IronWord.Models.Color中的預定義顏色或自訂的十六進位值。這強調了特定內容或匹配品牌顏色。 IronWord支持多種顏色，包括紅色、藍色、綠色、橄欖色、海軍藍和栗色。

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add colored text
Run textRun = new Run(new TextContent("This text is olive-colored!"));
textRun.Style = new TextStyle()
{
    Color = IronWord.Models.Color.Olive // defining text to be colored olive
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("colored-text.docx");

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add colored text
Run textRun = new Run(new TextContent("This text is olive-colored!"));
textRun.Style = new TextStyle()
{
    Color = IronWord.Models.Color.Olive // defining text to be colored olive
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("colored-text.docx");

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add colored text
Dim textRun As New Run(New TextContent("This text is olive-colored!"))
textRun.Style = New TextStyle() With {
    .Color = IronWord.Models.Color.Olive ' defining text to be colored olive
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("colored-text.docx")

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add colored text
Dim textRun As New Run(New TextContent("This text is olive-colored!"))
textRun.Style = New TextStyle() With {
    .Color = IronWord.Models.Color.Olive ' defining text to be colored olive
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("colored-text.docx")

有色文字看起來如何？

Microsoft Word顯示橄欖色色調文字格式，首頁標籤功能區中顯示字體和段落工具。

如何設置字體系列和大小？

使用TextFont屬性自訂文字外觀。將FontFamily設置為任何已安裝的字體名稱（例如，"Arial"，"Times New Roman"）和點數的FontSize。這建立了視覺層次結構，並確保在不同裝置和平台上的可讀性。

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add text with custom font family and size
Run textRun = new Run(new TextContent("This text uses Arial at 24pt!"));
textRun.Style = new TextStyle()
{
    FontSize = 24,  // Set font size in points
    TextFont = new IronWord.Models.Font()
    {
        FontFamily = "Arial"  // Set font family
    }
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("font-styled-text.docx");

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add text with custom font family and size
Run textRun = new Run(new TextContent("This text uses Arial at 24pt!"));
textRun.Style = new TextStyle()
{
    FontSize = 24,  // Set font size in points
    TextFont = new IronWord.Models.Font()
    {
        FontFamily = "Arial"  // Set font family
    }
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("font-styled-text.docx");

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add text with custom font family and size
Dim textRun As New Run(New TextContent("This text uses Arial at 24pt!"))
textRun.Style = New TextStyle() With {
    .FontSize = 24,  ' Set font size in points
    .TextFont = New IronWord.Models.Font() With {
        .FontFamily = "Arial"  ' Set font family
    }
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("font-styled-text.docx")

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add text with custom font family and size
Dim textRun As New Run(New TextContent("This text uses Arial at 24pt!"))
textRun.Style = New TextStyle() With {
    .FontSize = 24,  ' Set font size in points
    .TextFont = New IronWord.Models.Font() With {
        .FontFamily = "Arial"  ' Set font family
    }
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("font-styled-text.docx")

自訂字體樣式如何顯示？

Microsoft Word顯示工具欄中選擇24pt的Arial字體，帶有格式化的範例文字。

如何使文字加粗？

將Bold。 Bold文字常用於標題、強調或突出重要資訊。結合其他樣式屬性，Bold文字建立視覺層次結構，並提高可讀性。

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add bold text
Run textRun = new Run(new TextContent("this is bold!"));
textRun.Style = new TextStyle()
{
    IsBold = true  // Make text bold
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("bold-text.docx");

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add bold text
Run textRun = new Run(new TextContent("this is bold!"));
textRun.Style = new TextStyle()
{
    IsBold = true  // Make text bold
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("bold-text.docx");

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add bold text
Dim textRun As New Run(New TextContent("this is bold!"))
textRun.Style = New TextStyle() With {
    .IsBold = True ' Make text bold
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("bold-text.docx")

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add bold text
Dim textRun As New Run(New TextContent("this is bold!"))
textRun.Style = New TextStyle() With {
    .IsBold = True ' Make text bold
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("bold-text.docx")

粗體文字怎麼看？

Microsoft Word介面顯示粗體文字格式，"this is bold!"文字顯示在文件中。

如何使文字斜體？

將Italic樣式。 Italic文字通常用於強調、標題、外文或技術詞彙。這種微妙的格式將文字元素區分開來，而不會像Bold格式那樣具視覺負擔。

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add italic text
Run textRun = new Run(new TextContent("this is italic."));
textRun.Style = new TextStyle()
{
    IsItalic = true  // Make text italic
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("italic-text.docx");

using IronWord;
using IronWord.Models;

// Create document
WordDocument doc = new WordDocument();

// Add italic text
Run textRun = new Run(new TextContent("this is italic."));
textRun.Style = new TextStyle()
{
    IsItalic = true  // Make text italic
};

Paragraph paragraph = new Paragraph();
paragraph.AddChild(textRun);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("italic-text.docx");

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add italic text
Dim textRun As New Run(New TextContent("this is italic."))
textRun.Style = New TextStyle() With {
    .IsItalic = True  ' Make text italic
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("italic-text.docx")

Imports IronWord
Imports IronWord.Models

' Create document
Dim doc As New WordDocument()

' Add italic text
Dim textRun As New Run(New TextContent("this is italic."))
textRun.Style = New TextStyle() With {
    .IsItalic = True  ' Make text italic
}

Dim paragraph As New Paragraph()
paragraph.AddChild(textRun)
doc.AddParagraph(paragraph)

' Save document
doc.SaveAs("italic-text.docx")

斜體文字怎樣看？

有哪些可用的樣式屬性？

IronWord提供了全面的樣式屬性，鏡像Microsoft Word的格式選項。這些屬性結合起來，建立符合專業文件標準的複雜文字格式。

樣式方法	描述	範例
`TextFont`	使用`Font`物件自訂文字外觀，設定字體系列。注意：`FontSize`在`TextStyle`層次設置，而不是在`Font`內。	`textRun.Style = new TextStyle() { FontSize = 24, TextFont = new Font() { FontFamily = "Calibri" } };`
`Color`	使用IronWord.Models.Color中的預定義顏色或自訂的十六進位值設定文字顏色。	`textRun.Style.Color = IronWord.Models.Color.Red;`
`IsBold`	將文字設為`Bold`當設置為`true`時，通常用於標題或強調。	`textRun.Style.IsBold = true;`
`IsItalic`	當設置為`true`時，給文字應用`Italic`樣式，通常用於強調或標題。	`textRun.Style.IsItalic = true;`
`Underline`	使用強調的`Underline`物件為文字新增底線，具有各種下劃線樣式。	`textRun.Style.Underline = new Underline();`
`Strike`	透過使用`StrikeValue`枚舉應用刪除線（`Strike`或`DoubleStrike`）設定文字刪除線。	`textRun.Style.Strike = StrikeValue.Strike;`
`Caps`	應用大寫效果到文字，將所有字元轉換為大寫顯示。	`textRun.Style.Caps = true;`
`CharacterScale`	調整字元的比例寬度，作為其正常大小的百分比。	`textRun.Style.CharacterScale = 150;`
`Emboss`	為文字應用浮雕效果，創造出凸起的外觀。	`textRun.Style.Emboss = true;`
`Emphasis`	透過使用`EmphasisMarkValues`枚舉值，向已樣式的文字新增強調標記。	`textRun.Style.Emphasis = EmphasisMarkValues.Dot;`
`LineSpacing`	使用`LineSpacing`物件控制行文字之間的間距以提高可讀性。	`textRun.Style.LineSpacing = new LineSpacing() { Value = 1.5 };`
`Outline`	將文字渲染為帶有外框效果，僅顯示字元邊界。	`textRun.Style.Outline = true;`
`Shading`	使用強調的`Shading`物件將背景色或底紋應用於文字。	`textRun.Style.Shading = new Shading() { Color = Color.Yellow };`
`SmallCaps`	將小寫字母轉換為小型大寫字母，同時維持大小寫區別。	`textRun.Style.SmallCaps = true;`
`VerticalPosition`	調整文字相對於基線的垂直位置，以點為單位測量。	`textRun.Style.VerticalPosition = 5.0;`
`VerticalTextAlignment`	使用強調的`VerticalPositionValues`枚舉在其容器中垂直定位文字。	`textRun.Style.VerticalTextAlignment = VerticalPositionValues.Superscript;`

結合多種樣式

IronWord的文字樣式功能來源於結合多種屬性來實現複雜的格式化。這是一個範例，展示了通過結合各種樣式屬性實現的專業樣式文字：

using IronWord;

headerRun.Style = new TextStyle()
{
    FontSize = 28,
    TextFont = new Font()
    {
        FontFamily = "Georgia"
    },
    Color = Color.DarkBlue,
    IsBold = true,
    SmallCaps = true,
    Underline = new Underline(),
    CharacterScale = 110,  // Slightly expand character width
    Shading = new Shading()
    {
        Color = Color.LightGray  // Light background
    }
};

// Add header to document using AddChild for styled Run
Paragraph headerParagraph = new Paragraph();
headerParagraph.AddChild(headerRun);
doc.AddParagraph(headerParagraph);

// Create body text with different styling
Run bodyRun = new Run(new TextContent("This is professionally formatted body text with custom styling."));
bodyRun.Style = new TextStyle()
{
    FontSize = 11,
    TextFont = new Font()
    {
        FontFamily = "Calibri"
    },
    Color = Color.Black
};

Paragraph bodyParagraph = new Paragraph();

headerRun.Style = new TextStyle()
{
    FontSize = 28,
    TextFont = new Font()
    {
        FontFamily = "Georgia"
    },
    Color = Color.DarkBlue,
    IsBold = true,
    SmallCaps = true,
    Underline = new Underline(),
    CharacterScale = 110,  // Slightly expand character width
    Shading = new Shading()
    {
        Color = Color.LightGray  // Light background
    }
};

// Add header to document using AddChild for styled Run
Paragraph headerParagraph = new Paragraph();
headerParagraph.AddChild(headerRun);
doc.AddParagraph(headerParagraph);

// Create body text with different styling
Run bodyRun = new Run(new TextContent("This is professionally formatted body text with custom styling."));
bodyRun.Style = new TextStyle()
{
    FontSize = 11,
    TextFont = new Font()
