IronPPT 是一个强大的 PowerPoint 库，旨在帮助 .NET C# 开发人员将创建、读取和编辑 PowerPoint 演示文稿的功能无缝集成到他们的应用程序中。在 PowerPoint 演示文稿中，幻灯片是构建和组织内容的基础元素。

快速入门：在新幻灯片或现有幻灯片中插入文本

这个例子展示了使用 IronPPT 如何轻松地向幻灯片添加文本。只需几行代码，即可将其插入到第一张幻灯片中（如果存在），或者创建一个新幻灯片，然后保存——设置快速，操作简便。

使用 NuGet 包管理器安装 IronPPT
PM > Install-Package IronPPT

复制并运行这段代码。

var doc = new IronPPT.PresentationDocument();
var text = doc.Slides.Count > 0 ? doc.Slides[0].AddText("Quick Option") : doc.Slides.Add(new IronPPT.Models.Slide()).AddText("Quick Option");
doc.Save("quick.pptx");

添加文本

文本内容

无论您是创建新的演示文稿还是编辑现有的演示文稿，文本管理工具都能让您完全控制文本的位置和格式，从而设计出清晰、专业地传达信息的幻灯片。

using IronPPT.Models;

// Create a new PowerPoint presentation
var document = new PresentationDocument();

// Ensure there is at least one slide to work with
if (document.Slides.Count == 0)
{

}

// Add text to the first slide
var text = document.Slides[0].AddText("Hello");

// Append text to the existing text on the slide

设置样式

文本样式允许您通过定义字体大小、颜色、样式、删除线和下划线等属性来自定义文本的视觉外观。应用这些样式可以增强文本的呈现效果，并改善文档的整体外观。

:path=/static-assets/ppt/content-code-examples/tutorials/slide-element-text-style.cs

using IronPPT;
using IronPPT.Models; // Ensure the library is available

// Create a new presentation document
var document = new PresentationDocument();

// Define and customize the text style
var textStyle = new TextStyle
{
    IsBold = true,                      // Text is bold
    IsItalic = true,                    // Text is italic
    Color = Color.Blue,                 // Text color is blue
    Strike = StrikeValue.SingleStrike,  // Text is single struck-off
    Outline = true,                     // Text has an outline
    NoProof = true,                     // Disables proofing for the text
    Spacing = 10.0,                     // Text spacing is set to 10
    Underline = new Underline 
    {
        LineValue = UnderlineValues.Single,   // Single underline
        Color = Color.Red                     // Underline color is red
    },
    Languages = "en-US",               // Text language is set to U.S. English
    SpecVanish = false,                // Text does not vanish when special formatting is applied
};

// Create text content and apply the defined style
var text = new Text("Hello World");   // Instantiate text with a string
text.TextStyle = textStyle;           // Apply the defined style to the text

// Add a new slide if none exist
if (document.Slides.Count == 0)
{
    document.Slides.Add(new Slide());   // Add a new slide to the document
}

// Add the styled text to the first slide
document.Slides[0].AddText(text);      // Add the newly created text object to the first slide

// Save the presentation document to a file
document.Save("textStyle.pptx");        // Save the document with the filename "textStyle.pptx"

添加图片

调整图像设置以获得最佳显示效果。正确的配置可确保图像在视觉上吸引人，并与其上下文相符。

using IronPPT;
using IronPPT.Models;
using System.Drawing;

// This script demonstrates the creation of a PowerPoint presentation using the IronPPT library.
// An image is added to the presentation, its properties are modified, and then the presentation is saved.

// Create a new PowerPoint presentation
var document = new PresentationDocument();

// Create a new Image object and load an image file.
var image = new Image();
image.LoadFromFile("sample.png");

// Add the image to the first slide (index 0) of the presentation.
var newImage = document.AddImage(image, 0);

// Set the properties of the added image.
// Position property is set using a Point object, which holds X and Y coordinates.
newImage.Position = new Point(200, 200); // Set image position on the slide
newImage.Angle = 45; // Set the rotation angle of the image
newImage.Name = "new image"; // Assign a descriptive name to the image
newImage.Width = 150; // Set the width of the image in pixels
newImage.Height = 150; // Set the height of the image in pixels

// Export the PowerPoint presentation to a file named "addImage.pptx"
document.Save("addImage.pptx");

添加形状

通过定义形状的类型、尺寸（宽度和高度）、填充和轮廓颜色以及在幻灯片上的位置，可以轻松地在演示文稿中添加和自定义形状。

:path=/static-assets/ppt/content-code-examples/tutorials/slide-element-add-shape.cs

using IronPPT;
using IronPPT.Models;
using IronPPT.Enums;

// Load a PowerPoint presentation.
// The PresentationDocument is assumed to represent an entire PPTX file loaded from disk.
var document = new PresentationDocument("output.pptx");

// Configure a new shape.
// Shape is assumed to be a model object representing drawable elements on a slide.
Shape shape = new Shape
{
    Name = "triangle",
    Type = ShapeType.Triangle,
    Width = 100,
    FillColor = new Color("#444444"),
    OutlineColor = Color.Black,

    // Position is set via assumed X and Y positioning properties.
    // It's important that these properties are set to valid coordinates for display on the slide.
    XPosition = 200,
    YPosition = 200
};

// Add the shape to the first slide in the presentation.
// Slides[0] refers to the first slide in the collection. Ensure a slide exists at this index.
document.Slides[0].AddShape(shape);

// Export the modified PowerPoint presentation.
// Saves the changes to a new file, ensuring the original presentation is not overwritten.
document.Save("addShape.pptx");
