`PowerPoint` .NET 组件

using IronPPT;

// Initialize a new presentation
var ppt = new PresentationDocument();

// Add Text to the new presentation
// TextBoxes[0] typically represents the title placeholder
ppt.Slides[0].TextBoxes[0].AddText("Welcome to IronPPT");

// TextBoxes[1] typically represents the subtitle or content area
ppt.Slides[0].TextBoxes[1].AddText("This slide was generated using IronPPT!");

// Save the presentation with a descriptive filename
ppt.Save("new_presentation.pptx");

using IronPPT;

// Initialize a new presentation
var ppt = new PresentationDocument();

// Add Text to the new presentation
// TextBoxes[0] typically represents the title placeholder
ppt.Slides[0].TextBoxes[0].AddText("Welcome to IronPPT");

// TextBoxes[1] typically represents the subtitle or content area
ppt.Slides[0].TextBoxes[1].AddText("This slide was generated using IronPPT!");

// Save the presentation with a descriptive filename
ppt.Save("new_presentation.pptx");

这个例子展示了创建演示文稿的基本模式。 请注意 API 如何使用熟悉的索引来访问幻灯片和文本框。 当您实例化一个新的PresentationDocument时，会自动创建第一张幻灯片（索引 0）。 每张幻灯片都包含根据其布局预定义的文本框，您可以在其中填充内容。

输出

IronPPT库主页展示了一个实用的C#代码示例，演示了如何使用.NET API创建PowerPoint演示文稿、添加幻灯片和保存文档。

using IronPPT;

// Load the existing pptx file
// The constructor accepts a file path to an existing presentation
var ppt = new PresentationDocument("new_presentation.pptx");

// Edit the existing text by accessing the Texts collection
// Texts[0] refers to the first text element in the text box
ppt.Slides[0].TextBoxes[0].Texts[0].Text = "Hello World!";

// Save the changes to a new file to preserve the original
ppt.Save("updated.pptx");

using IronPPT;

// Load the existing pptx file
// The constructor accepts a file path to an existing presentation
var ppt = new PresentationDocument("new_presentation.pptx");

// Edit the existing text by accessing the Texts collection
// Texts[0] refers to the first text element in the text box
ppt.Slides[0].TextBoxes[0].Texts[0].Text = "Hello World!";

// Save the changes to a new file to preserve the original
ppt.Save("updated.pptx");

编辑现有演示文稿时，IronPPT 会保留所有格式和未修改的内容。 本示例演示如何加载演示文稿、修改特定文本元素并保存更改。 文本集合提供了对文本框中单个文本段的访问，从而可以精确控制内容更新。

输出

这是一个使用 IronPPT .NET 组件以编程方式创建的 PowerPoint 演示文稿示例，展示了该库生成带有格式化文本内容的幻灯片的功能。

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var ppt = new PresentationDocument("updated.pptx");

// Create a new Image object
Image img = new Image();

// Load image from file - supports common formats (JPG, PNG, etc.)
img.LoadFromFile("IronPPT.png");

// Add the image to the presentation on slide 0
// The method returns a reference to the added image for further manipulation
var newImg = ppt.AddImage(img, 0);

// Position the image using coordinates (left, top)
newImg.Position = (150, 50);

// Set dimensions - maintain aspect ratio manually if needed
newImg.Width = 400;
newImg.Height = 150;

// Save the presentation with the embedded image
ppt.Save("image.pptx");

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var ppt = new PresentationDocument("updated.pptx");

// Create a new Image object
Image img = new Image();

// Load image from file - supports common formats (JPG, PNG, etc.)
img.LoadFromFile("IronPPT.png");

// Add the image to the presentation on slide 0
// The method returns a reference to the added image for further manipulation
var newImg = ppt.AddImage(img, 0);

// Position the image using coordinates (left, top)
newImg.Position = (150, 50);

// Set dimensions - maintain aspect ratio manually if needed
newImg.Width = 400;
newImg.Height = 150;

// Save the presentation with the embedded image
ppt.Save("image.pptx");

此示例展示了 IronPPT 的图像处理功能。 Image 类提供了从各种来源加载图像的方法，定位系统使用标准的PowerPoint单位。 设置位置和大小时，请记住考虑目标幻灯片的尺寸，以确保图像在不同的显示场景中正确显示。

输出

！此编辑后的演示文稿文件显示了使用 IronPPT .NET 组件以编程方式创建 PowerPoint 幻灯片的结果。

首先，让我们使用以下代码示例向演示文稿添加幻灯片：

using IronPPT;
using IronPPT.Models;

// Load the existing presentation
var ppt = new PresentationDocument("updated.pptx");

// Create a new slide object
Slide slide = new Slide();

// Add text to the new slide
// This creates a simple slide with a title
slide.AddText("Slide Two");

// Add the slide to the presentation
// The slide is appended to the end of the presentation
ppt.AddSlide(slide);

// Create another slide for demonstration
Slide slide3 = new Slide();
slide3.AddText("Slide Three");
ppt.AddSlide(slide3);

// Save the updated presentation
ppt.Save("updated.pptx");

using IronPPT;
using IronPPT.Models;

// Load the existing presentation
var ppt = new PresentationDocument("updated.pptx");

// Create a new slide object
Slide slide = new Slide();

// Add text to the new slide
// This creates a simple slide with a title
slide.AddText("Slide Two");

// Add the slide to the presentation
// The slide is appended to the end of the presentation
ppt.AddSlide(slide);

// Create another slide for demonstration
Slide slide3 = new Slide();
slide3.AddText("Slide Three");
ppt.AddSlide(slide3);

// Save the updated presentation
ppt.Save("updated.pptx");

添加幻灯片时，IronPPT 会自动处理内部演示文稿结构。 除非另有指定AddSlide否则每个新幻灯片都会使用默认布局。AddSlide 方法会将幻灯片添加到演示文稿的末尾，但正如我们接下来将看到的，您可以轻松地重新排列它们。

输出

现在我们的演示文稿包含多张幻灯片，我们可以轻松地重新排序：

using IronPPT;

// Configure your license key to remove trial limitations
IronPPT.License.LicenseKey = "YOUR-LICENSE-KEY";

// Load the presentation with multiple slides
var ppt = new PresentationDocument("updated.pptx");

// Reorder slides by changing their Index property
// This moves the third slide (index 2) to the second position (index 1)
ppt.Slides[2].Index = 1;

// The library automatically adjusts other slide indices
// Original order: [0, 1, 2] -> New order: [0, 2, 1]

// Save the reordered presentation
ppt.Save("updated.pptx");

using IronPPT;

// Configure your license key to remove trial limitations
IronPPT.License.LicenseKey = "YOUR-LICENSE-KEY";

// Load the presentation with multiple slides
var ppt = new PresentationDocument("updated.pptx");

// Reorder slides by changing their Index property
// This moves the third slide (index 2) to the second position (index 1)
ppt.Slides[2].Index = 1;

// The library automatically adjusts other slide indices
// Original order: [0, 1, 2] -> New order: [0, 2, 1]

// Save the reordered presentation
ppt.Save("updated.pptx");

在动态构建演示文稿时，幻灯片重新排序功能尤其有用。 您可以按照幻灯片生成的顺序添加它们，然后根据业务逻辑或用户偏好重新排序。 Index 属性使这个过程直观高效。

输出

现在，带有"幻灯片二"字样的幻灯片已重新排列到正确的位置，成为我们演示文稿中的第二张幻灯片。
