c# - 从 Powerpoint 演示文稿的幻灯片中读取/写入 html

Question

是否可以在 C# 中获取 PPT 的幻灯片 html。

以及如何在使用互操作创建演示文稿的同时使用 html 创建新幻灯片？

Answer 1

您可以从 PPT 文件中读取并从每张幻灯片中获取文本，请参见下面的示例：

static void Main(string[] args)
        {
            Microsoft.Office.Interop.PowerPoint.Application PowerPoint_App = new Microsoft.Office.Interop.PowerPoint.Application();
            Microsoft.Office.Interop.PowerPoint.Presentations multi_presentations = PowerPoint_App.Presentations;
            Microsoft.Office.Interop.PowerPoint.Presentation presentation = multi_presentations.Open(@"C:\PPT\myPowerpoint.pptx");
            string presentation_text = "";
            for (int i = 0; i < presentation.Slides.Count; i++)
            {
                foreach (var item in presentation.Slides[i+1].Shapes)
                {
                    var shape = (PowerPoint.Shape)item;
                    if (shape.HasTextFrame == MsoTriState.msoTrue)
                    {
                        if (shape.TextFrame.HasText == MsoTriState.msoTrue)
                        {
                            var textRange = shape.TextFrame.TextRange;
                            var text = textRange.Text;
                            presentation_text += text+" ";
                        }
                    }
                }
            }
            PowerPoint_App.Quit();
            Console.WriteLine(presentation_text);
        }
