如何在 ASP.NET MVC 中读取 PPT 文件？

我的桌面上有一个名为“slide.ppt”的 PPT 文件。我想在我的文件夹中阅读该 PPT 文件的所有幻灯片ReadSlide功能如下

public void ReadSlide(){


}

如何使用 C# 代码读取 PPT 文件中的所有幻灯片？

使用如下

public void ReadSlide(){

            string filePath= @"C:\Users\UserName\Slide.pptx";

            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(filePath, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);

            string presentation_textforParent = "";
            foreach (var item in presentation.Slides[1].Shapes)
            {
                var shape = (Microsoft.Office.Interop.PowerPoint.Shape)item;
                if (shape.HasTextFrame == MsoTriState.msoTrue)
                {
                    if (shape.TextFrame.HasText == MsoTriState.msoTrue)
                    {
                        var textRange = shape.TextFrame.TextRange;
                        var text = textRange.Text;

                        presentation_textforParent += text + " ";
                    }
                }
            }
}
