如何保存的* .ppt，* .PPTX文件，* .WMV使用互操作使用C＃？ [英] How to save *.ppt, *.pptx files as *.wmv using Interop with C#?

问题描述

我想下一个code做到这一点：

I tried to do this with the next code:

using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using System.IO;
using Microsoft.Office.Interop.PowerPoint;

namespace SavePPT
{
        class Program
        {
            static void Main(string[] args)
            {
                Application app = new PowerPoint.Application();
                var pres = app.Presentations;
                var file = pres.Open(@"C:\Presentation1.pptx", MsoTriState.msoTrue, MsoTriState.msoTrue, MsoTriState.msoFalse);
                file.SaveCopyAs(@"C:\presentation1.wmv", PowerPoint.PpSaveAsFileType.ppSaveAsWMV, MsoTriState.msoCTrue);

                app.Quit();

            }
        }
}

不过，当然这种解决方案创建的0 KB大小的文件，我不能玩。

But this solution created file with 0 KB size and of course I can't play it.

推荐答案

PowerPoint的SaveCopyAs方法似乎并不支持ppSaveAsWMV。它明确指出，它支持在<一个href="http://msdn.microsoft.com/en-us/library/microsoft.office.interop.powerpoint._$p$psentation.savecopyas.aspx"相对=nofollow> MSDN页 SaveCopyAs，其中不包括ppSaveAsWMV不变。

PowerPoint's SaveCopyAs method doesn't appear to support ppSaveAsWMV. It explicitly states which it supports on the MSDN page for SaveCopyAs, which doesn't include the ppSaveAsWMV constant.
