使用 C# 编辑 Sharepoint 服务器上的文件 [英] Editing a file on a Sharepoint Server with C#

问题描述

我正在尝试通过 C# 在 Sharepoint 上编辑 PowerPoint 文件.我可以直接访问该目录，所以我尝试这样做，就像我在本地系统上编辑 PPT 文件一样:

I am trying to edit a PowerPoint file on a Sharepoint through C#. I have direct access to the directory so I tried doing it like I would if I where to edit a PPT file on my local system:

// Open Presentation
pptPresentation = pptApplication.Presentations.Open(@"\\sharepoint.adress.com@SSL\UserWWWRoot\folder\subfolder\Pres.pptx");

// Open slide on which ID has to be added.
pptSlide = pptPresentation.Slides[slideNumber];

// Add Textbox
shape = pptSlide.Shapes.AddTextbox(MsoTextOrientation.msoTextOrientationHorizontal, 0, 0, 1, 1);

[...]

但我总是在第一行代码中收到拒绝访问"错误，即使我已登录并在另一个窗口中打开该文件夹也是如此.我是否必须以任何特殊方式打开文件，因为它位于 Sharepoint 上?有没有更好的方法来做到这一点?

But I always get a "Access Denied" error on the first line of code, even if I am logged in and have the folder open in another window. Do I have to open the file in any special way because it's on a Sharepoint? Is there a better approach to doing this?

有效的是将文件复制到我的本地目录，然后打开编辑并将其复制回来.但出于多种原因，我不允许这样做.

What worked was copying the file to my local directory and then opening editing it and copying it back. But I am not allowed to do that for multiple reasons.
