t有很多关于窗口服务器的知识，但UnauthorizedAccessException听起来像一个权限问题。我想知道，如果有人可以指出我在正确的方向，我可能需要做，给我的小应用程序访问使用单词。

Still fairly new to .NET and don't have much knowledge about window server, but "UnauthorizedAccessException" sounds like a permission issue. I'm wondering if someone could point me in the right direction on what i might need to do to give my little application access to use word.

推荐答案

这听起来像是权限问题。你在Windows服务中运行你的代码？服务通常作为本地系统运行，它可能没有访问Word对象模型的权限。此外，如果word已经使用某些其他用户的凭据运行，那么您的程序可能无法使用不同的凭据通过COM访问它。办公室应用程序往往是单一的实例，这似乎加剧了这个问题。

It definitely sounds like a permissions problem. Are you running your code in a windows service? The service normally runs as Local System, which may not have permission to access the Word object model. Additionally, if word is already running using the credentials of some other user then your program may not be able to access it via COM using different credentials. The office applications tend to be single instance which seems to exacerbate this problem.
