对于 .NET 来说还是个新手，对窗口服务器了解不多，但UnauthorizedAccessException"听起来像是权限问题.我想知道是否有人可以指出我可能需要做些什么来让我的小应用程序访问使用 word 的正确方向.

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

听起来绝对是权限问题.您是否在 Windows 服务中运行代码?该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.办公应用程序往往是单一实例，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.
