当我打开word文档并将其保存在我的机器上时，它工作正常，但是当我将它上传到服务器上并在那里打开它时，它会if (doc == null)阻塞，它不应该去。

如果它不相关，请更新我的问题标题或要求任何澄清。

这是我的课：

为您的 ASP.NET 用户创建一个桌面文件夹可能已经解决了一个问题，但您会遇到更多问题。Word可能会弹出一个对话框，你会被卡住。

服务器端明确不支持办公自动化，相信我 - 你会有很多问题：

Microsoft 目前不推荐也不支持任何无人值守、非交互式客户端应用程序或组件（包括 ASP、ASP.NET、DCOM 和 NT 服务）的 Microsoft Office 应用程序自动化，因为 Office 可能表现出不稳定的行为和/或在此环境中运行 Office 时出现死锁。

我建议您仔细阅读上面链接中引用的文章，并使用替代方案。

好的问题解决了感谢Sameer S的帖子Desktop我刚刚在服务器2008机器上 创建文件夹@

C:\Windows\System32\config\systemprofile

现在它的工作

除此之外，因为这是ASP.NET应用程序，所以我impersonation在调用类之前添加了检查，它工作正常。
