推荐答案

为该文件提供ASPNET完全访问权限.或使用模拟访问它.

Provide ASPNET full access to that file. Or use impersonation in order to access it.

有两句话要说:

There are two things to say:

1. 是一种很好的编程技术，可以将可能引发异常的每个代码块包装在try/catch块中并处理错误情况；这将防止您的应用程序异常终止
2. ，您将收到该异常，因为您的应用程序没有访问所需文件/文件夹所需的权限；如果您在Windows Vista或7上运行该应用程序，则需要处理 UAC 并以 administrator 身份运行您的应用程序.另一种方法是将文件移动到当前用户文件夹

1. is a good programming tecnique to wrap each block of code that could throw an exception in a try/catch block and handle the error condition; this will prevent your application to abnormally terminate
2. you are getting that exception because your application has not the rights required to access the file/folder that you want; If you are running the application on Windows Vista or 7 you need to deal with the UAC and run your application as administrator. Another way could be to move your file to another folder, inside the current user folder
