Unable to generate a temporary class (result=1).error CS2001: Source file 'C:\WINDOWS\TEMP\ug5v9uxt.0.cs' could not be found

System.InvalidOperationException: Unable to generate a temporary class (result=1).
error CS2001: Source file 'C:\WINDOWS\TEMP\ug5v9uxt.0.cs' could not be found

解决方法：给C:\WINDOWS\TEMP目录赋予asp.net用户完全控制的权限。

asp.net用户 一般是叫 IIS_WPG
