I write a program accessing files in network drive o:. It is doable as a standalone application. However, if it is running under windows service, the following exception will appear:

13/07/2004 10:24:48 AM run() error: System.IO.IOException: The specified network password is not correct.

   at System.IO.__Error.WinIOError(Int32 errorCode, String str)
   at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath, Boolean bFromProxy)
   at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share)
   at dump_tool.Dump_Load.run()


The source codes relevant are:

Cur_Fs = File.Open( Cur_File, FileMode.Open, FileAccess.Read, FileShare.Read );

Where Cur_File = "o:\jul04\10\fares.fl", o: is a mapped network drive.

"o:\jul04\10\fares.fl" 路径前面最好加上@避免出现转义如
Cur_File =@"o:\jul04\10\fares.fl";

在接受路径作为输入字符串的成员中，路径的格式必须正确，否则将引发异常。例如，如果路径是完全限定的但以空格开头，则路径在类的方法中不会被修剪。因此，路径的格式不正确，并将引发异常。同样，路径或路径的组合不能被完全限定两次。例如，“c:\temp c:\windows”在大多数情况下也将引发异常。在使用接受路径字符串的方法时，请确保路径的格式正确。

确保对那个驱动器的文件有访问权限
