Process调用DOS相关问题

[dongshanyu]

想通过Process调用DOS命令连接目标机器上的共享文件夹，代码如下:

       Dim objProc As New System.Diagnostics.Process
        Try
            objProc.StartInfo.FileName = "CMD.EXE"
            objProc.StartInfo.UseShellExecute = False
            objProc.StartInfo.RedirectStandardInput = True
            objProc.StartInfo.RedirectStandardOutput = True
            objProc.StartInfo.RedirectStandardError = True
            objProc.StartInfo.CreateNoWindow = True
            objProc.Start()
            Dim strCmd As String = String.Empty
            'strCmd = String.Format("NET USE {0} ""{1}"" /USER:""{2}"" ", strDir, strPWD, strUser)
            strCmd = String.Format("NET USE {0} ""{1} /USER:{2}"" ", strDir strPWD, strUser)
            objProc.StandardInput.WriteLine(strCmd)
            objProc.StandardInput.WriteLine("EXIT")
            While Not objProc.HasExited
                objProc.WaitForExit(1000)
            End While
            Dim strErrorMsg As String = objProc.StandardError.ReadToEnd
            objProc.StandardError.Close()
            If strErrorMsg Is Nothing Or strErrorMsg = String.Empty Then
            Else
                Throw New Exception(strErrorMsg)
            End If
        Catch ex As Exception
            Return False
        Finally
            objProc.Close()
            objProc.Dispose()
        End Try

但连接失败，系统提示:
System error 1326 has occurred.
Logon failure: unknown user name or bad password.

但若通过手工cmd窗口，执行上面的 NET USE，连接没问题。
有谁知道问题在哪？

确认下 strCmd = String.Format("NET USE {0} ""{1} /USER:{2}"" ", strDir strPWD, strUser) 这个产生出来的字串是否正确。

用WNetAddConnection2登录

直接使用net.exe

调试的时候看看信息跟你CMD里用的一样不

通过Process调用Cmd执行Dos命令时，用户名未指明目标机器： 修正前:test 修正后:machine\test 未指明目标机器有时也能成功建立连接，测试时我连接另外一台目标机器时就遇到此情况，第1次连接会成功，之后会一直提示: System error 1312 has occurred. A specified logon session does not exist. It may already have been terminated. 只是有些疑惑，为何手工打开cmd，输入用户名未指明目标机器，没有这个问题。
