如何在.net 中执行console命令Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load        '创建一个新的进程对象
        Dim myCmdProcess As New Process
        '注册进程退出事件
        'myCmdProcess.Exited += New System.EventHandler(myCmdProcess_exited)
        AddHandler myCmdProcess.Exited, AddressOf myCmdProcess_exited
         myCmdProcess.StartInfo.FileName = "cmd"       '要执行的命令
        '将参数传给要调用的应用程序 /C 执行字符串指定的命令然后终断 ,调用dir,同时将结果输出到应用程序文件夹下test.txt.
        myCmdProcess.StartInfo.Arguments = "/C  dir >test.txt"
        myCmdProcess.StartInfo.RedirectStandardOutput = True
        myCmdProcess.StartInfo.UseShellExecute = False
        myCmdProcess.StartInfo.CreateNoWindow = True
        myCmdProcess.EnableRaisingEvents = True
        myCmdProcess.Start()
        Console.Read()
    End Sub '进程退出时调用的方法Private Sub myCmdProcess_exited(ByVal sender As Object, ByVal e As System.EventArgs)
        Try
            Dim myFile As System.IO.StreamReader = New System.IO.StreamReader("test.txt")
            Dim myString As String = myFile.ReadToEnd()
            myFile.Close()
            MessageBox.Show(myString)
        Catch ex As Exception
