如何在vb.net的异步BackgroundWorker进程中运行cmd行实用程序？

例子：

Private Sub UpgradeButton_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpgradeButton.Click 
    BackgroundWorker1.RunWorkerAsync() 
End Sub 

Private Sub BackgroundWorker1_DoWork(sender As System.Object, e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork 

    Dim MyWorkingDirectory = "C:\Windows\System32\" 
    Dim MyFileName As String = "notepad.exe" 
    Dim MyArguments As String = "" 

    Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process() 
    myProcess.StartInfo.WorkingDirectory = MyWorkingDirectory 
    myProcess.StartInfo.FileName = MyFileName 
    myProcess.StartInfo.Arguments = MyArguments 
    myProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden 
    myProcess.Start() 
    ' Wait until it ends. 
    myProcess.WaitForExit() 
    ' Close the process to free resources. 
    myProcess.Close() 

End Sub

我不知道为什么你的代码不能正常工作 - 我想，这是行不通的 - 我想别的建议你：使用一个线程，而不是BackgroundWorker的的。如果你只需要启动应用程序，使用一个简单的线程：

Public Shared Sub ThreadProc() 
    ''Starth the process here! 
End Sub 


Dim t As New Thread(AddressOf ThreadProc) 
t.IsBackground = True 
t.Start() 

而且启动线程打开你需要的进程和主线程继续执行。我希望这是你需要的答案！
