Question

如何使命令行实用程序在 vb.net 的 Async BackgroundWorker 进程中运行？

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

我不确定你的代码为什么不起作用——我想它不起作用——我想给你一些建议：使用线程而不是 BackgroundWorker。如果您只需要启动应用程序，请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()

启动的线程打开您需要的进程，主线程继续执行。我希望这是您需要的答案！
