Question

我知道如何通过startinfo.arguments将参数发送到子程序。我想我甚至知道如何“倾听”孩子可能通过standardoutput.readline“说”的任何事情。我不知道的是用什么方法让孩子“说话”回父母。这是我到目前为止的代码（在父方面）：

Dim proc As Process
Dim bRunProgramWorked As Boolean = True
Try
    proc = New Process
    Dim procInfo As New ProcessStartInfo
    proc.StartInfo.FileName = strPathUpgradeEXE
    proc.StartInfo.Arguments = param1 & " " & param2 & " " & param3
    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
    'proc.StartInfo.WindowStyle = ProcessWindowStyle.Maximized
    proc.StartInfo.UseShellExecute = False
    proc.StartInfo.CreateNoWindow = True
    proc.StartInfo.RedirectStandardOutput = True
    'proc.StartInfo.RedirectStandardError = True
    proc.Start()
    Dim output1 As String = proc.StandardOutput.ReadLine
    Dim output2 As String = proc.StandardOutput.ReadLine
    proc.WaitForExit()
    proc.Close()
    proc.Dispose()
Catch ex As Exception
    LogIt(strMyBaseID, "Error at trying to run PVT-Export. " & ex.ToString)
    bRunProgramWorked = False
End Try

Answer 1

子进程需要写入Console.Out。

使用“进程”调用另一个程序。想要将信息传递回父程序
