异步重定向StandardOutput和StandardError

我试图重定向一个长过程的标准输出和标准错误。这是一个可能需要40分钟才能完成处理的Exe文件。

问题是，如果我从命令行(cmd)运行EXE, stdout和stderr以某种顺序显示在控制台上，这是我希望它从我的应用程序重定向的顺序，但它不起作用。我在使用以下函数的时候改变了顺序，找不到原因是什么。我希望你能给我一些建议。

这是我使用的代码:

Public numOutputLines As Integer = 0
Public sortOutput As StringBuilder = Nothing

Public Function ProcessTask3New(ByVal ExeName As String, ByVal arguments As String, ByRef stdout As String, ByRef stderr As String, ByRef ExitCode As Integer, _
                                  Optional ByVal Filename As String = "", Optional ByVal IsDeleteTempLogFiles As Boolean = False) As Boolean
        ' This fucntion executes cmd commands and arguments,
        ' Function returns standard output and startdard error. stderr contains data if error was generated 

        Try
            ProcessTask3New = True
            Dim p As Process
            Dim psi As ProcessStartInfo

            Dim currentTime As System.DateTime
            currentTime = System.DateTime.Now
            If Filename <> "" Then Filename = Replace(Filename & ".", "'", "")
            Dim tmpStdoutFilename As String = System.IO.Path.GetTempPath & "stdout." & Filename & currentTime.Ticks.ToString()
            Dim tmpStderrFilename As String = System.IO.Path.GetTempPath & "stderr." & Filename & currentTime.Ticks.ToString()

            netOutput = New StringBuilder
            p = New Process
            psi = p.StartInfo
            psi.Arguments = psi.Arguments.Replace("/C " & Chr(34), "/C " & Chr(34) & Chr(34))
            psi.FileName = ExeName
            psi.UseShellExecute = False
            psi.WindowStyle = ProcessWindowStyle.Minimized
            ' Redirect the standard output of the sort command.   
            ' Read the stream asynchronously using an event handler.
            psi.RedirectStandardOutput = True
            psi.RedirectStandardError = True
            psi.CreateNoWindow = True
            sortOutput = New StringBuilder()
            ' Set our event handler to asynchronously read the sort output. 
            AddHandler p.OutputDataReceived, _
                       AddressOf SortOutputHandler

            AddHandler p.ErrorDataReceived, AddressOf SortOutputHandler


            If IsDebug Then Write2Log("ProcessTask3New: " + psi.FileName.ToString + " " + psi.Arguments.ToString)
            Try
                Write2Log(My.Computer.FileSystem.CurrentDirectory)
                p.Start()
            Catch w As System.ComponentModel.Win32Exception
                Write2Log("ProcessTask3New: " & w.Message)
                Write2Log("ProcessTask3New: " & w.ErrorCode.ToString())
                Write2Log("ProcessTask3New: " & w.NativeErrorCode.ToString())
                Write2Log("ProcessTask3New: " & w.StackTrace)
                Write2Log("ProcessTask3New: " & w.Source)
                Dim e As New Exception()
                e = w.GetBaseException()
                Write2Log("ProcessTask3New: " & e.Message)
            End Try


            ' Start the asynchronous read of the sort output stream.
            p.BeginOutputReadLine()
            p.BeginErrorReadLine()
            p.WaitForExit()
            ExitCode = p.ExitCode
            p.Close()

            netOutput = Nothing
        Catch ex As Exception
            Write2Log("error at ProcessTask3New function: " & ex.ToString & " : " + ex.StackTrace)
        End Try
    End Function
    Private Sub SortOutputHandler(ByVal sendingProcess As Object, _
       ByVal outLine As DataReceivedEventArgs)
        ' Collect the sort command output. 
        If Not String.IsNullOrEmpty(outLine.Data) Then
            numOutputLines += 1
             Add the text to the collected output.
            sortOutput.Append(Environment.NewLine + "[" _
                         + numOutputLines.ToString() + "] - " _
                         + outLine.Data)
        End If
    End Sub

现在输出这是我从cmd窗口运行它时的样子(这很好):
