读控制台处理输出

我试图读取一个控制台的过程用下面的代码的全部内容（3秒后）：读控制台处理输出

Dim NewProcess As New System.Diagnostics.Process() 
With NewProcess.StartInfo 
    .FileName = EXE_PATH 
    .RedirectStandardOutput = True 
    .RedirectStandardError = True 
    .RedirectStandardInput = True 
    .UseShellExecute = False 
    .WindowStyle = ProcessWindowStyle.Normal 
    .CreateNoWindow = False 
End With 

NewProcess.Start() 

System.Threading.Thread.Sleep(3000) 

MsgBox(NewProcess.StandardOutput.ReadToEnd)

但是，应用程序似乎试图“ReadToEnd的”时暂停，我想这是因为控制台进程是连续的输出，并且永远不会结束。 'ReadLine'工作正常，但只能获得第一行，但我需要在该阶段的控制台的全部内容。

我该如何解决这个问题？

我会尝试使用Process.OutputDataReceived事件异步读取输出。

请参见：http://msdn.microsoft.com/en-us/library/system.diagnostics.process.outputdatareceived.aspx#Y242

Private Shared processOutput As StringBuilder = Nothing 

Public Shared Sub StartSomeProcess() 
processOutput = new StringBuilder() 
Dim NewProcess As New System.Diagnostics.Process() 
With NewProcess.StartInfo 
    .FileName = EXE_PATH 
    .RedirectStandardOutput = True 
    .RedirectStandardError = True 
    .RedirectStandardInput = True 
    .UseShellExecute = False 
    .WindowStyle = ProcessWindowStyle.Normal 
    .CreateNoWindow = False 
End With 

' Set our event handler to asynchronously read the sort output. 
AddHandler NewProcess.OutputDataReceived, AddressOf OutputHandler 
NewProcess.Start() 
NewProcess.BeginOutputReadLine() 
NewProcess.WaitForExit() 
MsgBox(processOutput.ToString()) 
End Sub 

Private Shared Sub OutputHandler(sendingProcess As Object, outLine As DataReceivedEventArgs)  
     ' Collect the sort command output. 
     If Not String.IsNullOrEmpty(outLine.Data) Then  
      ' Add the text to the collected output. 
      processOutput.AppendLine(outLine.Data) 
     End If 
     End Sub

我将如何实现这到我当前的代码？我已经实施它的方式似乎根本不称之为事件。 – user1293575 2012-04-03 16:15:18

增加了一个示例，没有运行它，所以也许错别字，也做了一些C＃到VB的转换，所以可能不是100％:-) – brendan 2012-04-03 18:26:35

你会如何使用匿名函数？ MSDN似乎暗示它不可能。。。 https://msdn.microsoft.com/en-us/library/system.diagnostics.process.outputdatareceived(v=vs.110).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-2 – 2015-11-24 17:09:39

“对于捕获输出和错误

AddHandler NewProcess.OutputDataReceived, AddressOf OutputHandler 
    AddHandler NewProcess.ErrorDataReceived, AddressOf OutputHandler 

    NewProcess.Start() 
    NewProcess.BeginOutputReadLine() 
    NewProcess.BeginErrorReadLine()
