How to wait until my batch file is finished

问题:

I'm doing a program where I need to start cmd and there start up a batch file. The problem is that I'm using MyProcess.WaithForexit(); and I think it does not wait until the batch file processing is finished. It just waits until the cmd is closed. My code so far:

System.Diagnostics.ProcessStartInfo ProcStartInfo =
    new System.Diagnostics.ProcessStartInfo("cmd");
    ProcStartInfo.RedirectStandardOutput = true;
    ProcStartInfo.UseShellExecute = false;
    ProcStartInfo.CreateNoWindow = false;
    ProcStartInfo.RedirectStandardError = true;
    System.Diagnostics.Process MyProcess = new System.Diagnostics.Process();
    ProcStartInfo.Arguments = "/c start batch.bat ";
    MyProcess.StartInfo = ProcStartInfo;
    MyProcess.Start();
    MyProcess.WaitForExit();

I need to wait until the batch file is finished. How do I do that?

回答1:

The start command has arguments that can make it WAIT for the started program to complete. Edit the arguments as show below to pass '/wait':

ProcStartInfo.Arguments = "/c start /wait batch.bat ";

I would also suggest that you want your batch file to exit the cmd envirionment so place an 'exit' at the end of the batch.

@echo off
rem Do processing
exit

This should achieve the desired behavior.

This actually worked just fine for me:

System.Diagnostics.Process.Start("myBatFile.bat").WaitForExit();

As milton said, adding 'exit' at the end of your batch files is most likely a good idea.
