麻烦在C＃中处理批处理文件

Question

my code is :

Process myProcess = new Process();
myProcess.StartInfo.FileName = @"batchfile.bat";
myProcess.StartInfo.Arguments = "some argument";
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.CreateNoWindow = true;
myProcess.StartInfo.RedirectStandardInput = true;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.Start();
StreamReader sr = myProcess.StandardOutput;
textBox1.Text = sr.ReadToEnd();

myProcess.WaitForExit();

it works but i want to get asynchronous output.

thanks for any help.

Answer 1

Basically, you need to enable asynchronous read operations on StandardOutput .

To start asynchronous read operations, you must redirect the StandardOutput stream of your batch, add an event handler to the OutputDataReceived event, and call BeginOutputReadLine . Thereafter, the OutputDataReceived event signals each time the batchwrites a line to the redirected StandardOutput stream.

You will finc a complete example on MSDN .

Process class also exposes a StandardInput property that allows you to send a command to the standard input of the process.
