在单独的程序中将控制台输出重定向到文本框

这对我有用:

void RunWithRedirect(string cmdPath)
{
    var proc = new Process();
    proc.StartInfo.FileName = cmdPath;

    // set up output redirection
    proc.StartInfo.RedirectStandardOutput = true;
    proc.StartInfo.RedirectStandardError = true;    
    proc.EnableRaisingEvents = true;
    proc.StartInfo.CreateNoWindow = true;
    // see below for output handler
    proc.ErrorDataReceived += proc_DataReceived;
    proc.OutputDataReceived += proc_DataReceived;

    proc.Start();

    proc.BeginErrorReadLine();
    proc.BeginOutputReadLine();

    proc.WaitForExit();
}

void proc_DataReceived(object sender, DataReceivedEventArgs e)
{
    // output will be in string e.Data
}
