Redirect standart stream (Process.Start)

I have the following code:

 private void button1_Click(object sender, EventArgs e)
    {
        Process process = new Process();
        ProcessStartInfo processStartInfo = new ProcessStartInfo();

        processStartInfo.Arguments = "-i 1 -x";
        processStartInfo.CreateNoWindow = false;
        processStartInfo.FileName = @"F:\NET\WiresharkPortable\App\Wireshark\tshark.exe";
        processStartInfo.RedirectStandardOutput = true;
        processStartInfo.UseShellExecute = false;
        process.StartInfo = processStar开发者_JAVA百科tInfo;
        process.Start();

        StreamReader streamReader = process.StandardOutput;
        textBox1.AppendText(streamReader.ReadToEnd() + "\r\n");
    }

I'm trying to redirect the output to my program. tshark is sniffer, so it works until was suspended. How to redirect data in real time? Thanks.


You're currently calling ReadToEnd, which will block to the end of the stream.

You could either repeatedly call Read from a separate thread, or you could use the newer eventing approach, handling Process.OutputDataReceived for each line after calling BeginOutputReadLine. Don't forget to marshal back to the UI thread before changing the textbox.
