Question

I have been trying to get this to work with several tutorials/answers here, but unfortunately have not been able to do so.

I want to do is to execute a process, capture its DefaultOutput and add it to a byte array.
What I got so far is:

private void startProcess(string path, string arguments)
{
    Process p = new Process();
    p.StartInfo.FileName = path;
    p.StartInfo.Arguments = arguments;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.CreateNoWindow = false;
    p.StartInfo.RedirectStandardOutput = true;
    p.StartInfo.RedirectStandardError = true;
    p.OutputDataReceived += p_OutputDataReceived;
    p.EnableRaisingEvents = true;
    p.Start();
    p.BeginErrorReadLine();
    p.BeginOutputReadLine();
    p.WaitForExit();
}

void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
    string str = e.Data;
    // what goes here?!
}

My problem now is: How do I add this data to a (growing) byte array as it comes in or is there another datatype better suited for this purpose?
Also I am not sure where to declare this destination byte array, preferably it would be somewhere in the startProcess Method so I can continue to work with the data after the process Exited, but how could I pass this to p_OutputDataReceived?

Thanks!

You might try a memorystream; it really does what you’re trying to do.
