System.Diagnostic.Process

[Guest]

Does anyone know the best way to interact with a command application using
System.Diagnostic.Process if the command application never exits?

In other words, The OnOutputRecieved event doesn't fire until the app
exists, which is not too helpful because I want to interact with the app
while it's running.

Here's my code:

// Set UseShellExecute to false for redirection
_proc.StartInfo.UseShellExecute = false;
_proc.EnableRaisingEvents = true;

// Redirect the standard output of the command.
// This stream is read asynchronously using an event handler.
_proc.StartInfo.RedirectStandardOutput = true;

_proc.StartInfo.RedirectStandardError = redirectStandardError;

// Redirect standard input as well. This stream
// is used synchronously.
_proc.StartInfo.RedirectStandardInput = true;

_proc.StartInfo.CreateNoWindow = true;
_proc.StartInfo.WorkingDirectory = somePathISpecified;
_proc.StartInfo.FileName = commandPath;
_proc.StartInfo.Arguments = arguments;
_proc.Start();

// Start the asynchronous read of the output stream.
_proc.BeginOutputReadLine();

Now, this works fine if it's not a blocking process, but reading output, and
passing input doesn't seem to work if the process doesn't exit.

Thanks for any help

I found this article that looks like it'll be a big help if anyone else runs
