c# - How to redirect process output to System.String

Question

I am calling Java process from .NET application and I need to redirect console output to System.String to do some later parsing. Please advice. I would appreciate short code example.

public bool RunJava(string fileName)
{
    try
    {
        ProcessStartInfo psi = new ProcessStartInfo();
        psi.CreateNoWindow = true;
        psi.UseShellExecute = false;
        psi.EnvironmentVariables.Add("VARIABLE1", "1");
        psi.FileName = "JAVA.exe";
        psi.Arguments = "-Xmx256m jar.name";

        Process.Start(psi);
        return true;
    }
    catch (Exception ex)
    {
        return false;
    }
}

A better way will be to create a Process instance and capture the output using a stream like this:

Process cmd = new Process();
cmd.StartInfo.FileName = "JAVA.exe";
cmd.StartInfo.Arguments = "-Xmx256m jar.name";
cmd.StartInfo.UseShellExecute = false;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.EnvironmentVariables.Add("VARIABLE1", "1");
cmd.Start();

StreamReader sr = cmd.StandardOutput;
string output = sr.ReadToEnd();
cmd.WaitForExit();
