Here is some as-is code for helping with System.Diagnostics.Process

[hellosticky]

Thought I would throw this out there so that it could be Google'd.
Deals with a common use of Process which is to encapsulate another
process and grab its standard out and standard error, and so it uses
the asynchronous operations that the Process class provides. Sorry for
lack of commenting. This code is provided As Is, with no warranty
implied, and can be used for any purpose, royalty free.

// Common usage:
ProcessHelper realProcess = new ProcessHelper();
realProcess.FileName = @"c:\program
files\subversion\bin\svn.exe";
realProcess.SetArguments("info");
realProcess.Start(true);

public class ProcessHelper

private Process m_process = new Process();
private TextWriter m_error = Console.Error;
private TextWriter m_out = Console.Out;

public ProcessHelper()
{
m_process.ErrorDataReceived += new
DataReceivedEventHandler(process_ErrorDataReceived);
m_process.OutputDataReceived += new
DataReceivedEventHandler(process_OutputDataReceived);

Updated version of SetArguments method:

public void SetArguments(params string[] args)
{
StringBuilder sb = new StringBuilder();
int c = 0;
bool containsSpace;
foreach (string val in args)
{
if (c > 0)
{
sb.Append(' ');
}
containsSpace = (val.IndexOf(' ') != -1);
if (containsSpace)
{
sb.Append('\"');
}
sb.Append(val);
if (containsSpace)
{
sb.Append('\"');
}
c++;
}
Arguments = sb.ToString();
}
