copied!<p>Your question is a little confusing but I think i see your problem. First you should check out this blog post to see <a href="http://csharptest.net/?p=321" rel="noreferrer">common issues with System.Diagnostics.Process</a>. Your code happens to violate one that isn't listed there. The reuse of the Process object itself.</p> <p>You need to refactor the code like:</p> <pre><code> class MyProcessStarter { private ProcessStartInfo _startInfo = new ProcessStartInfo(); public MyProcessStarter(string exe, string workingDir) { _startInfo.WorkingDirectory = workingDir; _startInfo.FileName = exe; _startInfo.UseShellExecute = false; _startInfo.RedirectStandardOutput = true; } public string Run(string arguments) { _startInfo.Arguments = arguments; Process p = Process.Start(_startInfo); p.Start(); string strOutput = p.StandardOutput.ReadToEnd(); p.WaitForExit(); return strOutput; } } </code></pre> <p>I've written a more complete and accurate implementation called <a href="http://code.google.com/p/csharptest-net/source/browse/#svn/trunk/src/Library/Processes" rel="noreferrer">ProcessRunner</a>. The following demonstrates it's usage to perform the same operation:</p> <pre><code>using CSharpTest.Net.Processes; partial class Program { static int Main(string[] args) { ProcessRunner run = new ProcessRunner("svn.exe"); run.OutputReceived += new ProcessOutputEventHandler(run_OutputReceived); return run.Run("update", "C:\\MyProject"); } static void run_OutputReceived(object sender, ProcessOutputEventArgs args) { Console.WriteLine("{0}: {1}", args.Error ? "Error" : "Output", args.Data); } } </code></pre>
