如何从Visual C＃.NET代码运行批处理文件并检索结果？

Question

I have created a getSvnUrl.bat

containing the following code

@ECHO OFF
for /f "tokens=1-2" %%i in ('"%VISUALSVN_SERVER%\bin\svn.exe" info     C:\\Code\\ServiceRouter153\\SCM\\Configs\\ServiceRouter_MIGRATION.xml') do (
    if "%%i"=="URL:" (
    set URL=%%j
    )
)
echo The result is.. %URL% 

I would like to run this .bat from C# .NET code and be able to collect the SVN url contained the URL variable in a String variable in C#.

I tried this C# code from an 11 year old MSN blog http://blogs.msdn.com/b/csharpfaq/archive/2004/06/01/146375.aspx

It is not working. Is there a new way to do this?

    private void runSyncAndGetResults_Click(object sender, System.EventArgs e)
    {
        System.Diagnostics.ProcessStartInfo psi =
          new System.Diagnostics.ProcessStartInfo(@"C:\getSvnUrl.bat");
        psi.RedirectStandardOutput = true;
        psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        psi.UseShellExecute = false;
        System.Diagnostics.Process listFiles;
        listFiles = System.Diagnostics.Process.Start(psi);
        System.IO.StreamReader myOutput = listFiles.StandardOutput;
        listFiles.WaitForExit(2000);
        if (listFiles.HasExited)
        {
            string output = myOutput.ReadToEnd();
            this.processResults.Text = output;
        }
    }

Here is the method I ended up using in case it ever helps someone else.

    private string runBatchGetSvnUrl()
    {
        System.Diagnostics.ProcessStartInfo psi =
          new System.Diagnostics.ProcessStartInfo(@"C:\getSvnUrl.bat");
        psi.RedirectStandardOutput = true;
        psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        psi.UseShellExecute = false;
        System.Diagnostics.Process listFiles;
        listFiles = System.Diagnostics.Process.Start(psi);
        System.IO.StreamReader myOutput = listFiles.StandardOutput;
        listFiles.WaitForExit(2000);
        if (listFiles.HasExited)
        {
            string output = myOutput.ReadToEnd();
            return output;
        }
        else
        {
            return "It didn't work.";
            //change this to throw an excetion later


        }

    }
