How to catch output of shell program or any other process

Example from my blog. Shows how to catch output of any process. I tested this code using netstat.exe as process to run.

<%@ Import Namespace="System.Diagnostics" %>
<script runat="server" language="C#">
private void Page_Load()
{
    string sPath = "path to my program";
 
    ProcessStartInfo proc = new ProcessStartInfo(sPath, "");
    proc.RedirectStandardOutput = true;
    proc.UseShellExecute = false;
 
    Process p = Process.Start(proc); 
    p.Start();
    this.lblOut.Text = p.StandardOutput.ReadToEnd();
    p.Dispose();
}
</script>

<head>
    <title>Shell program output</title>

<body>
    <form runat="server">
    <pre><asp:Label runat="server" id="lblOut"></asp:Label></pre>
    </form>
