How to Detect Process Exit

Sometimes it is a common task in .NET applications to start some command-line process using System.Diagnostics.Process. Like so:

Process proc = new Process();
proc.StartInfo.FileName = "mycommand.cmd";
proc.Start();

However it is a bit more complicated task to determine when the Process exited or the command finished its work. 2 handy properties of Process would help: HasExited and WaitForExit:

do 
{              
    if (!proc.HasExited)
    {
        proc.Refresh();
    }
}
while (!proc.WaitForExit(1000));

// exited here - do work

Enjoy :)
