Why don't you look up Process class in MSDN (after all, you ARE using it)? If you had done that, you would have found the WaitForExit method.

foreach (var filename in files)
{
    Process.Start("c:\\Telock\\Telock.exe", " -S" + filename.ToString()).WaitForExit();
}

Take for habit to use more descriptive variable names (i doesn't really say anything, especially not for a filename).
