Generic retry utility ripped off from SO answer http://stackoverflow.com/a/1563234/34315.

gistfile1.cs

public static class RetryUtility
{
   public static void RetryAction( Action action, int numRetries, int retryTimeout )
   {
       if( action == null )
           throw new ArgumentNullException("action"); // slightly safer...

       do
       {
          try {  action(); return;  }
          catch
          { 
              if( numRetries <= 0 ) throw;  // improved to avoid silent failure
              else Thread.Sleep( retryTimeout );
           }
       } while( numRetries-- > 0 );
   }
}

gistfile2.cs

RetryUtility.RetryAction( () => SomeFunctionThatCanFail(), 3, 1000 );
