A quick and simple timer class to wrap

timeit.cs

using (new TimeIt()) { command.Execute(); }    

    public class TimeIt : IDisposable
    {
        private readonly TextWriter output;
        private readonly Stopwatch watch;

        public TimeIt() : this(Console.Out) {}

        public TimeIt(TextWriter output)
        {
            this.output = output;
            watch = Stopwatch.StartNew();
        }

        public void Dispose()
        {
            output.WriteLine("Execution took : " + watch.Elapsed);
        }
    }
