Performance Timer Logging

[Costas]

var timer = Stopwatch.StartNew();
var ms = timer.ElapsedMilliseconds;

Just 2 Lines and no ugly indenting of my code. There is really no need to stop the Stopwatch. No resources will be freed if you do, it just stops counting.

using System.Diagnostics;
 
var timer = new Stopwatch();
timer.Start();
 
// do something you want to profile
 
timer.Stop();
var ms = timer.ElapsedMilliseconds;
 
// write timing to logs

First, here's the usage example of the performance timing logging class that will be listed below:

using (new PerfTimerLogger("name of code being profiled"))
{
    // do something you want to profile
}

Now, as you can see the above code is MUCH simpler to implement within your code and not very intrusive. Basically, 2 lines of code, instead of 4; and not extra variables to keep track of.

Here's an implementation of the PerfTimerLogger class that allows it to be used as the above example demonstrates:

using System.Diagnostics;
 
public class PerfTimerLogger : IDisposable
{
    public PerfTimerLogger(string message)
    {
        this._message = message;
        this._timer = new Stopwatch();
        this._timer.Start();
    }
 
    string _message;
    Stopwatch _timer;
 
    public void Dispose()
    {
        this._timer.Stop();
        var ms = this._timer.ElapsedMilliseconds;
 
        // log the performance timing with the Logging library of your choice
        // Example:
        // Logger.Write(
        //     string.Format("{0} - Elapsed Milliseconds: {1}", this._message, ms)
        // );
    }
}
