How can I implement performance logging in C#?

You can use libraries like NLog or log4net for performance logging in C#. Would you like a code example?

Yes, please provide a code example using NLog.

Here's a simple example:

using NLog;

class Program
{
    private static readonly Logger Logger = LogManager.GetCurrentClassLogger();

    static void Main(string[] args)
    {
        Logger.Info("Application started.");
        // Your code here
        Logger.Info("Application finished.");
    }
}

This logs messages when the application starts and finishes.

How can I log the execution time of a method?

You can use a stopwatch to measure execution time. Here's an example:

using System.Diagnostics;

public void MyMethod()
{
    Stopwatch stopwatch = Stopwatch.StartNew();
    // Your method logic here
    stopwatch.Stop();
    Logger.Info($"Execution time: {stopwatch.ElapsedMilliseconds} ms");
}
