Logging Aspect Interceptor

gistfile1.cs

public class LoggingAspect : IInterceptor
	{
		private readonly ILogger logger;
		private readonly Stopwatch stopwatch;

		public LoggingAspect(ILogger logger)
		{
			this.logger = logger;
			this.stopwatch = new Stopwatch();
		}

		public void Intercept(IInvocation invocation)
		{
			var parameterNames = invocation.Request.Method.GetParameters().Select(p => p.Name).ToList();
			var parameterValues = invocation.Request.Arguments;
			var message = new StringBuilder();
			message.Append(string.Format("~Method '{0}.{1}'~Parameters ",invocation.Request.Target.GetType().Name, invocation.Request.Method.Name));

			GetParameterInformation(parameterNames, parameterValues, message);

			message.Append("~");
			this.stopwatch.Start();
			invocation.Proceed();
			this.stopwatch.Stop();

			message.Append(string.Format("~ {0}", this.stopwatch.ElapsedMilliseconds));
			this.logger.LogInfo(message.ToString());
			this.stopwatch.Reset();
		}

		private static void GetParameterInformation(IList<string> parameterNames, IList<object> parameterValues, StringBuilder message)
		{
			for (var index = 0; index < parameterNames.Count; index++)
			{
				var name = parameterNames[index];
				var value = parameterValues[index];
				message.Append(string.Format("<{0}>:<{1}>,", name, value));
			}
		}
	}

The following using statements are required:
using Ninject.Extensions.Interception.Infrastructure.Language;
using Ninject.Modules;

This is also required Ninject.Extensions.Interception.DynamicProxy

You can then apply interceptor for a service using .Intercept().With();
