MethodBoundaryAspect.Fody

NuGet package https://www.nuget.org/packages/MethodBoundaryAspect.Fody/

Introduction

Allows decorated method to access some runtime properties before and after method execution.

 public class MethodExecutionArgs
  {
    public object Instance { get; set; }
    public MethodBase Method { get; set; }
    public object[] Arguments { get; set; }
    public object ReturnValue { get; set; }
    public Exception Exception { get; set; }
    public object MethodExecutionTag { get; set; }
  }

Your Code

	public sealed class TransactionScopeAttribute : OnMethodBoundaryAspect
    {
        public int TimeoutInSeconds { get; set; }

        public override void OnEntry(MethodExecutionArgs args)
        {
            var transactionScopeProvider = GlobalServiceLocator.ServiceLocator.GetInstance<ITransactionScopeProvider>();

            if (TimeoutInSeconds != 0)
                transactionScopeProvider.Timeout = TimeSpan.FromSeconds(TimeoutInSeconds);

            var transactionScope = transactionScopeProvider.Create();
            args.MethodExecutionTag = transactionScope;
        }

        public override void OnException(MethodExecutionArgs args)
        {
            FinishTransaction(args);
        }

        public override void OnExit(MethodExecutionArgs args)
        {
            FinishTransaction(args);
        }

        private static void FinishTransaction(MethodExecutionArgs args)
        {
            var transactionScope = (ITransactionScope)args.MethodExecutionTag;

            try
            {
                if (args.Exception == null)
                    transactionScope.Complete();
            }
            finally
            {
                if (transactionScope != null)
                    transactionScope.Dispose();
            }
        }
    }

	public class Sample
	{
		[TransactionScope]
		public void Method()
		{
		    Debug.WriteLine("Do some database stuff isolated in surrounding transaction");
		}
	}
