Using Attributes to Call Methods

Question

I have various individual methods which all need to perform the same functions before continuing on with their own implementation. Now I could implement these functions in each

Answer 1

You can use PostSharp, it is aspect-oriented framework for .NET, it seems quite easy to use:

static void Main(string[] args)
{
    Foo();
}

[IgnoreMethod(IsIgnored=true)]
public static void Foo()
{
    Console.WriteLine("Executing Foo()...");
}

[Serializable]
public class IgnoreMethodAttribute : PostSharp.Aspects.MethodInterceptionAspect
{
    public bool IsIgnored { get; set; }

    public override void OnInvoke(PostSharp.Aspects.MethodInterceptionArgs args)
    {
        if (IsIgnored)
        {
            return;
        }

        base.OnInvoke(args);
    }
}

Run-Time Performance:

Because PostSharp is a compiler technology, most of the expensive work is done at build time, so that applications start quickly and execute fast. When generating code, PostSharp takes the assumption that calling a virtual method or getting a static field is an expensive operation. Contrary to rumor, PostSharp does not use System.Reflection at run time. http://www.sharpcrafters.com/postsharp/performance
