Run a method before all methods of a class

Question

Is it possible to do that in C# 3 or 4? Maybe with some reflection?

class Magic
{

    [RunBeforeAll]
    public void BaseMethod()
    {
    }

    //runs Ba

I've recently had cause to do this. I'll spare you the probably boring details of my use-case, except to state that I want the method DoThisFirst to run before the specific method I'm calling. Still learning C# so probably not the best way to do it...

using System;

namespace ConsoleApp1
{
    class Class1
    {
        public enum MethodToCall
        {
            Method2,
            Method3
        }

        public delegate void MyDelegate(int number = 0, bool doThis = false, double longitude = 32.11);

        public static void DoThisFirst(int number, bool doThis, double longitude)
        {
            Console.WriteLine("DoThisFirst has been called.");
        }

        public static void DoSomethingElse(int number, bool doThis, double longitude)
        {
            Console.WriteLine("DoSomethingElse has been called.");
        }

        public static void DoAnotherThing(int number, bool doThis, double longitude)
        {
            Console.WriteLine("DoAnotherThing has been called.");
        }

        public static void Main()
        {
            void Action(MethodToCall methodToCall)
            {
                MyDelegate myDel;

                myDel = new MyDelegate(DoThisFirst);

                switch (methodToCall)
                {
                    case MethodToCall.Method2:
                        myDel += DoSomethingElse;
                        break;
                    case MethodToCall.Method3:
                        myDel += DoAnotherThing;
                        break;
                }

                myDel.Invoke();
            }

            Action(MethodToCall.Method3);

            Console.ReadKey();
        }
    }
}
