C# attribute doesnt apply to method

Question

I have the following C# code

 class Program
{
    [My]
    static void Main(string[] args)
    {
        SomeMethod();
    }

    [My]
    static void SomeMethod()
    {
        Console.WriteLine("1111");
    }
}


public class MyAttribute: Attribute
{
    public MyAttribute()
    {
        MessageBox.Show("enter");
    }
    ~MyAttribute()
    {
        MessageBox.Show("leave");
    }

}

Attribute My applies only to method Main (constructor of MyAttribute executes on entering the Main method and destructor executes on leaving them), but not for method SomeMethod.

I need feature like this: execute some portion of code (start and kill the process) in some methods, without modifying them (I think, that the attributes may be the best decision).

Please, help

What you want to do isn't what attributes can do (at least not by itself). An attribute is just a tag to mark a method/class/property. What you do with it after that is up to you but it generally involves using reflection or 3rd party libarary to do the heavy lifting. — Dirk, Aug 20 '14 at 13:02

You are not using the attributes in the correct way:

Attributes should indicate a property of a class or a class member and in most of the cases are used by the consumer of the object.

Very often attributes are used with reflection to get information:

System.Attribute[] attrs = System.Attribute.GetCustomAttributes(t);
