Look into reflection.

Answer 2

[MyAttribute("Hello World")]
public int MyMethod()
{
var myAttribute = GetType().GetMethod("MyMethod").GetCustomAttributes(true).OfType<MyAttribute>().FirstOrDefault();
}

Answer 3

You need to call the GetCustomAttributes function on a MethodBase object.
The simplest way to get the MethodBase object is to call MethodBase.GetCurrentMethod. (Note that you should add [MethodImpl(MethodImplOptions.NoInlining)])

For example:

MethodBase method = MethodBase.GetCurrentMethod();
MyAttribute attr = (MyAttribute)method.GetCustomAttributes(typeof(MyAttribute), true)[0] ;
string value = attr.Value;    //Assumes that MyAttribute has a property called Value

You can also get the MethodBase manually, like this: (This will be faster)

MethodBase method = typeof(MyClass).GetMethod("MyMethod");
