expression : Expression<Action> -> MethodInfo Similarly to the typeof operator, which provides a refactoring-safe reference to a Type, this method provides a non-string access to an action method:
MethodInfo methodAdd = Reflector.MemberOf(() => default(List<int>).Add(default(int))); // MethodInfo: List<int>.Add() - works without a reference to a ListTo reflect a function method, constructor, property or a field, you can use the MemberOfT(ExpressionFuncT) method.
To reflect methods, you can actually cast the method to a delegate and get its Method property:
MethodInfo methodAdd = ((Action<int>)new List<int>().Add).Method; // MethodInfo: List<int>.Add() - a reference to a List is requiredNote
