Answer 1

First, you would call typeof(MyClass).GetMethods() to get an array of all the methods defined on that type, then you loop through each of the methods it returns and call methodInfo.GetCustomAttributes(typeof(MyCustomAttribute), true) to get an array of custom attributes of the specified type. If the array is zero-length then your attribute is not on the method. If it's non-zero, then your attribute is on that method and you can use MethodInfo.Invoke() to call it.
