How to find if a method is implementing specific interface

Question

I have a MehtodBase of a method and I need to know if that method is an implementation of a specific interface. So if I have the following class:

class MyClass : IMyInterface
{
    public void SomeMethod();
}

Implementing the interface:

interface IMyInterface
{
    void SomeMethod();
}

I want to be able to discover at runtime (using reflection) if a certain method implements IMyInterface.

You can use GetInterfaceMap for this.

InterfaceMapping map = typeof(MyClass).GetInterfaceMap(typeof(IMyInterface));

foreach (var method in map.TargetMethods)
{
    Console.WriteLine(method.Name + " implements IMyInterface");
}
