public class MyClass : IMyInterface1, IMyInterface2
{
    string IMyInterface1.GetName()

Casting an object to a base type example :

    MyClass obj = new MyClass();

    IMyInterface1 myClass1 = (IMyInterface1)obj;
    IMyInterface2 myClass2 = (IMyInterface2)obj;

    Console.WriteLine("I am : {0}", myClass1.GetName());
    Console.WriteLine("I am : {0}", myClass2.GetName());

    // Outputs :
    // I am : IMyInterface1
    // I am : IMyInterface2
