C#功能请求:在匿名类型上实现接口

public interface IMyInterface
{
    void MyMethod();
}

public class MyClass
{
    public void MyMethod()
    {
        Console.WriteLine("MyMethod called");
    }
}

public static void Main(string[] args)
{
    IMyInterface myInterface = new MyClass();
    myInterface.MyMethod();
}

public interface IMyInterface
{
    void MyMethod();
}

public static void Main(string[] args)
{
    dynamic myInterface = new ExpandoObject();
    myInterface.MyMethod = new Action(() =>
    {
        Console.WriteLine("MyMethod called");
    });

    myInterface.MyMethod();
}
