Cast MyClass<T> to MyClass<dynamic>

The follow code does not compile:

public class Test
{
    public void Run()
    {
        List<MyClass<dynamic>> listOfMyClasses = new List<MyClass<dynamic>>();

        MyClass<dynamic> myClass = new MyClass<int>(); // Error here

        listOfMyClasses.Add(myClass);
    }

    public class MyClass<T>
    {
        public void DoSomething() { }
        public void DoSomethingSpecial<T>(T t) { }
    }
}

However, I believe it makes sense logically (please let me know if I'm mistaken). Presumably it is useful, for I can call DoSomething without knowing the type parameter. How can I accomplish the addition of myClass to the list?

Instead of using a list of MyClass<dynamic> just use a List of dynamic :

    public void Run()
    {
        List<dynamic> listOfMyClasses = new List<dynamic>();

        dynamic myClass = new MyClass<int>();

        listOfMyClasses.Add(myClass);
    }

    public class MyClass<T>
    {
        public void DoSomething() { }
    }
