C# - How do I GetType of 'class with generic parameter' in run-time?

I have a generic class as shown below:

using System.Collections.Generic;

namespace MyNameSpace
{
    public class MyClass<T> : MyAnotherClass
    {
        public MyClass();
        public MyClass(T obj);
        public T Object { get; set; }
    }
}

I don't understand why following line of code return null (throwing exception with message : "Could not load type 'MyClass' from assembly '//assembly details//' ")

Type MyClassType = AssemblyContaingMyClass.GetType("MyNameSpace.MyClass");

Is it illegal to use Assembly.GetType(className) with generic class?

Can you suggest any alternate method to get type of generic class in run-time?

Thanks in advance and Apology if this question is too basic. I am new to c#.

EDIT :

Forgot to mention. the assembly containing MyClass will be loaded run-time.
