Use typeof in generic class

Question

I Create Generic class like this:

public class Sample<T> where T : class
{
    public DoSomething();
}

then I create new class :

public class Sample2
{
    Sample<Sample2> obj=new Sample<Sample2>();
}

why can't i use the below code to create an instance of Sample class in Sample2 class?

        Sample<typeof<this>> obj=new Sample<typeof<this>>();

Answer is simple Generics need to be Compile time but what you're doing is obviously not known during Compile time
