How do ValueTypes derive from Object (ReferenceType) and still be ValueTypes?

I am able to write the code like this,

String s = 10.ToString();

ToString() will only come when that particular object is inheriting class ‘Object'(ofcourse all the classes inherits Object in c#). Is it number 10 also inheriting the class ‘object’. If so how?

Answer 1

Is it number 10 also inheriting the class ‘object’. If so how?

The literal 10 is, per the specification, interpreted by the compiler as an instance of Int32. Int32 inherits from object. Thus, 10 is an instance of a type that inherits from object. As such, it has an instance method named ToString.
