value type inheritance

Question

Hello everyone When dealing with value types I met with two conflicting points 1. We can not inherit one value type from another for example we can not make a struct inherit from another struct; -- I think it means there is no inheritance or derivation for value types. 2. All value types are inherits from ValueType and ValueType is inherits from Object seems value types could have inheritance or derivation? How do you understand the two conflicting points? :-) thanks in advance George

Both are the same struct ( represnting 32 bit Integer ) System.Int32 I think int is a shorthand for writing Int32 which is one of the available integer type. Int16 Int32 Int64

Thanks Alan One further question I think for primitive types there are pairs of relationship example int and Int32 are the same thing only different in names. Is my understanding correct (I can not find answers from any books or search)? regards George

1. No you can't derive from a struct. 2. ValueType from which all structs derive is in fact an abstract class not a struct so there's no inconsistency here.
