As per the above link….. “Structs, however, inherit from the base class Object……”

As per the below link
http://msdn.microsoft.com/en-us/library/system.valuetype.aspx
Struct is implemented after ValueType in the hierarchy.

“struct” is derived from which class? Or compiler treats “struct” reserve word to make any declaration using “struct” as value type?
Missing the small thread in overall understanding.
Thank you for your help.

Answer 1

The hierarchies (skipping any class subtypes) are:

1. struct .. -> ValueType -> Object

2. class .. -> Object

Demo:

struct S {}
class C {}

// or see `is` as per Jeff Mercado's comment
typeof(ValueType).IsAssignableFrom(typeof(S)); // True
typeof(object).IsAssignableFrom(typeof(S));    // True

typeof(ValueType).IsAssignableFrom(typeof(C)); // False
typeof(object).IsAssignableFrom(typeof(C));    // True
