C# supports value types and reference types, but are they all objects?

Question

I know C# has both value and reference types, but how can you do a this: ``` int age = 100; string blah = age.ToString(); ``` If age is a value type, how does it have a ToString method on it? Does it get converted to an object ONLY when required internally then?

Accepted Answer

You want to look up boxing/unboxing.
