From where can i get CTS hierarchy ? where does interface type fits in the CTS hierarchy

Question

It says there are basically two types 1) Value type and reference type. all value types are dereived from system.valuetype

1) Is there any thing like system.referencetype , because every CTS hierarchy i have seen shows two types below system.objects , a Valuetype and a Referencetype

My understanding is all types that are derieved from system.objects except system.valuetype are reference .Is this correct ?

2) And where does interface type fits in the hierarchy . Some diagrams it is show independently but in some it comes under the reference type .

3) From where can I get the actual CTS hierachy diagram ?

Answer 1

Both reference and value types are derived from the ultimate base class Object. Interfaces are reference types. this one is goor reference to CTS http://msdn.microsoft.com/en-us/library/ms173104.aspx
