Base clase

[delhiris]

Which is base class in .NEt (maybe ASP.Net) ?
I have this question on interview?

Following functionality encapsulated by the base class library.
Simple types, IO, Text, Threading, Remoting, Reflection, Debug & Diagnostics, Net, Configuration, and Globalization etc.

I'm sure this is not what he is asking but you could be a smartie and answer with 'object' :P

Object Class
Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework; it is the root of the type hierarchy.
