I made a program that achieve a knowledge representation, its good but I thing it could be better if I can create and destroy classes on the fly.

If you are talking about dynamic code generation, here is a link:

In C# 3.0 it's possible to create anonymous types, though as STW points out, this is not defined at runtime, but compile time.
var myClass = new { A = 5, Id = "MyClass", num = 0.187f};
Console.WriteLine(myClass.Id);
If you're looking to actually create a new class type on the fly, a round-about way is to generate C# class files, compile them into an assembly, and use Reflection to load the classes.

Anonymous types are neither created, nor "deleted" at runtime. They are standard classes with compiler-generated names and some special permissions/rules--but they are in no way dynamic.

@STW: yes, an important distinction. I had taken the meaning of "dynamic" to mean without explicitly defining a class. However you are quite right.

anonymous types are part of c# 3.0, which is part of .net 3.5 not .net 3.

got an error on this:var myClass = new { int A = 5, string Id = "MyClass", float num = 0.187f}; ...Error 7 An anonymous type cannot have multiple properties with the same name.Framework 3.5

@Ben: C# 3 works perfectly well on .net 2.0 as well.

@erikkallen Technically you are talking about the CLR 2.0 not .net 2.0. Without the assemblies that come with .net 3.5 you cannot use c# 3

@user327104: yeah, sorry, omit the property types.

From your description, it sounds like you don't really want to create C# classes at runtime. What you want is some sort of representation of knowledge.
There is no simple answer to this. This is an area of artificial intelligence research. See http://en.wikipedia.org/wiki/Knowledge_representation_and_reasoning for an introduction.

To me it sounds like you want to learn some AI programming and knowledge representation. However this is far different from creating classes at runtime. Wikipedia gives a rather good introduction into the subject, but no code at all.
