 Q:

Generic type checking

Is there a way to enforce/limit the types that are passed to primitives? (bool, int, string, etc.)
Now, I know you can limit the generic type parameter to a type or interface implementation via the where clause. However, this doesn't fit the bill for primitives (AFAIK) because they do not all have a common ground (apart from object before someone says! :P).
So, my current thoughts are to just grit my teeth and do a big switch statement and throw an ArgumentException on failure..

EDIT 1:
Just to clarify:
The code definition should be like:
public class MyClass<GenericType>....

And instantiation:
MyClass<bool> = new MyClass<bool>(); // Legal
MyClass<string> = new MyClass<string>(); // Legal
MyClass<DataSet> = new MyClass<DataSet>(); // Illegal
MyClass<RobsFunkyHat> = new MyClass<RobsFunkyHat>(); // Illegal (but looks awesome!)

@Jon Limjap - Good point, and something I was already considering.. I'm sure there is a generic method that can be used to determine if the type is of a value or reference type..
This could be useful in instantly removing a lot of the objects I dont want to deal with (but then you need to worry about the structs that are used such as Size ).. Interesting problem no?

 Generic type checking 

 Is there a room to enforce / limit the types that are fall to primitives? (bool, int, string, etc .) 
 nowadays, I know you can limit the generic character parameter to a type or interface implementation via the where clause. However, this doesn't equip the bill for primitive (AFAIK) because they do not all have a common land (apart from object before someone says! :P). 
 indeed, my current thoughts are to just grit my teeth and do a large switch statement and throw an ArgumentException on failure.. 

 EDIT 1: 
 Just to clarify: 
 The code definition should be like: 
 public course MyClass < GenericType >.... 

 And instantiation:
