Constraints on Type parameters [duplicate]

generics

Is there a way to constraint a generic type to only integral type?

In example, if I have a method

T[] sort<T>(T[] data) where : T ... {}

what would I put as constraint if I wanted to ensure the parameter will be some sort of integral type?

I have tryed looking at MSDN however it does not seem to mention anything about constraining and primitive types.

Thank you for your help.

Nope. I asked this question before with VB.Net.

Generic Classes (T) - Specifying from a Range of Types VB.Net

As quoted from the page above:
Also, you mentioned constraining to numerics, but I don't think you can constrain to just that. You can however constrain to just primitive types (on the stack) and not allow objects (on the heap) by doing this: Public Structure Statistic(Of t As {Structure, IComparable}).
