Excluding Types in the Generic Constraints (Possible?)

Question

Is possible to exclude specific types from the set of possible types, that can be used in a generic parameter? If so how.

For example

Foo()         


        

Answer 1

Nope, you can't make one-off exclusions like that using type constraints. You can do it at runtime though:

public void Foo<T>()
{
     if (typeof(T) == typeof(bool))
     {
         //throw exception or handle appropriately.
     }
}
