Question

I have an Extension Method

public static bool Between<T1, T2>(this T1 Foo, T2 bar) where T1: IComparable
{
     //Body
}

How to restrict my EM so that both T1: IComparable and T2: IConvertible

I tried

T1: IComparable, T2: IConvertible

but gives error. Then how to write?

Answer 1

Try this:

 where T1: IComparable where T2: IConvertible
