.NET Forum / .NET Framework / New Users / March 2006Comparer in generics
I developed a comparer class for a base class BEBase public class BEBaseComparer:IComparer<BEBase> ... ... but, i can't use this comparer with a derived class... public class Pippo:BEBase ... I'd like to sort a List<Pippo> using the BEBaseComparer but lista.Sort(bc) where bc is a istance of BEBaseCompare do compiler error!! How can'i do it ?? TIA, Marco Sellani public class BEBaseComparer<T> :IComparer<T> where T:BEBase { public int Compare(T a,T b) { return a.BEBaseProperty ............... } } It is rarely a good idea for a non-generic to inherit from a generic in C#. It is more common in C++ because you can have a base reference the derived class. >I developed a comparer class for a base class BEBase > [quoted text clipped - 15 lines] > > TIA, Marco Sellani Thank you very much.
