Is there an existing delegate in the .NET Framework for comparison?

Question

The .NET framework provides a few handy general-use delegates for common tasks, such as Predicate<T> and EventHandler<T>.

Is there a built-in delegate for the equivalent of CompareTo()?

The signature might be something like this:

delegate int Comparison<T>(T x, T y);

This is to implement sorting in such a way that I can provide a lambda expression for the actual sort routine (ListView.ListViewItemSorter, specifically), so any other approaches welcome.

Answer 1

Look for: System.Collections.Generic.Comparer<T>

Answer 2

You even got the names right :)

See System.Comparison<T>

Answer 3

Why not just use Func?

void Example<T>(Func<T,T,int> comparereDel) {
  ...
}
