Anonymous IComparer implementation

Question

Is it possible to define an anonymous implementation of IComparer?

I believe Java allows anonymous classes to be defined inline - does C#?

Looking at this code I

Answer 1

As indicated in one of the comments below, .Net 4.5 allows this via a static method on the Comparer<> class, e.g. comparing two objects based on the value of a property in the class:

var comparer = Comparer<KilowattSnapshot>.Create( 
        (k1, k2) => k1.Kilowatt.CompareTo(k2.Kilowatt) );

Obviously this can be used inline rather than assigned to a variable.

Answer 2

The .NET framework version 4.5 provides the method Comparer.Create(Comparison) to create comparers based on a specified comparison delegate (which can be a lambda function). However people who are working with earlier versions of .NET will probably need to implement something similar themselves.
