C#/.NET Little Wonders: The Predicate, Comparison, and Converter Gener(blackrabbitcoder.net)

submitted by BlackRabbitCoder(661) 6 months, 1 day ago

In the last three weeks, we examined the Action family of delegates (and delegates in general), the Func family of delegates, and the EventHandler family of delegates and how they can be used to support generic, reusable algorithms and classes. This week I will be completing my series on the generic delegates in the .NET Framework with a discussion of three more, somewhat less used, generic delegates: Predicate<T>, Comparison<T>, and Converter<TInput, TOutput>. These are older generic delegates that were introduced in .NET 2.0, mostly for use in the Array and List<T> classes. Though older, it’s good to have an understanding of them and their intended purpose. In addition, you can feel free to use them yourself, though obviously you can also use the equivalents from the Func family of delegates instead.
