Predicate delegate in C#

Hello Everyone, In the article we will talk about Predicate delegate.

Predicate is also a delegate which encapsulate a method that takes  only one parameter and returns a bool value - true or false.

So in general Predicate is -

1. Which is contra variant

2. Takes one parameter and return true or false.

Let's talk about some use case of predicates -

1. Let's say we want to filter some data in a collection. We can provide a predicate which will take the input of collection and returns bool value.

e.g. - In WPF when we implement list view filtering. It is very useful

2. Some extension methods also take predicate as a parameter. e.g - List.FindAll(predicate)

Please have a look on implementation of predicate.

Hope you like reading the article. Please inbox me in case of any confusion.

Happy Coding :)
