Difference between Delegate, Function and Predicates

Delegates

• A delegate is a method with a parameter and a return type.
• A delegate is a type that safely encapsulates a method.
• Delegates are object-oriented, type safe, and secure.

Special Notes

 

               We can’t derive a custom class from the delegates because it is sealed.

Functions:

               A function allows you to encapsulate a piece of code and call it from the other parts of your code.

Predicate:

• Predicate is a functional construct, providing a convenient way of basically testing if something is true of a given T object.
• Predicates are simply delegates that returns booleans.
• They're useful when you're searching through a collection of objects and want something specific.
