Defined:A delegate is a type that holds a reference to a method in an object and is also a type-safe function pointer.One way to understand a delegate is to think of the role of a delegate as specifying a name for the method signature.The definition

A random number is defined as: All the numbers produced have no relation.Random numbers are used in many places in real-world applications, such as the need to generate unique order numbers.There are three ways to get a random number in C #:A.
