What are named and optional parameters in c# 4.0?

Hi guys

 This article we will explain what is the new c# features named and optional parameters

Named and optional parameters available in c # 4.0 version. Now we discuss what is named.

Named:-

Named parameter a developer can skip parameters that have default values and named only the parameters that have non-default values.

Optional parameters:-

It gives scope us to declare a default value to method parameter. So we don’t need to define it every time when we call the method.

Example:-

Public class A

{

Public static void  callme(string name= “Sanjib”, string city =”New Delhi”, int  id)

{}

Static void main(string[] args)

{

Method(100); // result of return method is(“Sanjib” ,”New Delhi”,100)
