C# Named and Optional Arguments Tutorial with Examples
Today, We want to share with you C# Named and Optional Arguments Tutorial with Examples.
In this post we will show you Optional Arguments In C#, hear for Optional Parameters and Named Arguments in C# Example we will give you demo and example for implement.
In this post, we will learn about Named and optional parameters in C# with an example.
Introduction: Optional Arguments In C#
In this post, we will learn about Optional Arguments In C#. An optional parameter has a default value.
Now in this post, I will explain about Optional Arguments In C# with appropriate example.By using this new feature in C#.Net , we can add default values for formal parameters.There can be any number of Optional Arguments in a method.Optional Arguments are defined at the end of the parameter list in method.
Example:
Create Console Application in Visual Studio and write below lines of codes in it.
using System;
using System.Collections;
namespace ConsoleDemo
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("pakainfo.Com");
///Call the method by omiting Optional Arguments
Program.GetDetails(1, "Raj");
///Call the method by omiting 'course' Optional Arguments
Program.GetDetails(2, "Mahesh", 11);
///Call the method with all the parameters that will override the default values
Program.GetDetails(3, "Pinak", 12, "Science");
Console.ReadLine();
}
public static void GetDetails(int roll_No, string name, int id = 10, string course = "Btech")
{
Console.WriteLine(string.Format("Roll No.: {0}, Name: {1}, id: {2}, Course: {3}", roll_No, name, id, course));
}
}
}
