CSharp - Method params modifier

Introduction

The params parameter modifier can be added to the last parameter of a method.

Method with params parameter accepts any number of arguments of a particular type.

The parameter type must be declared as an array.

For example:

Demo

using System;
class Test/*from w ww  .ja  v a  2 s.co  m*/
{
       static int Sum (params int[] ints)
       {
         int sum = 0;
         for (int i = 0; i < ints.Length; i++){
              sum += ints[i];                    
         }  
         return sum;
       }

       static void Main()
       {
         int total = Sum (1, 2, 3, 4);
         Console.WriteLine (total);              // 10
       }
}

Result

You can use a params argument as an ordinary array.

int total = Sum (new int[] { 1, 2, 3, 4 } );
