Find Subarray From Array in C# 4.5

Introduction

In this article I explain how to select a subarray from an array. However there are several ways to fetch a subarray from an array. Here I describe a very simple and easy way to select a subarray from an array using the built-in method to copy an array.

Use this simple procedure to get a subarray from an array.

Step 1

Open a console application and write the following simple code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

 

namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {

          int[] arr={12,45,78,36,97,85,45,68,25,30,78};  

            int[] arr2=new int[5];

            Array .Copy (arr,2,arr2,0,5);

            foreach (int a in arr2 )

            {

                Console .Write (a +  " ");

            }

            Console.Read();

         }

        }

    }

 

Step 2

Now run your application and see the output.
