Zip method in C# in an interesting extension method that lets the developers to join together two array sequences (IEnumerable). It just processes each element in the 2 IEnumerable collections together.
Assume that you have two arrays of 3 elements each and you wish to show the sum of each index values of the source arrays , you can use the zip extension method in C# as shows below.
using System;
using System.Linq;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
var arr1 = new int[] { 5 , 6 , 3 };
var arr2 = new int[] { 5 , 8 , 2};
var combinedArray = arr1.Zip(arr2, (val1, val2) => (val1 + val2));
foreach (var indexVal in combinedArray)
{
Console.WriteLine(indexVal);
}
Console.ReadLine();
}
}
}Output
