How to iterate two Lists or Arrays with one foreach statement in C#?
Set two arrays.
var val = new [] { 20, 40, 60}; var str = new [] { "ele1", "ele2", "ele3"};
Use the zip() method to process the two arrays in parallel.
var res = val.Zip(str, (n, w) => new { Number = n, Word = w });
The above fetches both the arrays with int and string elements respectively.
Now, use foreach to iterate the two arrays −
Example
using System; using System.Collections.Generic; using System.Linq; public class Demo { public static void Main() { var val = new [] { 20, 40, 60}; var str = new [] { "ele1", "ele2", "ele3"}; var res = val.Zip(str, (n, w) => new { Number = n, Word = w }); foreach(var a in res) { Console.WriteLine(a.Number + a.Word); } } }
Output
20ele1 40ele2 60ele3
