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
