How to join two lists in C#?
To join two lists, use AddRange() method.
Set the first list −
var list1 = new List < string > ();
list1.Add("Keyboard");
list1.Add("Mouse");

var list2 = new List < string > ();
list2.Add("Hard Disk");
list2.Add("Pen Drive");
To concatenate both the lists −
lists1.AddRange(lists2);
The following is the complete code −

using System.Collections.Generic;
using System;
namespace Demo {
public static class Program {
public static void Main() {
var list1 = new List < string > ();
list1.Add("Keyboard");
list1.Add("Mouse");
Console.WriteLine("Our list1....");
foreach(var p in list1) {
Console.WriteLine(p);
}
var list2 = new List < string > ();
list2.Add("Hard Disk");
list2.Add("Pen Drive");
Console.WriteLine("Our list2....");
foreach(var p in list2) {
Console.WriteLine(p);
}
list1.AddRange(list2);
Console.WriteLine("Concatenated list....");
foreach(var p in list1) {
Console.WriteLine(p);
