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");
Set the second list −
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 −
Example
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); } } } }
