Set three lists −
// three lists var list1 = new List<int>{3, 4}; var list2 = new List<int>{1, 2, 3}; var list3 = new List<int>{2, 5, 6};
Now, use the Concat mthod to concat the above lists −
var res1 = list1.Concat(list2); var res2 = res1.Concat(list3);
Here is the complete code −
using System.Collections.Generic; using System.Linq; using System; public class Demo { public static void Main() { // three lists var list1 = new List<int>{3, 4}; var list2 = new List<int>{1, 2, 3}; var list3 = new List<int>{2, 5, 6}; // concat var res1 = list1.Concat(list2); var res2 = res1.Concat(list3); foreach(int i in res2) { Console.WriteLine(i); } } }
3 4 1 2 3 2 5 6
