Check if two List objects are equal in C#

To check if two List objects are equal, the code is as follows −

Example

 Live Demo

using System; using System.Collections.Generic; public class Demo {    public static void Main(String[] args){       List<string> list1 = new List<string>();       list1.Add("One");       list1.Add("Two");       list1.Add("Three");       list1.Add("Four");       list1.Add("Five");       Console.WriteLine("Elements in List1...");       foreach (string res in list1){          Console.WriteLine(res);       }       List<string> list2 = new List<string>();       list2.Add("India");       list2.Add("US");       list2.Add("UK");       list2.Add("Canada");       list2.Add("Poland");       list2.Add("Netherlands");       Console.WriteLine("Elements in List2...");       foreach (string res in list2){          Console.WriteLine(res);       }       Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1));    } }

Output

This will produce the following output −

Elements in List1... One Two Three Four Five Elements in List2... India US UK Canada Poland Netherlands Is List2 equal to List1? = False

Example

Let us see another example −

 Live Demo

using System; using System.Collections.Generic; public class Demo {    public static void Main(String[] args){       List<string> list1 = new List<string>();       list1.Add("One");       list1.Add("Two");       list1.Add("Three");       list1.Add("Four");       list1.Add("Five");       Console.WriteLine("Elements in List1...");       foreach (string res in list1){          Console.WriteLine(res);       }       List<string> list2 = new List<string>();       list2.Add("India");       list2.Add("US");       list2.Add("UK");       list2.Add("Canada");       list2.Add("Poland");       list2.Add("Netherlands");       Console.WriteLine("Elements in List2...");       foreach (string res in list2){          Console.WriteLine(res);       }       List<string> list3 = new List<string>();       list3 = list2;       Console.WriteLine("Is List3 equals to List2? = "+list3.Equals(list2));    } }

Output

This will produce the following output −

Elements in List1... One Two Three Four Five Elements in List2... India US UK Canada Poland Netherlands Is List3 equals to List2? = True
