Compare two List<string> using LINQ

In this post, we will see how to compare two List<string> and list the elements found in one List<string> but not in the other. We will be using the Enumerable.Except method


static void Main(string[] args)
List<string> lstOne =
new List<string>() { "Jim", "Jack", "Kate", "Nope" };

List<string> lstTwo =
new List<string>() { "Jack", "Nope", "Jim" };

IEnumerable<string> lstNew = null;

// Compare two List<string> and display items of lstOne not in lstTwo
lstNew = lstOne.Except(lstTwo, StringComparer.OrdinalIgnoreCase);


static void PrintList(IEnumerable<string> str)
foreach (var s in str)
