Compare the difference between two list

Question

I\'am trying to check the difference between two List in c#.

Example:

List FirstList = new List         


        

Answer 1

Try to use Except LINQ extension method, which takes items only from the first list, that are not present in the second. Example is given below:

List ThirdList =  SecondList.Except(FirstList).ToList();

You can print the result using the following code:

Console.WriteLine(string.Join(Environment.NewLine, ThirdList));

Or

Debug.WriteLine(string.Join(Environment.NewLine, ThirdList));

Note: Don't forget to include: using System.Diagnostics;

prints:
