selecting distinct elements from two lists using LINQ?

Question

List<int> lst1 = new List<int>{1,2,3,5,2};
List<int> lst2 = new List<int>{4,5,6,1,6};
List<int> lst3 = new List<int>();

Expected Output: lst3={1,2,3,4,5,6}

Can anyone help me with the LINQ code to select distinct elements from two lists ?

Thank you

Use the Union() method, which produces the Set Union of two lists, returning a new list containing all the items that exist in both lists:

lst3 = list1.Union(lst2).OrderBy(p=>p).ToList();
