Question

User339833461 posted

Hello Everyone,

I have 2 string arrays for example

string[] a = {"The","Big", "Ant", "The"};
string[] b = {"Big","Ant","Ran", "The"};

here i am comparing 2 string arrays(a may contains duplicate elements as well). How to get not matched elements while comparing a and b in b(with duplicates as well). in linq 'Except' i am not getting duplicate records. I need to get duplicates as well.

b = a.Except(b).ToArray();

Thanks

Try "Contains"

    string[] a = { "The", "Big", "Ant", "The" };
    string[] b = { "Big", "Ant", "Ran", "The" };

    var c = (from item in a
             where b.Contains(item)
             select item).ToArray(); // Get all "a" itens exist in "b"

    var d = (from item in a
             where b.Contains(item)
             select item).Distinct().ToArray(); // Get all "a" itens exist on "b" - distinct
