Question

I have a List item

List<string> xmlValue = new List<string>();

In this I have Item {"English","Spanish","French","Hindi","English","English"}
I need to search all English item along with its Index(item index).
I wrote the below code it returns index only for 1 item .How can get the index for the next item also.

    string search = "English";
    int index = xmlValue.Select((item, i) => new { Item = item, Index = i })
    .First(x => x.Item == search).Index;

Answer 1

List<string> xmlValue = new List<string>() 
                 {"English", "Spanish", "French", "Hindi", "English", "English"};

string search = "English";

int[] result = xmlValue.Select((b, i) => b.Equals(search) ? i : -1)
                       .Where(i => i != -1).ToArray();
