Is there any way to search an arraylist storing a line as a string?

  • 0

Is there any way to search an arraylist storing a line as a string? I want to search by the first word in every line stored in the arraylist. I tried doing the Arraylist.Contains() and Arraylist.IndexOf but those do not seem to be working? Anyone have any suggestions?

Thanks

    string[] matches = arrayList.Cast<string>()
                                .Where(i => i.StartsWith(searchTerm)).ToArray();
