Add auto complete function for a textbox in your winform

auto complete is useful in a winform to, for example, help user to save time for type things such as username, to add auto listing to a textbox in a winform is very easy, below is an example code added to the Load delegate method in a winform:

            List<string> usernames = AccountManager.Instance.Usernames;
            if (usernames.Count > 0)
                var source = new AutoCompleteStringCollection();
                foreach (string username in usernames)

                txtUsername.AutoCompleteCustomSource = source;
                txtUsername.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                txtUsername.AutoCompleteSource = AutoCompleteSource.CustomSource;
