As a complement to the already posted answers, here is a solution without using the Zip method. This assumes that both arrays is of same length.

        var pairs = from idx in Enumerable.Range(0, title.Length)
                    let pair = new {Title = title[idx], User = user[idx]}
                    where !String.IsNullOrEmpty(pair.User)
                    select String.Format("{0}:{1}", pair.Title, pair.User);
