I think this should do the trick

    string[] arr = { "red", "red", "blue", "green", "Black", "blue", "red" };

    var results = from str in arr
                  let c = arr.Count( m => str.Contains(m.Trim()))
                  select str + " count=" + str;

    foreach(string str in results.Distinct())
        Console.WriteLine(str);

Output:

red count=3
blue count=2
green count=1
Black count=1
