Program to find how many times a character repeated in a given string using C#

Suppose we have a string and we need to figure out how many characters have been repeated.The below code will help to do so

using System;
using System.Linq;
namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {            
            string lstWords = "hello this is dotnet funda"; 
            (from character in lstWords.ToCharArray().Where(x => !Char.IsWhiteSpace(x))
             group character by character into g
             select new
             {
                 Characters = g.Key,
                 RepeatedCharacters = (g.Count() - 1) == 0
                 ? String.Concat("Character ", g.Key, " has never repeated")
                  : String.Concat("Character ", g.Key, " repeated ", g.Count(), " times")
             }).ToList().ForEach(i => Console.WriteLine("{0} : {1}", i.Characters, i.RepeatedCharacters));
            Console.ReadKey(true);
        }
    }
}

Observe that we are removing the WhiteSpaces. Final output

h : Character h repeated 2 times
e : Character e repeated 2 times
l : Character l repeated 2 times
o : Character o repeated 2 times
t : Character t repeated 3 times
i : Character i repeated 2 times
s : Character s repeated 2 times
d : Character d repeated 2 times
n : Character n repeated 2 times
f : Character f has never repeated
u : Character u has never repeated
a : Character a has never repeated

Hope this will be helpful.
