Hi Nitesh,

Try this code,

string Word;
Console.WriteLine("Enter the word!..");
Word = Console.ReadLine();
var Value = Word;
Dictionary<string, int> RepeatedWordCount = new Dictionary<string, int>();
for (int i = 0; i < Value.Length; i++) //loop the splited string
{
if (RepeatedWordCount.ContainsKey(Convert.ToString(Value[i]))) // Check if word already exist in dictionary update the count
{
int value = RepeatedWordCount[Convert.ToString(Value[i])];
RepeatedWordCount[Convert.ToString(Value[i])] = value + 1;
}
else
{
RepeatedWordCount.Add(Convert.ToString(Value[i]), 1); // if a string is repeated and not added in dictionary , here we are adding
}
}
Console.WriteLine();
Console.WriteLine("------------------------------------");
Console.WriteLine("Repeated words and counts");
foreach (KeyValuePair<string, int> kvp in RepeatedWordCount)
{
Console.WriteLine(kvp.Key + " Counts are " + kvp.Value); // Print the Repeated word and its count
}
Console.ReadKey();
