Hi Soumya, Please find the below link for your reference: http://www.c-sharpcorner.com/Blogs/15703/ And also You can count all char of a string in two way. 1.Including Space of a string like public int CountStringChars(string inputStringText) { int resultCount = 0; bool isWhiteSpace = false; foreach (char c in inputStringText) { if (char.IsWhiteSpace(c)) { if (isWhiteSpace == false) { resultCount++; } isWhiteSpace = true; } else { resultCount++; isWhiteSpace = false; } } return resultCount; } and 2.Count char in a string Without space public int CountNonSpaceChars(string inputStringText) { int resultCount = 0; foreach (char c in inputStringText) { if (!char.IsWhiteSpace(c)) { resultCount++; } } return resultCount; }

Hi, Try this code : string inputString = "sowmya velaga"; inputString = inputString.Replace(" ", ""); char[] uniqueChars = inputString.Distinct().ToArray(); foreach (char uniquechar in uniqueChars) { int stringCount = inputString.Replace(uniquechar.ToString(), "").Length; Console.WriteLine("Count Of " + uniquechar + " in " + inputString + " is " + (inputString.Length - stringCount).ToString()); } You will get output like this : Count Of s in sowmyavelaga is 1 Count Of o in sowmyavelaga is 1 Count Of w in sowmyavelaga is 1 Count Of m in sowmyavelaga is 1 Count Of y in sowmyavelaga is 1 Count Of a in sowmyavelaga is 3 Count Of v in sowmyavelaga is 1 Count Of e in sowmyavelaga is 1 Count Of l in sowmyavelaga is 1 Count Of g in sowmyavelaga is 1
