Hello,

Kindly run this code you will fully satisfied with this-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Please enter string");
string input = Convert.ToString(Console.ReadLine());
Dictionary<string, int> objdict = new Dictionary<string, int>();
foreach (char j in input)
{
if (objdict.ContainsKey(j.ToString()))
{
   objdict[j.ToString()] = objdict[j.ToString()] + 1;
}
else
{
   objdict.Add(j.ToString(), 1);
}
}
foreach (var temp in objdict)
{
   Console.WriteLine("Key: {0}, Value: {1}", temp.Key, temp.Value);
}
Console.ReadLine();
}

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
