Here's one way to do it:

using System;
using System.Text;
using System.Collections.Generic;

class Program
{
static void Main()
{
string str="aabcbbcdccd";
var sd = new SortedDictionary();

foreach(char c in str)
{
if (sd.ContainsKey(c))
{
sd[c]++;
}
else
{
sd.Add(c, 1);
}
}

var sb = new StringBuilder();

foreach(char c in sd.Keys)
{
sb.Append(c);
sb.Append(sd[c].ToString());
}

string str2 = sb.ToString();
Console.WriteLine(str2); // a2b3c4d2
Console.ReadKey();
}
}
