From http://msdn.microsoft.com/en-us/library/system.text.encoding.convert%28VS.71%29.aspx

string value = "9quali52ty3";

// Convert the string into a byte[].
byte[] asciiBytes = Encoding.ASCII.GetBytes(value);

Try this and let me know.

ascii to string

string str = char.ConvertFromUtf32(65)

protected void Page_Load(object sender, EventArgs e)
{
  string s = "hello";
  StringBuilder result = new StringBuilder();
  foreach (char c in s)
  {
    if (Char.IsLetter(c))
    {
      string str = System.Convert.ToInt32(c).ToString() + " ";        
      result.Append(str);
    }      
  }
  Response.Write("Result:" + result);

Use this code-

using System;
using System.Text;

namespace ConvertExample
{
   class ConvertExampleClass
   {
    static void Main()
    {
     string unicodeString = "This string contains the unicode character Pi(\u03a0)";

     // Create two different encodings.
       Encoding ascii = Encoding.ASCII;
     Encoding unicode = Encoding.Unicode;

       // Convert the string into a byte[].
     byte[] unicodeBytes = unicode.GetBytes(unicodeString);

     // Perform the conversion from one encoding to the other.
     byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);

       // Convert the new byte[] into a char[] and then into a string.
     // This is a slightly different approach to converting to illustrate
     // the use of GetCharCount/GetChars.
     char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
     ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
     string asciiString = new string(asciiChars);

       // Display the strings created before and after the conversion.
     Console.WriteLine("Original string: {0}", unicodeString);
     Console.WriteLine("Ascii converted string: {0}", asciiString);
    }
   }
}

Hope this code will help you.
