Convert byte array to String with BitConverter

<source lang="csharp">

using System; using System.IO; using System.Text; class MainClass {

   public static void Main()
   {
       using (StreamWriter output = new StreamWriter("output.txt"))
       {
           string srcString = "Area = \u03A0r^2";
           output.WriteLine("Source Text : " + srcString);
           byte[] utf16String = Encoding.Unicode.GetBytes(srcString);
           output.WriteLine("UTF-16 Bytes: {0}",BitConverter.ToString(utf16String)); 
           byte[] utf8String = Encoding.UTF8.GetBytes(srcString);
           byte[] asciiString = Encoding.ASCII.GetBytes(srcString);
           output.WriteLine("UTF-8 Bytes: {0}",
           BitConverter.ToString(utf8String));
           output.WriteLine("ASCII Bytes: {0}",
           BitConverter.ToString(asciiString));
           output.WriteLine("UTF-8 Text : {0}",Encoding.UTF8.GetString(utf8String));
