The following code example converts a string from one encoding to another.


using System;
using System.Text;

class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      string unicodeString = "This string contains the unicode character Pi (\u03a0)";

      // Create two different encodings.
      Encoding utf8 = Encoding.UTF8;
      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[] utf8Bytes = Encoding.Convert(unicode, utf8, unicodeBytes);

      // Convert the new byte[] into a char[] and then into a string.
      char[] utf8Chars = new char[utf8.GetCharCount(utf8Bytes, 0, utf8Bytes.Length)];
      utf8.GetChars(utf8Bytes, 0, utf8Bytes.Length, utf8Chars, 0);
      string utf8String = new string(utf8Chars);

      // Display the strings created before and after the conversion.
      outputBlock.Text += String.Format("Original string: {0}", unicodeString) + "\n";
      outputBlock.Text += String.Format("Ascii converted string: {0}", utf8String) + "\n";
   }
}
// The example displays the following output:
//    Original string: This string contains the unicode character Pi (Π)
//    Ascii converted string: This string contains the unicode character Pi (?)
