Example

The following example demonstrates using the System.Text.UTF8Encoding implementation of the System.Text.Decoder class to convert two byte arrays to a character array, where one character's bytes span multiple byte arrays. This demonstrates how to use a System.Text.Decoder in streaming-like situations.

using System;
using System.Text;
namespace Samples
{
  public class DecoderSample
  {
    public static void Main()
    {
      byte[] b1 = { 0x41, 0x23, 0xe2 };
      byte[] b2 = { 0x98, 0xa3 };
      Decoder d = Encoding.UTF8.GetDecoder();
      char[] chars = new char[3];
      int i = d.GetChars(b1, 0, b1.Length, chars, 0);
      i += d.GetChars(b2, 0, b2.Length, chars, i);
      foreach(char c in chars)
        Console.Write("U+{0:x} ", (ushort)c);
    }
  }
}

The output is

U+41 U+23 U+2623
