Encoding.Unicode Property

Gets an encoding for the UTF-16 format using the little-endian byte order.

Namespace:  System.Text
Assembly:  mscorlib (in mscorlib.dll)

public static Encoding Unicode { get; }

Property Value

Type: System.Text.Encoding
A Encoding for the UTF-16 format using the little-endian byte order.

For a discussion of little-endian byte order, see the Encoding class topic.

For information about the UTFs and other encodings supported by Unicode, see Understanding Encodings.

The following code example determines the number of bytes required to encode a character array, encodes the characters, and displays the resulting bytes.


using System;
using System.Text;

public class Example
{
   private static System.Windows.Controls.TextBlock outputBlock;

   public static void Demo(System.Windows.Controls.TextBlock outBlock)
   {
      outputBlock = outBlock;

      // The characters to encode:
      //    Latin Small Letter Z (U+007A)
      //    Latin Small Letter A (U+0061)
      //    Combining Breve (U+0306)
      //    Latin Small Letter AE With Acute (U+01FD)
      //    Greek Small Letter Beta (U+03B2)
      //    a high-surrogate value (U+D8FF)
      //    a low-surrogate value (U+DCFF)
      char[] myChars = new char[] { 'z', 'a', '\u0306', '\u01FD', '\u03B2', '\uD8FF', '\uDCFF' };

      // Get different encodings.
      Encoding u8 = Encoding.UTF8;
      Encoding u16LE = Encoding.Unicode;
      Encoding u16BE = Encoding.BigEndianUnicode;

      // Encode the entire array, and print out the counts and the resulting bytes.
      PrintCountsAndBytes(myChars, u8);
      PrintCountsAndBytes(myChars, u16LE);
      PrintCountsAndBytes(myChars, u16BE);
   }

   public static void PrintCountsAndBytes(char[] chars, Encoding enc)
   {
      // Display the name of the encoding used.
      outputBlock.Text += String.Format("{0,-30} :", enc.ToString());

      // Display the exact byte count.
      int iBC = enc.GetByteCount(chars);
      outputBlock.Text += String.Format(" {0,-3}", iBC);

      // Display the maximum byte count.
      int iMBC = enc.GetMaxByteCount(chars.Length);
      outputBlock.Text += String.Format(" {0,-3} :", iMBC);

      // Encode the array of chars.
      byte[] bytes = enc.GetBytes(chars);

      // Display all the encoded bytes.
      PrintHexBytes(bytes);
   }

   public static void PrintHexBytes(byte[] bytes)
   {
      if ((bytes == null) || (bytes.Length == 0))
         outputBlock.Text += "<none>" + "\n";
      else
      {
         for (int i = 0; i < bytes.Length; i++)
            outputBlock.Text += String.Format("{0:X2} ", bytes[i]);
         outputBlock.Text += "\n";
      }
   }
}
