using System;
using System.Text;
public class SamplesEncoding {
public static void Main() {
// Create two instances of UTF32Encoding: one with little-endian byte order and one with big-endian byte order.
Encoding u32LE = Encoding.GetEncoding( "utf-32" );

// Use a string containing the following characters:
// 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)
String myStr = "za\u0306\u01FD\u03B2";
// Encode the string using the big-endian byte order.
byte[] barrBE = new byte[u32BE.GetByteCount( myStr )];
u32BE.GetBytes( myStr, 0, myStr.Length, barrBE, 0 );

// Get the char counts, decode eight bytes starting at index 0,
// and print out the counts and the resulting bytes.

PrintCountsAndChars( barrBE, 0, 8, u32BE );
Console.Write( "LE array with LE encoding : " );

// Display the name of the encoding used.

int iMCC = enc.GetMaxCharCount( count );

char[] chars = enc.GetChars( bytes, index, count );
// The following is an alternative way to decode the bytes:
// char[] chars = new char[iCC];
// enc.GetChars( bytes, index, count, chars, 0 );

This code produces the following output. The question marks take the place of characters that cannot be displayed at the console.
