C# UTF8Encoding GetBytes(Char[], Int32, Int32, Byte[], Int32)

Description

UTF8Encoding GetBytes(Char[], Int32, Int32, Byte[], Int32) Encodes a set of characters from the specified character array into the specified byte array.

Syntax

UTF8Encoding.GetBytes(Char[], Int32, Int32, Byte[], Int32) has the following syntax.

public override int GetBytes(
  char[] chars,/*from   w w w .  j  a v  a2  s  . c om*/
  int charIndex,
  int charCount,
  byte[] bytes,
  int byteIndex
)

Parameters

UTF8Encoding.GetBytes(Char[], Int32, Int32, Byte[], Int32) has the following parameters.

• chars - The character array containing the set of characters to encode.
• charIndex - The index of the first character to encode.
• charCount - The number of characters to encode.
• bytes - The byte array to contain the resulting sequence of bytes.
• byteIndex - The index at which to start writing the resulting sequence of bytes.

Returns

UTF8Encoding.GetBytes(Char[], Int32, Int32, Byte[], Int32) method returns The actual number of bytes written into bytes.

Example

using System;/*w  w  w .ja  v  a 2 s .  co  m*/
using System.Text;

class UTF8EncodingExample {
    public static void Main() {
        Byte[] bytes;
        String chars = "UTF8 Encoding Example";

        UTF8Encoding utf8 = new UTF8Encoding();

        int byteCount = utf8.GetByteCount(chars.ToCharArray(), 0, 13);
        bytes = new Byte[byteCount];
        int bytesEncodedCount = utf8.GetBytes(chars, 0, 13, bytes, 0);

        Console.WriteLine(bytesEncodedCount);

        foreach (Byte b in bytes) {
            Console.WriteLine("[{0}]", b);
        }
    }
}

The code above generates the following result.
