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

Description

UTF8Encoding GetChars(Byte[], Int32, Int32, Char[], Int32) Decodes a sequence of bytes from the specified byte array into the specified character array.

Syntax

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

public override int GetChars(
  byte[] bytes,/*from w  w w  .  j  a va 2  s .co  m*/
  int byteIndex,
  int byteCount,
  char[] chars,
  int charIndex
)

Parameters

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

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

Returns

UTF8Encoding.GetChars(Byte[], Int32, Int32, Char[], Int32) method returns The actual number of characters written into chars.

Example

using System;/*  ww  w .  j  a v  a  2  s  .  c  o  m*/
using System.Text;

class UTF8EncodingExample
{
    public static void Main()
    {
        Char[] chars;
        Byte[] bytes = new Byte[] {69, 120,  97, 109, 112, 108, 101
        };

        UTF8Encoding utf8 = new UTF8Encoding();

        int charCount = utf8.GetCharCount(bytes, 2, 13);
        chars = new Char[charCount];
        int charsDecodedCount = utf8.GetChars(bytes, 2, 13, chars, 0);

        Console.WriteLine( charsDecodedCount);
        foreach (Char c in chars)
        {
            Console.Write("[{0}]", c);
        }
    }
}

The code above generates the following result.
