public override int GetByteCount(
  char[] chars,//from   www  .  jav  a  2  s  .c o m
  int index,
  int count
)

Parameters

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

• chars - The character array containing the set of characters to encode.
• index - The index of the first character to encode.
• count - The number of characters to encode.

Returns

Example

/*from w  ww .j a v a2 s . c o m*/
using System;
using System.Text;

class UTF8EncodingExample {
    public static void Main() {
        Char[] chars = new Char[] {
            '\u0023', // #
            '\u0025', // %
            '\u03a0', // Pi
            '\u03a3'  // Sigma
        };

        UTF8Encoding utf8 = new UTF8Encoding();
        int byteCount = utf8.GetByteCount(chars, 1, 2);
        Console.WriteLine(byteCount);
    }
}

The code above generates the following result.
