C# UTF8Encoding GetBytes(Char[], Int32, Int32)
Description
UTF8Encoding GetBytes(Char[], Int32, Int32) When overridden
in a derived class, encodes a set of characters from the specified character
array into a sequence of bytes.
Syntax
UTF8Encoding.GetBytes(Char[], Int32, Int32) has the following syntax.
public virtual byte[] GetBytes(
char[] chars,//from ww w . j a v a2 s .c om
int index,
int count
)
Parameters
UTF8Encoding.GetBytes(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
UTF8Encoding.GetBytes(Char[], Int32, Int32) method returns
Example
//from w w w . j a va 2 s .c o m
using System;
using System.Text;
public class SamplesEncoding {
public static void Main() {
char[] myChars = new char[] { 'z', 'a', '\u0306', '\u01FD', '\u03B2', '\uD8FF', '\uDCFF' };
Encoding u8 = Encoding.UTF8;
PrintCountsAndBytes( myChars, 4, 3, u8 );
}
public static void PrintCountsAndBytes( char[] chars, int index, int count, Encoding enc ) {
byte[] bytes = enc.GetBytes( chars, index, count );
if (( bytes == null ) || ( bytes.Length == 0 ))
Console.WriteLine( "<none>" );
else {
for ( int i = 0; i < bytes.Length; i++ )
Console.Write( "{0:X2} ", bytes[i] );
Console.WriteLine();
}
}
}
The code above generates the following result.
