示例1: Main
//引入命名空间
using System;
using System.Text;
class UTF8EncodingExample {
public static void Main() {
String chars = "UTF8 Encoding Example";
Encoding utf8 = Encoding.UTF8;
Console.WriteLine("Bytes needed to encode '{0}':", chars);
Console.WriteLine(" Maximum: {0}",
utf8.GetMaxByteCount(chars.Length));
Console.WriteLine(" Actual: {0}",
utf8.GetByteCount(chars));
Console.WriteLine(" Actual with BOM: {0}",
utf8.GetByteCount(chars) + utf8.GetPreamble().Length);
}
}输出：
Bytes needed to encode 'UTF8 Encoding Example': Maximum: 66 Actual: 21 Actual with BOM: 24
示例2: Main
//引入命名空间
using System;
using System.Text;
public class Example
{
public static void Main()
{
int uppercaseStart = 0x0041;
int uppercaseEnd = 0x005a;
int lowercaseStart = 0x0061;
int lowercaseEnd = 0x007a;
// Instantiate a UTF8 encoding object with BOM support.
Encoding utf8 = new UTF8Encoding(true);
// Populate array with characters.
char[] chars = new char[lowercaseEnd - lowercaseStart + uppercaseEnd - uppercaseStart + 2];
int index = 0;
for (int ctr = uppercaseStart; ctr <= uppercaseEnd; ctr++) {
chars[index] = (char)ctr;
index++;
}
for (int ctr = lowercaseStart; ctr <= lowercaseEnd; ctr++) {
chars[index] = (char)ctr;
index++;
}
// Display the bytes needed for the lowercase characters.
Console.WriteLine("Bytes needed for lowercase Latin characters:");
Console.WriteLine(" Maximum: {0,5:N0}",
utf8.GetMaxByteCount(lowercaseEnd - lowercaseStart + 1));
Console.WriteLine(" Actual: {0,5:N0}",
utf8.GetByteCount(chars, uppercaseEnd - uppercaseStart + 1,
lowercaseEnd - lowercaseStart + 1));
Console.WriteLine(" Actual with BOM: {0,5:N0}",
utf8.GetByteCount(chars, uppercaseEnd - uppercaseStart + 1,
lowercaseEnd - lowercaseStart + 1) +
utf8.GetPreamble().Length);
}
}输出：
Bytes needed for lowercase Latin characters: Maximum: 81 Actual: 26 Actual with BOM: 29
