示例1: Main
//引入命名空間
using System;
using System.Text;
class UTF8EncodingExample {
public static void Main() {
UTF8Encoding utf8 = new UTF8Encoding();
String encodingName = utf8.EncodingName;
Console.WriteLine("Encoding name: " + encodingName);
}
}示例2: Main
//引入命名空間
using System;
using System.Text;
class UTF8EncodingExample {
public static void Main() {
UTF8Encoding utf8 = new UTF8Encoding();
UTF8Encoding utf8EmitBOM = new UTF8Encoding(true);
Console.WriteLine("utf8 preamble:");
ShowArray(utf8.GetPreamble());
Console.WriteLine("utf8EmitBOM:");
ShowArray(utf8EmitBOM.GetPreamble());
}
public static void ShowArray(Array theArray) {
foreach (Object o in theArray) {
Console.Write("[{0}]", o);
}
Console.WriteLine();
}
}示例3: Main
//引入命名空間
using System;
using System.Text;
class Example
{
public static void Main()
{
UTF8Encoding utf8 = new UTF8Encoding();
UTF8Encoding utf8ThrowException = new UTF8Encoding(false, true);
// Create an array with two high surrogates in a row (\uD801, \uD802).
Char[] chars = new Char[] {'a', 'b', 'c', '\uD801', '\uD802', 'd'};
// The following method call will not throw an exception.
Byte[] bytes = utf8.GetBytes(chars);
ShowArray(bytes);
Console.WriteLine();
try {
// The following method call will throw an exception.
bytes = utf8ThrowException.GetBytes(chars);
ShowArray(bytes);
}
catch (EncoderFallbackException e) {
Console.WriteLine("{0} exception\nMessage:\n{1}",
e.GetType().Name, e.Message);
}
}
public static void ShowArray(Array theArray) {
foreach (Object o in theArray)
Console.Write("{0:X2} ", o);
Console.WriteLine();
}
}輸出：
