示例1: Main
//引入命名空间
using System;
using System.Text;
class EncoderTest {
public static void Main() {
// The characters to encode.
Char[] chars = new Char[] {
'\u0023', // #
'\u0025', // %
'\u03a0', // Pi
'\u03a3' // Sigma
};
// Encode characters using an Encoding object.
Encoding encoding = Encoding.UTF7;
Console.WriteLine("Using Encoding\n--------------");
// Encode complete array for comparison.
Byte[] allCharactersFromEncoding = encoding.GetBytes(chars);
Console.WriteLine("All characters encoded:");
ShowArray(allCharactersFromEncoding);
// Encode characters, one-by-one.
// The Encoding object will NOT maintain state between calls.
Byte[] firstchar = encoding.GetBytes(chars, 0, 1);
Console.WriteLine("First character:");
ShowArray(firstchar);
Byte[] secondchar = encoding.GetBytes(chars, 1, 1);
Console.WriteLine("Second character:");
ShowArray(secondchar);
Byte[] thirdchar = encoding.GetBytes(chars, 2, 1);
Console.WriteLine("Third character:");
ShowArray(thirdchar);
Byte[] fourthchar = encoding.GetBytes(chars, 3, 1);
Console.WriteLine("Fourth character:");
ShowArray(fourthchar);
// Now, encode characters using an Encoder object.
Encoder encoder = encoding.GetEncoder();
Console.WriteLine("Using Encoder\n-------------");
// Encode complete array for comparison.
Byte[] allCharactersFromEncoder = new Byte[encoder.GetByteCount(chars, 0, chars.Length, true)];
encoder.GetBytes(chars, 0, chars.Length, allCharactersFromEncoder, 0, true);
Console.WriteLine("All characters encoded:");
ShowArray(allCharactersFromEncoder);
// Do not flush state; i.e. maintain state between calls.
bool bFlushState = false;
// Encode characters one-by-one.
// By maintaining state, the Encoder will not store extra bytes in the output.
Byte[] firstcharNoFlush = new Byte[encoder.GetByteCount(chars, 0, 1, bFlushState)];
encoder.GetBytes(chars, 0, 1, firstcharNoFlush, 0, bFlushState);
Console.WriteLine("First character:");
ShowArray(firstcharNoFlush);
Byte[] secondcharNoFlush = new Byte[encoder.GetByteCount(chars, 1, 1, bFlushState)];
encoder.GetBytes(chars, 1, 1, secondcharNoFlush, 0, bFlushState);
Console.WriteLine("Second character:");
ShowArray(secondcharNoFlush);
Byte[] thirdcharNoFlush = new Byte[encoder.GetByteCount(chars, 2, 1, bFlushState)];
encoder.GetBytes(chars, 2, 1, thirdcharNoFlush, 0, bFlushState);
Console.WriteLine("Third character:");
ShowArray(thirdcharNoFlush);
// Must flush state on last call to GetBytes().
bFlushState = true;
Byte[] fourthcharNoFlush = new Byte[encoder.GetByteCount(chars, 3, 1, bFlushState)];
encoder.GetBytes(chars, 3, 1, fourthcharNoFlush, 0, bFlushState);
Console.WriteLine("Fourth character:");
ShowArray(fourthcharNoFlush);
}
public static void ShowArray(Array theArray) {
foreach (Object o in theArray) {
Console.Write("[{0}]", o);
}
Console.WriteLine("\n");
}
}输出：
