示例1: Main
//引入命名空间
using System;
using System.Text;
class UnicodeEncodingExample {
public static void Main() {
Byte[] byteOrderMark;
byteOrderMark = Encoding.Unicode.GetPreamble();
Console.WriteLine("Default (little-endian) Unicode Preamble:");
foreach (Byte b in byteOrderMark) {
Console.Write("[{0}]", b);
}
Console.WriteLine("\n");
UnicodeEncoding bigEndianUnicode = new UnicodeEncoding(true, true);
byteOrderMark = bigEndianUnicode.GetPreamble();
Console.WriteLine("Big-endian Unicode Preamble:");
foreach (Byte b in byteOrderMark) {
Console.Write("[{0}]", b);
}
}
}示例2: Main
//引入命名空间
using System;
using System.IO;
using System.Text;
public class Example
{
public static void Main()
{
String s = "This is a string to write to a file using UTF-16 encoding.";
// Write a file using a Unicode encoding object without a BOM.
var enc = new UnicodeEncoding(! BitConverter.IsLittleEndian, false);
Byte[] bytes = enc.GetBytes(s);
WriteToFile(@".\NoPreamble.txt", enc, bytes);
// Use BOM.
enc = new UnicodeEncoding(! BitConverter.IsLittleEndian, true);
WriteToFile(@".\Preamble.txt", enc, bytes);
}
private static void WriteToFile(String fn, Encoding enc, Byte[] bytes)
{
var fs = new FileStream(fn, FileMode.Create);
Byte[] preamble = enc.GetPreamble();
fs.Write(preamble, 0, preamble.Length);
Console.WriteLine("Preamble has {0} bytes", preamble.Length);
fs.Write(bytes, 0, bytes.Length);
Console.WriteLine("Wrote {0} bytes to {1}.", fs.Length, fn);
fs.Close();
Console.WriteLine();
}
}输出：
Preamble has 0 bytes Wrote 116 bytes to .\NoPreamble.txt. Preamble has 2 bytes Wrote 118 bytes to .\Preamble.txt.
