示例1: Main
//引入命名空间
using System;
using System.Text;
class UnicodeEncodingExample {
public static void Main() {
// The encoding.
UnicodeEncoding unicode = new UnicodeEncoding();
// Create a string that contains Unicode characters.
String unicodeString =
"This Unicode string contains two characters " +
"with codes outside the traditional ASCII code range, " +
"Pi (\u03a0) and Sigma (\u03a3).";
Console.WriteLine("Original string:");
Console.WriteLine(unicodeString);
// Encode the string.
Byte[] encodedBytes = unicode.GetBytes(unicodeString);
Console.WriteLine();
Console.WriteLine("Encoded bytes:");
foreach (Byte b in encodedBytes) {
Console.Write("[{0}]", b);
}
Console.WriteLine();
// Decode bytes back to string.
// Notice Pi and Sigma characters are still present.
String decodedString = unicode.GetString(encodedBytes);
Console.WriteLine();
Console.WriteLine("Decoded bytes:");
Console.WriteLine(decodedString);
}
}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()
{
// Create a UTF-16 encoding that supports a BOM.
Encoding unicode = new UnicodeEncoding();
// A Unicode string with two characters outside an 8-bit code range.
String unicodeString =
"This Unicode string has 2 characters outside the " +
"ASCII range: \n" +
"Pi (\u03A0)), and Sigma (\u03A3).";
Console.WriteLine("Original string:");
Console.WriteLine(unicodeString);
Console.WriteLine();
// Encode the string.
Byte[] encodedBytes = unicode.GetBytes(unicodeString);
Console.WriteLine("The encoded string has {0} bytes.\n",
encodedBytes.Length);
// Write the bytes to a file with a BOM.
var fs = new FileStream(@".\UTF8Encoding.txt", FileMode.Create);
Byte[] bom = unicode.GetPreamble();
fs.Write(bom, 0, bom.Length);
fs.Write(encodedBytes, 0, encodedBytes.Length);
Console.WriteLine("Wrote {0} bytes to the file.\n", fs.Length);
fs.Close();
// Open the file using StreamReader.
var sr = new StreamReader(@".\UTF8Encoding.txt");
String newString = sr.ReadToEnd();
sr.Close();
Console.WriteLine("String read using StreamReader:");
Console.WriteLine(newString);
Console.WriteLine();
// Open the file as a binary file and decode the bytes back to a string.
fs = new FileStream(@".\UTF8Encoding.txt", FileMode.Open);
Byte[] bytes = new Byte[fs.Length];
fs.Read(bytes, 0, (int)fs.Length);
fs.Close();
String decodedString = unicode.GetString(bytes);
Console.WriteLine("Decoded bytes:");
Console.WriteLine(decodedString);
}
}输出：
Original string: This Unicode string has 2 characters outside the ASCII range: Pi (π), and Sigma (Σ). The encoded string has 172 bytes. Wrote 174 bytes to the file. String read using StreamReader: This Unicode string has 2 characters outside the ASCII range: Pi (π), and Sigma (Σ). Decoded bytes: This Unicode string has 2 characters outside the ASCII range: Pi (π), and Sigma (Σ).
