UnicodeEncoding 类

下面的示例演示如何使用 UnicodeEncoding 将 Unicode 字符串编码为字节数组。然后将该字节数组解码为字符串，以表明没有丢失数据。

 

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);
    }
}

在控制台运行结果：
