namespace AsciiEncodingDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            ASCIIEncoding myAscii = new ASCIIEncoding();
            string unicodeStr = "ASCII Encoding Demo";
            Console.WriteLine(unicodeStr);
            //下面的代码将对unicodeStr字符串的内容进行编码。
            Byte[] encodeBytes = myAscii.GetBytes(unicodeStr);
            Console.WriteLine("编码后的字符串：");
            foreach (byte c in encodeBytes)
            {
                Console.Write("[{0}]", c);
            }
            Console.WriteLine("");
            Console.WriteLine("解码后的字符串：");
            //下面的语句将对encodeBytes字节数组的内容进行解码
            string decodeStr = myAscii.GetString(encodeBytes);
            Console.WriteLine(decodeStr);
            Console.ReadLine();        
         }
    }
