大家好!!
    是一个关于加密的算法,我在VC++6.0中编译始终出现4个错误,而且原程序我也看不懂,请所有的高手帮帮看看问题出现在什么地方,怎么解决??谢谢!!
                    


原程序:


/// 密钥字符串:27jrWz2sxrVbR+pnyg6jWHhgNk4sZo46
/// 要加密的字符串:3033$13311083060$D10$2004-02-24 16:19:27
/// 加密后的字符串:KoewfwcFjuBwlzVOh5UOU3FU/8weXQd9B1RoLeVS3UCp9aVfQuivfSTrJofn/7d9  [STAThread]
     
static void main(string[] args)
{
    
    string key = "27jrWz2sxrVbR+pnyg6jWHhgNk4sZo46";   //密钥字符串
    
    byte[] keybytes = Convert.FromBase64String(key);
    
    string src = "3033$13311083060$D10$2004-02-24 16:19:27";
    
    byte[] srcbyte = Encoding.ASCII.GetBytes(src);
    
    TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
    
    tdes.Mode =  CipherMode.ECB;
    
    tdes.Key = keybytes;
    
    tdes.Padding = PaddingMode.PKCS7;
    
    MemoryStream fout = new System.IO.MemoryStream(80);
    
    MemoryStream fin = new System.IO.MemoryStream(80);
    
    CryptoStream encStream = new CryptoStream(fout, tdes.CreateEncryptor(), CryptoStreamMode.Write);
    
    encStream.Write(srcbyte,0,srcbyte.Length);
    
    encStream.FlushFinalBlock();
    
    CryptoStream deStream = new CryptoStream(fin,tdes.CreateDecryptor(),CryptoStreamMode.Write);
    
    deStream.Write(fout.ToArray(),0,(int)(fout.Length));
    
    Console.WriteLine(Encoding.ASCII.GetString((fin.ToArray())));
    
    string outputString = Convert.ToBase64String(fout.ToArray());
    
    Console.WriteLine(outputString);
    
    Console.ReadLine();
}

  编译的错误：
