Answer 1

参考过了，谢谢啦！已经搞定了，是加密模式搞错了。。贴出修改后的源码：    public static string DES3Decrypt(string data, string key)
    {
        TripleDESCryptoServiceProvider DES = new TripleDESCryptoServiceProvider();        DES.Key = ASCIIEncoding.ASCII.GetBytes(key);
        DES.Mode = CipherMode.ECB;
        DES.Padding = System.Security.Cryptography.PaddingMode.PKCS7;        ICryptoTransform DESDecrypt = DES.CreateDecryptor();        string result = "";
        try
        {
            byte[] Buffer = Convert.FromBase64String(data);
            result = ASCIIEncoding.ASCII.GetString(DESDecrypt.TransformFinalBlock(Buffer, 0, Buffer.Length));
        }
        catch (Exception e)
        {        }
        return result;
    }

应该是ecb，平台是ecb模式加密的。
