    public class Test : IRequestModel
    {
        public string aaa1 { get; set; }
        public string aaa2 { get; set; }
        public string aaa3 { get; set; }
        public string aaa4 { get; set; }
        public string aaa5 { get; set; }
    }

    public interface IRequestModel
    {
    }

    [XmlRoot("CPMB2B")]
    public class RequestObj<T> where T : IRequestModel
    {
        public RequestMessageData<T> MessageData { get; set; }
    }

    public class RequestMessageData<T> where T : IRequestModel
    {
        public ModelBase Base { get; set; }
        public RequestHeader ReqHeader { get; set; }
        public T DataBody { get; set; }
    }

    public class RequestHeader
    {
        public RequestHeader() { }
        public RequestHeader(string merchantNo, string transCode, string transCodeId)
        {
            ClientTime = DateTime.Now.ToString("yyyyMMddHHmmss");
            MerchantNo = merchantNo;
            TransCode = transCode;
            TransCodeId = transCodeId;
        }
        public string ClientTime { get; set; }
        public string MerchantNo { get; set; }
        public string TransCodeId { get; set; }
        public string TransCode { get; set; }
    }

    public class ModelBase
    {
        /// <summary>
        /// 版本号，交易时要判断版本匹配
        /// </summary>
        public string Version { get; set; } = "2.3";

        /// <summary>
        /// 签名标志:0=未包含签名；1=包含签名
        /// </summary>
        public string SignFlag { get; set; } = "1";
