一：构建U8登陆对象

 一：引用U813.0的登陆dll

 二：编写获取登陆对象方法

 /// <summary>
        /// 构建登录对象
        /// </summary>
        /// <param name="sSubId">U8子模块</param>
        /// <param name="sAccId">账套ID</param>
        /// <param name="sYear">年份</param>
        /// <param name="sUserId">用户账号</param>
        /// <param name="sPassword">用户密码</param>
        /// <param name="sDate">登陆日期</param>
        /// <param name="sServer">登陆服务器地址</param>
        /// <param name="sSerial">默认空</param>
        /// <returns></returns>
        public static U8Login.clsLogin GetU8Login(String sSubId, String sAccId, String sYear, String sUserId, String sPassword, String sDate, String sServer, String sSerial)
        {
            U8Login.clsLogin U8Login = new U8Login.clsLogin();
            bool bSucess = false;
            try
            {
                bSucess = U8Login.Login(ref sSubId, ref sAccId, ref sYear, ref sUserId, ref sPassword, ref sDate, ref sServer, ref sSerial);
                if (bSucess == false)
                {
                    String errMsg = "登陆失败,原因:" + U8Login.ShareString;
                    throw new Exception(errMsg);
                }
                else
                {
                    return U8Login;
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

三：登陆参数

   string sSubId = "ST";
            string sAccId = "001";
            string sYear = "2020";
            string sUserId = "wf";
            string sPassword = "";
            string sServer = "127.0.0.1";
            string sSerial = "";
            string Msg = "";
            string sDate = "2020-04-09";  
            U8Login.clsLogin u8login = GetU8Login(sSubId, sAccId, sYear, sUserId, sPassword, sDate, sServer, sSerial);
            string userToken = u8login.userToken;
            string cUserName = u8login.cUserName;
