简单的物流项目实战，WPF的MVVM设计模式(二)

往Models文件添加一个类，ConnectObject

        /// <summary>
        /// 链接数据库字符串
        /// </summary>
        public string SQLConnect { get; set; }

        /// <summary>
        /// 读取数据
        /// </summary>
        public string SQLRead { get; set; }

        /// <summary>
        /// 新增数据
        /// </summary>
        public string SQLInsert { get; set; }

        /// <summary>
        /// 删除数据
        /// </summary>
        public string SQLDelete { get; set; }

        /// <summary>
        /// 更新数据
        /// </summary>
        public string SQLUpdate { get; set; }

再添加一个User模型类

        /// <summary>
        /// 登录账号
        /// </summary>
        public string UserAccount { get; set; }
        /// <summary>
        /// 登录密码
        /// </summary>
        public string Password { get; set; }

再添加一个Express模型类，

        /// <summary>
        /// 省份
        /// </summary>
        public string Province { get; set; }
        /// <summary>
        /// 城市
        /// </summary>
        public string City { get; set; }
        /// <summary>
        /// 区域
        /// </summary>
        public string Area { get; set; }
        /// <summary>
        /// 街道
        /// </summary>
        public string Street { get; set; }
        /// <summary>
        /// 用户名
        /// </summary>
        public string UserName { get; set; }
        /// <summary>
        /// 手机号码
        /// </summary>
        public string PhoneNumber { get; set; }
        /// <summary>
        /// 创建时间
        /// </summary>
        public string CteateTime { get; set; }

再往Data文件里面添加处理数据的类ConnectToDatabase

        public SQLiteConnection SQLiteConnections;

        public ConnectObject connectObject = new ConnectObject();

        public ConnectToDatabase()
        {
            connectObject.SQLConnect = "Data Source=WMS.db;Version=3;";
            SQLiteConnections = new SQLiteConnection(connectObject.SQLConnect);
            SQLiteConnections.Open();
        }

目前处理的模型类和数据链接类，本文先到这里。敬请期待下一篇详细描述。谢谢观赏！
