下面看一个例子:
现在有一个用户信息的表:E-R图如下:
要实现该表的数据库新增、修改、查询功能,需要实现下面两个业务类:
using Csla; using IF.CslaCore; using IF.OrmCore.DataSchema; using System; using System.Collections.Generic; using System.ComponentModel; using System.Linq; using System.Text; using System.Threading.Tasks; namespace IF.SysUser.Business { [Serializable] [TableClass(FriendlyName="用户信息表",TableName="SYS_USER")] public class SysUser : IfBusiness<SysUser> { private static readonly PropertyInfo<string> SUR_IDProperty = RegisterProperty<string>(c => c.SUR_ID); [DisplayName("SUR_ID")] [FieldDescription(IsPrimaryKey=true,ColumnName="SUR_ID",FriendlyName="SUR_ID",NeedUpdate=true)] public string SUR_ID { get; set; } private static readonly PropertyInfo<string> UserNameProperty = RegisterProperty<string>(c => c.UserName); [DisplayName("登录名")] [FieldDescription(ColumnName="SUR_USERNAME",FriendlyName="登录名",NeedUpdate=true)] public string UserName { get; set; } private static readonly PropertyInfo<string> NameProperty = RegisterProperty<string>(c => c.Name); [DisplayName("姓名")] [FieldDescription(ColumnName="SUR_NAME",FriendlyName="姓名",NeedUpdate=true)] public string Name { get; set; } private static readonly PropertyInfo<string> PasswordProperty = RegisterProperty<string>(c => c.Password); [DisplayName("密码")] [FieldDescription(ColumnName="SUR_PASSWORD",FriendlyName="密码",NeedUpdate=true)] public string Password { get; set; } private static readonly PropertyInfo<string> LoginMacProperty = RegisterProperty<string>(c => c.LoginMac); [DisplayName("登录Mac地址")] [FieldDescription(ColumnName="SUR_LOGIN_MAC",FriendlyName="登录Mac地址",NeedUpdate=true)] public string LoginMac { get; set; } private static readonly PropertyInfo<string> LoginIPProperty = RegisterProperty<string>(c => c.LoginIP); [DisplayName("登录IP")] [FieldDescription(ColumnName="SUR_LOGIN_IP",FriendlyName="登录IP",NeedUpdate=true)] public string LoginIP { get; set; } private static readonly PropertyInfo<DateTime > LoginTimeProperty = RegisterProperty<DateTime >(c => c.LoginTime); [DisplayName("登录时间")] [FieldDescription(ColumnName="SUR_LOGIN_TIME",FriendlyName="登录时间",NeedUpdate=true)] public DateTime LoginTime { get; set; } private static readonly PropertyInfo<DateTime > LogoutTimeProperty = RegisterProperty<DateTime >(c => c.LogoutTime); [DisplayName("登出时间")] [FieldDescription(ColumnName="SUR_LOGOUT_TIME",FriendlyName="登出时间",NeedUpdate=true)] public DateTime LogoutTime { get; set; } private static readonly PropertyInfo<DateTime > LoginFailTimeProperty = RegisterProperty<DateTime >(c => c.LoginFailTime); [DisplayName("登录失败时间")] [FieldDescription(ColumnName="SUR_LOGIN_FAIL_TIME",FriendlyName="登录失败时间",NeedUpdate=true)] public DateTime LoginFailTime { get; set; } private static readonly PropertyInfo<Int32 > LoginFailCountProperty = RegisterProperty<Int32 >(c => c.LoginFailCount); [DisplayName("登录失败次数")] [FieldDescription(ColumnName="SUR_LOGIN_FAIL_COUNT",FriendlyName="登录失败次数",NeedUpdate=true)] public Int32 LoginFailCount { get; set; } private static readonly PropertyInfo<bool > LockFGProperty = RegisterProperty<bool >(c => c.LockFG); [DisplayName("是否锁定")] [FieldDescription(ColumnName="SUR_LOCK_FG",FriendlyName="是否锁定",NeedUpdate=true)] public bool LockFG { get; set; } private static readonly PropertyInfo<bool > DisableFGProperty = RegisterProperty<bool >(c => c.DisableFG); [DisplayName("是否有效")] [FieldDescription(ColumnName="SUR_DISABLE_FG",FriendlyName="是否有效",NeedUpdate=true)] public bool DisableFG { get; set; } #region 通用字段 private static readonly PropertyInfo<DateTime > CreateTimeProperty = RegisterProperty<DateTime >(c => c.CreateTime); [DisplayName("创建时间")] [FieldDescription(ColumnName="CreateTime",FriendlyName="创建时间",NeedUpdate=true)] public override DateTime CreateTime { get; set; } private static readonly PropertyInfo<DateTime > LastUpdateTimeProperty = RegisterProperty<DateTime >(c => c.LastUpdateTime); [DisplayName("最后修改时间")] [FieldDescription(ColumnName="LastUpdateTime",FriendlyName="最后修改时间",NeedUpdate=true)] public override DateTime LastUpdateTime { get; set; } public override void SetPrimaryKey(string key) { SUR_ID = key; } #endregion } [Serializable] public class SysUserList : IfBusinessList<SysUserList, SysUser> { } }
现在就可以工作了: 全表检索数据方法: SysUserList selData = SysUserList.Fetch();
向数据库新增一条数据: SysUser.Business.SysUser user = new SysUser.Business.SysUser(); user.UserName= "inaction"; user.Name = "流砂"; user.Password= "superman"; selData.Add(user); selData.Save();
向数据库修改数据: var user = SysUserList.Fetch(c => c.UserName == "inaction"); user.Password = "123456"; SysUserList list = new SysUserList { user }; list.Save();
以上代码就实现了对密码的修改。 特别说明:目前IF 只能通过SysUserList对象的Save方法保存数据。以后会实现通过业务类自身Save方法保存数据。 原文链接:http://www.cnblogs.com/nactioncsla/p/3439820.html
