修改操作也很简单，相应的dall代码我就不再贴出来了，下面贴一下bll层的吧

[C#] 纯文本查看 复制代码

 public class LoginUserBLL
    {
      LoginUserDAL dal = new LoginUserDAL();
 /// <summary>
      /// 更新对象
      /// </summary>
      /// <param name="info">LoginUserInfo对象</param>
      /// <returns></returns>
      public int UpdateLoginUserInfo(LoginUserInfo info)
      {
          return dal.UpdateLoginUserInfo(info);
      }
    }
}

[C#] 纯文本查看 复制代码

  public class UserBLL
    {
        UserDAL dal=new UserDAL();
 /// <summary>
        /// 修改一条记录
        /// </summary>
        /// <param name="user"></param>
        /// <returns></returns>
        public int UpdateUserInfo(UserInfo user)
        {
            return dal.UpdateUserInfo(user);
        }
}

下面是web前段代码：

protected void Page_Load(object sender, EventArgs e)[/align]        {
            if (!IsPostBack)
            {
                BindSelect();//这个会在下一篇专门介绍如何使用静态集合
                DoUpdate();
            }
        }
public void DoUpdate()
        {
            //修改操作初始化
            if (Request["id"] != null)
            {
                string id = Request["id"];
                int userId = 0;
                if (!int.TryParse(id, out userId))
                {
                    return;
                }
                //通过userId获取当前LoginUserInfo对象和UserInfo对象
                LoginUserInfo loginuser = loginbll.FindById(userId);
                UserInfo user = userbll.FindById(userId);
                if (loginuser == null || user == null)
                {
                    return;
                }
                //以下是页面初始化操作
               txtUserName.Value=user.Name;
               ddlGender.Value=user.Sex.ToString();
               txtPhone.Value=user.Phone;

            }
        }
protected void btnOk_Click(object sender, EventArgs e)
        {

            if (Page.IsValid)
            {

                {
                    return;

            }
        }
  /// <summary>

        public UserInfo GetUser()
        {
            string name = txtUserName.Value;
            string phone = txtPhone.Value.Trim(); ;

            string loginIP = Request.UserHostAddress;
            LoginUserInfo loginuser = new LoginUserInfo
            {
                ID = userId,
                UserName = loginUser,
                UserPwd = pwd,
                LoginIp = loginIP,
                UserStatus = (UserStatus)int.Parse(userStatus),
                LoginType = (LoginType)int.Parse(loginType)
            };
            return loginuser;
        }

好了这就已经搞定了，效果图很简单我就不再贴了，无非就是修改成功跳转到列表这些常规的方式了。
