步步为营 .NET三层架构解析七、UI的设计(登陆页面、注册页页和添加部门页面)...

生活随笔收集整理的這篇文章主要介紹了步步为营 .NET三层架构解析七、UI的设计(登陆页面、注册页页和添加部门页面)... 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

在我們設計好了三層架構的SQLHelper、Model、DAL和BLL后，我們要開始來調用它設計好的功能了。

首先我們來設計Login.aspx,先看界面的設計：

再來看Login.aspx.cs的設計：

記得加上這個：

using BLL; using Model;

而后才是：

protected void Page_Load(object sender, EventArgs e){}protected void btnLogin_Click1(object sender, EventArgs e){custom Custom = new custom();customSystem CustomSystem = new customSystem();Custom = CustomSystem.GetSinglename(txtUserName.Text.Trim().ToString());if (Custom.ename == txtUserName.Text.Trim().ToString()){// 密碼是經過MD5加密后保存到數據庫的 if (Custom.password == FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassWord.Text.Trim().ToString(), "MD5")){department Department = new department();departmentSystem DepartmentSystem = new departmentSystem();Department = DepartmentSystem.Getsingledepartment(Custom.departID);SetSession(Department,Custom.departID.ToString());}else{Response.Write("<script>alert('密碼錯誤');location.href='Login.aspx';</script>");}}else{Response.Write("<script>alert('帳戶名不存在');location.href='Login.aspx';</script>");}}private void SetSession(department Department,string DepartID){if (Department == null || string.IsNullOrEmpty(DepartID)){Response.Write("<script>alert('網站運行錯誤或你沒設置部門信息,請聯系管理員.');location.href='Login.aspx';</script>");return;}Session["Ename"] = txtUserName.Text.Trim().ToString();Session["Departid"] = DepartID;Session["Operater"] = "";if (Department.departname == "控制中心"){Response.Write("<script>alert('登錄成功');location.href='Default.aspx';</script>");}else{Response.Write("<script>alert('登錄成功');location.href='Default2.aspx';</script>");}}

接下來我們要在App_Code文件下新建PageBase.cs

public bool IsAdmin(){if (Session["Departid"] != null){department Department = new department();departmentSystem DepartmentSystem = new departmentSystem();Department = DepartmentSystem.Getsingledepartment(int.Parse(Session["Departid"].ToString()));if (Department.departname != "控制中心"){Response.Redirect("/Web/Login.aspx");Response.End();return false;}}else{Response.Redirect("/Web/Login.aspx");Response.End();return false;}return true;}

加入下面之個方法：

再來看下ADDdepart.aspx的設計：

ADDdepart.aspx.cs的設計：

//繼承PageBase類 public partial class ADDdepart : PageBase {protected void Page_Load(object sender, EventArgs e){if (!Page.IsPostBack){IsAdmin();}}protected void btnAdd_Click(object sender, EventArgs e){department Department = new department();department Departmenter = new department();departmentSystem DepartmentSystem = new departmentSystem();Department.departname = txtDepartmentName.Text.Trim();Department.description = txtDescription.Text.Trim();Departmenter = DepartmentSystem.Getdepartmenter(txtDepartmentName.Text.Trim());if (Departmenter.id <= 0){if (DepartmentSystem.Adddepartment(Department) >= 1){ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>alert('恭喜您，部門添加成功！');</script>");}}else{ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>alert('您填的部門己存在,請更改!');</script>");}} }

再來看下注冊頁面Register.aspx的設計：

下面是Register.aspx.cs的設計:

protected void Page_Load(object sender, EventArgs e){if (!IsPostBack){ BinData();}}public void BinData(){List<department> Departmentlist = new List<department>();departmentSystem DepartmentSystem = new departmentSystem();Departmentlist = DepartmentSystem.GetDepartment();ddlDepartment.DataSource = Departmentlist;ddlDepartment.DataTextField = "departname";ddlDepartment.DataValueField = "id";ddlDepartment.DataBind();}protected void btnLogin_Click(object sender, EventArgs e){custom Custom = new custom();customSystem CustomSystem = new customSystem();custom Customn = new custom();Customn = CustomSystem.GetSinglename(txtUserName.Text.Trim());if (Customn.id <= 0){Custom.ename = txtUserName.Text.Trim();Custom.cname = txtName.Text.Trim();Custom.age = Convert.ToInt32(txtAge.Text.Trim());Custom.password = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassWord.Text.Trim(), "MD5");Custom.departID = int.Parse(ddlDepartment.SelectedValue);if (CustomSystem.customADD(Custom) >= 1){ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>alert('恭喜您，帳號添加成功！');</script>");}}else{ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>alert('你輸入的帳戶名己存在,請更改！');</script>");}}

以上只是UI簡單的調用BLL的功能,下次再講解下GridView調用BLL和GridView的分頁,可能我設計的只是較簡單,歡迎大家提出你們寶貴的意見.來共同提高.歡迎拍磚.
