在我们设计好了三层架构的SQLHelper、Model、DAL和BLL后，我们要开始来调用它设计好的功能了。首先我们来设计Login.aspx,先看界面的设计：view sourceprint?

再来看Login.aspx.cs的设计：记得加上这个：view sourceprint?using BLL;  using Model; 而后才是：view sourceprint?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())      {           // 密码是经过MD5加密后保存到数据库的
view sourceprint?        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("");          }      }      else     {          Response.Write("");      }    }  private void SetSession(department Department,string DepartID)  {      if (Department == null || string.IsNullOrEmpty(DepartID))      {          Response.Write("");          return;      }      Session["Ename"] = txtUserName.Text.Trim().ToString();      Session["Departid"] = DepartID;      Session["Operater"] = "";      if (Department.departname == "控制中心")      {          Response.Write("");      }      else     {          Response.Write("");      }  } 接下来我们要在App_Code文件下新建PageBase.cs
view sourceprint?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;  }
加入下面之个方法：再来看下ADDdepart.aspx的设计：view sourceprint?

ADDdepart.aspx.cs的设计：view sourceprint?//继承PageBase类
view sourceprint?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(), "", "");              }          }          else         {              ClientScript.RegisterClientScriptBlock(this.GetType(), "", "");          }    }  } 再来看下注册页面Register.aspx的设计：view sourceprint?

下面是Register.aspx.cs的设计:view sourceprint?protected void Page_Load(object sender, EventArgs e)   {               if (!IsPostBack)       {            BinData();       }   }   public void BinData()   {       List Departmentlist = new List();       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(), "", "");           }       }       else      {           ClientScript.RegisterClientScriptBlock(this.GetType(), "", "");       }   } 以上只是UI简单的调用BLL的功能,下次再讲解下GridView调用BLL和GridView的分页,可能我设计的只是较简单,欢迎大家提出你们宝贵的意见.来共同提高.欢迎拍砖. 摘自红色黑客联盟(www.7747.net) 原文：http://www.7747.net/kf/201103/86550.html
