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)
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：
<table>
<tr>
<td style= " 100px; text-align: right" >
帐户名:</td>
<td style= " 100px" >
<asp:TextBox ID= "txtUserName" runat= "server" ></asp:TextBox></td>
</tr>
<tr>
<td style= " 100px; text-align: right" >
密码:</td>
<td style= " 100px" >
<asp:TextBox ID= "txtPassWord" runat= "server" TextMode= "Password" ></asp:TextBox></td>
</tr>
<tr>
<td style= " 100px" >
</td>
<td style= " 100px" >
<asp:Button ID= "btnLogin" runat= "server" OnClick= "btnLogin_Click1" Text= "登陆" /></td>
</tr>
</table>
再来看Login.aspx.cs的设计：
记得加上这个：
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())
{
// 密码是经过MD5加密后保存到数据库的
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('密码错误');location.href='Login.aspx';</script>" );
}
}
else
{
Response.Write( "<script>alert('帐户名不存在');location.href='Login.aspx';</script>" );
}
}
private void SetSession(department Department, string DepartID)
{
if (Department == null || string .IsNullOrEmpty(DepartID))
{
Response.Write( "<script>alert('网站运行错误或你没设置部门信息,请联系管理员.');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('登录成功');location.href='Default.aspx';</script>" );
}
else
{
Response.Write( "<script>alert('登录成功');location.href='Default2.aspx';</script>" );
}
}
接下来我们要在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 ;
}
加入下面之个方法：
再来看下ADDdepart.aspx的设计：
<table>
<tr>
<td style= " 100px" >
部门名称：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtDepartmentName" runat= "server" ></asp:TextBox></td>
</tr>
<tr>
<td style= " 100px" >
描述：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtDescription" runat= "server" ></asp:TextBox></td>
</tr>
<tr>
<td style= " 100px" >
</td>
<td style= " 100px" >
<asp:Button ID= "btnAdd" runat= "server" OnClick= "btnAdd_Click" Text= "增加" /></td>
</tr>
</table>
ADDdepart.aspx.cs的设计：
//继承PageBase类
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，部门添加成功！');</script>" );
}
}
else
{
ClientScript.RegisterClientScriptBlock( this .GetType(), "" , "<script>alert('您填的部门己存在,请更改!');</script>" );
}
}
}
再来看下注册页面Register.aspx的设计：
<table>
<tr>
<td style= " 100px; text-align: right" >
帐户名：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtUserName" runat= "server" ></asp:TextBox></td>
<td style= " 100px" >
</td>
</tr>
<tr>
<td style= " 100px; text-align: right;" >
姓名：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtName" runat= "server" ></asp:TextBox></td>
<td style= " 100px" >
</td>
</tr>
<tr>
<td style= " 100px; text-align: right;" >
年龄：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtAge" runat= "server" ></asp:TextBox></td>
<td style= " 100px" >
</td>
</tr>
<tr>
<td style= " 100px; text-align: right;" >
密码：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtPassWord" runat= "server" TextMode= "Password" ></asp:TextBox></td>
<td style= " 100px" >
<asp:CompareValidator ID= "CompareValidator1" runat= "server" ControlToCompare= "TextBox4"
ControlToValidate= "TextBox5" ErrorMessage= "密码不一样" ></asp:CompareValidator></td>
</tr>
<tr>
<td style= " 100px; text-align: right;" >
重复密码：</td>
<td style= " 100px" >
<asp:TextBox ID= "txtConfirmPassWord" runat= "server" TextMode= "Password" ></asp:TextBox></td>
<td style= " 100px" >
</td>
</tr>
<tr>
<td style= " 100px; text-align: right;" >
部门：</td>
<td style= " 100px" >
<asp:DropDownList ID= "ddlDepartment" runat= "server" >
</asp:DropDownList></td>
<td style= " 100px" >
</td>
</tr>
<tr>
<td style= " 100px" >
</td>
<td style= " 100px" >
<asp:Button ID= "btnLogin" runat= "server" OnClick= "btnLogin_Click" Text= "注册" /></td>
<td style= " 100px" >
</td>
</tr>
</table>
下面是Register.aspx.cs的设计:
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，帐号添加成功！');</script>" );
}
}
else
{
ClientScript.RegisterClientScriptBlock( this .GetType(), "" , "<script>alert('你输入的帐户名己存在,请更改！');</script>" );
}
}
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.
