用三层架构实现登录，并模拟后台审核功能，未审核成功不予登录（ASP.NET）

先建如下项目：





先写模型层

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Model

{

public class Student

{

private string stuId;

public string StuId

{

get { return stuId; }

set { stuId = value; }

}

private string stuPwd;

public string StuPwd

{

get { return stuPwd; }

set { stuPwd = value; }

}

private string stuName;

public string StuName

{

get { return stuName; }

set { stuName = value; }

}

private string stuAge;

public string StuAge

{

get { return stuAge; }

set { stuAge = value; }

}

private string stuSex;

public string StuSex

{

get { return stuSex; }

set { stuSex = value; }

}

private string stuTel;

public string StuTel

{

get { return stuTel; }

set { stuTel = value; }

}

private string stuAddr;

public string StuAddr

{

get { return stuAddr; }

set { stuAddr = value; }

}

private string stuAudit;

public string StuAudit

{

get { return stuAudit; }

set { stuAudit = value; }

}

}

}





然后写数据链路层：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Data.SqlClient;

using System.Data;

using Model;

namespace DAL

{

public class Student_DAL

{

/// <summary>

/// 验证用户登陆

/// </summary>

/// <param name="user"></param>

/// <param name="right"></param>

/// <returns></returns>

public object CheckStuLogin(Student student,string right)

{

string sqlText;

sqlText = "select stuPwd from stuInfo where stuId=@userId";

SqlParameter[] paras = new SqlParameter[1]

{

new SqlParameter("userId",student.StuId)

};

object obj = SqlLink.GetScaler(sqlText, paras);

return obj;

}

}

}













然后写业务层

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using DAL;

using Model;

using System.Data;

namespace BLL

{

public class Student_BLL

{

Student_DAL studal = new Student_DAL();

public int CheckStuLogin(Student student, string right)

{

object obj = studal.CheckStuLogin(student, right);

int result = -1;

if (obj == null)

{

result = 0; //用户不存在

}

else if (obj.ToString().Trim() == student.StuPwd)

{

result = 1;//正确

}

else if (obj.ToString().Trim() != student.StuPwd)

{

result = 2;//密码错误

}

else

{

result = 3; //系统错误

}

return result;

}

}

}





然后写表示层





以上都只是部分的代码及截图。需要详细代码，以及数据库脚本的可以留言，或发邮件。191660130@qq.com

整个项目效果图如下：

通过审核的效果如下





未通过审核的效果如下：









后台审核：
