用三層架構(gòu)實(shí)現(xiàn)登錄，并模擬后臺(tái)審核功能，未審核成功不予登錄（ASP.NET）

先建如下項(xiàng)目：

先寫模型層

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; }
        }
    }
}

用三層架構(gòu)實(shí)現(xiàn)登錄，并模擬后臺(tái)審核功能，未審核成功不予登錄（ASP.NET）

然后寫數(shù)據(jù)鏈路層：

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
    {
        ///

/// 驗(yàn)證用戶登陸
///

        ///
        ///
        ///
        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;
        }
    }
}

用三層架構(gòu)實(shí)現(xiàn)登錄，并模擬后臺(tái)審核功能，未審核成功不予登錄（ASP.NET）

然后寫業(yè)務(wù)層

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; //用戶不存在
            }
            else if (obj.ToString().Trim() == student.StuPwd)
            {
                result = 1;//正確
            }
            else if (obj.ToString().Trim() != student.StuPwd)
            {
                result = 2;//密碼錯(cuò)誤
            }
            else
            {
                result = 3; //系統(tǒng)錯(cuò)誤
            }
            return result;
        }
    }
}
