asp.net基于三层架构、MVC和SQLServer2012实现用户注册

Question

一、三层架构
1、业务逻辑层（BLL）
（1）RegisterManage.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Models;
namespace BLL
{
public class RegisterManager
{
public bool Register(Customer objCustomer)
{
//和数据库交互，判断当前用户名、Email是否已经被使用，
//如果没有被使用则直接注册
return false;
}
}
}
2、数据访问层（DAL）
（1）SQLHelper.cs
（2）RegisterService.cs
3、模型层（Models）
（1）User.cs
二、MVC
（1）控制器
（2）强类型视图
三、SQLServer2012
User.sql

Answer 1

public class Employee
{
public string Id { get; private set; }
public string Name { get; private set; }
public string Gender { get; private set; }
public DateTime BirthDate { get; private set; }
public string Department { get; private set; }

public Employee(string id,string name,string gender,DateTime birthDate,string department)
{
    Id          = id;
    Name        = name;
    Gender      = gender;
    BirthDate   = birthDate;
    Department  = department;
}

}

public class EmployeeRespository
{
private static IList employees;

static EmployeeRespository()
{
    employees = new List<Employee>()
    {
        new Employee("001","张三","男",new DateTime(1981,8,24),"销售部"),
        new Employee("002","李四","男",new DateTime(1981,8,24),"人事部"),
        new Employee("003","王五","女",new DateTime(1981,8,24),"人事部")
    };
}

public IEnumerable<Employee> GetEmployees(string department = "")
{
    if (string.IsNullOrEmpty(department))
    {
        return employees;
    }
    return employees.Where(e => e.Department == department).ToArray();
}

}
