ASP.NET MVC4.0+EF+LINQ+bui+bootstrap+网站+角色权限管理系统（1）

本系列的的角色权限管理主要采用Dotnet MVC4工程内置的权限管理模块Simplemembership实现，主要有关文件是InitializeSimpleMembershipAttribute.cs和AccountModels.cs

下面是对这两个文件的了解和改造

 WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);表示数据库表不存在的情况下，通过连接到包含用户信息的数据库以及使用指定的成员资格或角色提供程序来初始化成员资格系统。

首先创建一个MVCSystem的空数据库，如下：

然后改造配置文件Web.config数据库链接，注意这里的name="DefaultConnection"与上面的WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);相同

然后运行程序，在空数据库MVCSystem中生成以下数据表（有的可能无法生存webpages_Permission，webpages_PermissionsInRoles表，不过没关系，手动建（字段参考下图）就可以了）

对于运行后无法自动生成数据表的同学，可以点击一下Home page上的注册按钮！

接下来创建和改造Models类：

然后创建一个Common文件夹，主要存储一些公告类：

简述：EF5.0包括Code First和DbContext API。DbContext API为EF提供更多的工作方式：Code First，Database First和Model First。

使用DbContext构造函数

1. Code First约定连接

namespace Magic.Unicorn
{
    public class UnicornsContext : DbContext
    {
        public UnicornsContext()
        // C# will call base class parameterless constructor by default
        {
        }
    }
}

用Magic.Unicorn.UnicornsContext作为数据库名，在本机上生成该数据库的连接字符串（SQL Express）。

2. Code First指定数据库名称的约定连接

public class UnicornsContext : DbContext
{
    public UnicornsContext()
        : base("UnicornsDatabase")
    {
    }
}

MVCStystemContext.cs实体类集合

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;
using MVCSystem.Web.Models;

namespace MVCSystem.Web.Common
{
    public class MVCStystemContext : DbContext
    {
        public MVCStystemContext()
            : base("DefaultConnection")
        {
        }

        public DbSet<M_UserProfile> DB_UserProfiles { get; set; }
        public DbSet<M_Membership> DB_Membership { get; set; }
        public DbSet<M_Roles> DB_Roles { get; set; }
        public DbSet<M_UsersInRoles> DB_UsersInRoles { get; set; }
