您好，并提前致谢
我迷路了，我不知道我的代码有什么问题，而且我一直在努力遵循在 http://www.brianlegg.com/post/2011/05/09/Implementing-your-own-RoleProvider-and-MembershipProvider-in-MVC-3.aspx并进行更改以匹配我自己的数据库。
首先，这是我的数据库脚本（ssms）的相关部分
CREATE TABLE BFS.dbo.BFSSUSER(
ID int IDENTITY(1,1),
RoleID int,
Name nvarchar(50)NOT NULL,
SiteName nvarchar(50)NOT NULL,
UserPassword nvarchar(20),
CONSTRAINT BFSSUSER_pk PRIMARY KEY (ID))
GO
USE BFS
GO
CREATE TABLE BFS.dbo.ROLE(
ID int IDENTITY(1,1),
Name nvarchar(50)NOT NULL
CONSTRAINT ROLE_pk PRIMARY KEY (ID),
CONSTRAINT ROLE_fk FOREIGN KEY (ID) REFERENCES BFSUSER(ID))
GO
好的，我正在尝试制作我的提供者并使用存储库类
我会将我的整个代码包含在其中，但是我会从错误的开始位置识别出错误 而且我不知道该怎么做
（我的所有if roleExists声明都是红色的并且让我疯狂（34个错误!!!），我已经尝试了几种组合让它们消失并且（基本上我很糟糕）任何所有的帮助都会很大赞赏（记得我的品牌打击asp.net新手，不知道什么是什么或意味着什么!!）

任何和所有帮助将不胜感激
特别向我解释或显示它何时需要是表名，变量名等。我很困惑，因为我的表名是角色，我正在做的是角色
答案 0 :(得分：1)
通过几个步骤创建自定义成员资格提供程序：
throw new NotImplementedException();正文public override MembershipUser GetUser(object providerUserKey, bool userIsOnline) public override MembershipUser GetUser(string username, bool userIsOnline) public override bool ValidateUser(string username, string password) 配置web.config以使用您的自定义成员资格提供程序：
<membership defaultProvider="CurrentProvider" userIsOnlineTimeWindow="10">
<providers>
<add name="CurrentProvider" Type="YOUR.WEBAPP.PROVIDERS.CustomMembershipProvider" />
</providers>
</membership>
对于MVC4必须添加或设置以下AppSettings：
<add key="enableSimpleMembership" value="false" />
<add key="autoFormsAuthentication" value="false" />
对于自定义角色提供程序，它几乎与程序相同
RoleProvider（MVC3和4）进行继承public override bool IsUserInRole(string username, string roleName) public override string[] GetRolesForUser(string username) <roleManager defaultProvider="CurrentProvider" enabled="true">
<providers>
<add name="CurrentProvider" type="YOUR.WEBAPP.PROVIDERS.CustomRoleProvider" />
</providers>
</roleManager>
如果你使用隶属函数并抛出NotImplementedException，你就知道你必须覆盖抛出异常的方法。
