Mvc Runtime error - The Role Manager feature has not been enabled
提问by kayze
I am trying to implement basic role management manually. When a user logs in if they are admin or not they are added to a role
我正在尝试手动实现基本角色管理。当用户登录时，无论他们是管理员还是非管理员，他们都会被添加到角色中
I am getting this error:Exception Details: System.Configuration.Provider.ProviderException: The Role Manager feature has not been enabled.
我收到此错误：异常详细信息：System.Configuration.Provider.ProviderException：尚未启用角色管理器功能。
This is the method that causes the error:
这是导致错误的方法：
public void addUserToRole(String user, String role)
{
if (!Roles.RoleExists(role))
Roles.CreateRole(role);
Roles.AddUserToRole(user, role);
}
here is my web.config
这是我的 web.config
<profile defaultProvider="DefaultProfileProvider">
<providers>
<add name="DefaultProfileProvider" type="System.Web.Providers.DefaultProfileProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxx" connectionStringName="DefaultConnection" applicationName="/" />
</providers>
</profile>
<membership defaultProvider="DefaultMembershipProvider">

By default the role manger is disabled, so you have to enable it explicitly:
默认情况下，角色管理器是禁用的，因此您必须明确启用它：
<roleManager enabled="true" defaultProvider="DefaultRoleProvider">
回答by Spock
With your DefaultRoleProvider try this
使用您的 DefaultRoleProvider 试试这个
<roleManager defaultProvider="DefaultRoleProvider" enabled ="true">

I tried this in MVC 5 and it worked:
我在 MVC 5 中尝试过这个并且它有效：
<system.web>
<authentication mode="None" />
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
<roleManager enabled="true" />
</system.web>
After adding the "roleManager" line shown above to the web.config, I could add a new role and add a user to the role without any exception:
将上面显示的“roleManager”行添加到 web.config 后，我可以添加一个新角色并将用户添加到角色中，没有任何异常：
if (!Roles.RoleExists(_role))
Roles.CreateRole(_role);
if (!Roles.IsUserInRole(_username, _role))
Roles.AddUserToRole(_username, _role);
