如何检查用户是在asp.net的身份很多角色 [英] How to check user is in many roles in asp.net identity

问题描述

您好我需要检查，如果用户是在角色之一，我很困惑与不同版本的code的，我发现。让我告诉你我有什么，此刻第一个

Hi I need to check if a user is in one of the roles and i am confused with different versions of code that i found. Let me show you what i have at the moment first

_manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());

var currentUser = _manager.FindById(User.Identity.GetUserId());      

if (!_manager.IsInRole(currentUser.Id, "admin"))
{

}

和ApplicationUser

And ApplicationUser

public class ApplicationUser : IdentityUser
{        
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{

}

所以我要检查，如果用户是在角色之一。例如管理，controbutor，superuser等等。

So i want to check if the user is in one of the roles. e.g. admin, controbutor, superuser, etc.

我发现<一个href=\"http://stackoverflow.com/questions/14477757/how-can-i-check-if-a-user-is-in-any-one-of-a-few-different-roles-with-mvc4-simpl\">this例如这似乎是一个好一个，但我必须把web.config中的以下更改，使其工作。我也没必要做我的code作为我现在有。

I found this example which seems a good one but i have to put the following changes in web.config to make it work. I didn't need to do that with my code as i have currently.

roleManager enabled="true"

我尝试研究更多关于 UserManager.IsInRole 但我coundn't找到许多关于它的。更位阅读我了解我发现文章是关于简单的会员。

I try to research more on UserManager.IsInRole but I coundn't find many about it. A bit more reading i understand the post i found is about Simple Membership.

由于我使用的身份，我不应该使用code，我发现（指链路和接受的答案），作为将要混合身份和简单的会员资格？特别我指的是这行 Roles.GetRolesForUser 。是否有身份类似的方法？我想我感到困惑的不同成员的框架和不知道什么是正确的用途。我希望有人能解释我明白。

As I am using Identity, i should not use the code that i found (refers to the link and accepted answer) as that will be mixing of Identity and Simple Membership? Specially i refer to this line Roles.GetRolesForUser. Is there similar method for Identity? I think I am confused about different membership frameworks and don't know what is the proper uses. I hope someone can explain me to understand.

（我还是想对我提出的问题的称号，但我真的需要理解，以及表示溶液）

(I still want the solution for the question i asked in the title but i really need to understand as well =)

推荐答案

好吧，我发现了一个办法做到这一点。我不知道用户对象通过返回的UserManager有角色财产角色的集合，用户拥有。

Well I found a way to do it. I didn't know User object that returns by UserManager has Roles property with the collection of roles that the user has.

using Microsoft.AspNet.Identity;
var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());

var roles = new List<string> { "admin", "contributor" };
var currentUser = manager.FindById(User.Identity.GetUserId());  

if (currentUser.Roles.Any(u => roles.Contains(u.Role.Name)))
{

}
