获取ASP.NET MVC5身份系统中的所有角色名称

Question

MVC5 uses a new Identity System. How can I get all role names?

I try do access it via IdentityStore but without success.

Answer 1

这更直观一些

var roles = dbContext.Roles.OrderBy(x => x.Name);

Answer 2

I've found that you can use the DbContext via the IdentityStore instance and use the well-known method .Set<T>() .

This works for me:

var identityStore = new IdentityStore();
foreach (var role in identityStore.DbContext.Set<Role>())
{
    Debug.WriteLine(role.Name);
}

Answer 3

There's currently no way to do enumeration style methods via the identity interfaces, that will be coming in a future update targeting administration scenarios(post 1.0 RTM), so there's no way to enumerate all users or roles via the Identity APIs. That said, you can always drop down to EF or whatever the store implementation is to directly enumerate the roles/users.
