MVC 5 Access Claims Identity User Data

Question

I am developing an MVC 5 web application using Entity Framework 5 Database First approach  I am using OWIN for the authentication of Users  Below shows my Login method within my Account Controller   public ActionResult Login LoginViewModel model  string returnUrl        if  ModelState IsValid                var user    AccountService VerifyPassword model UserName  model Password  false           if  user    null                        var identity   new ClaimsIdentity new     new Claim ClaimTypes Name  model UserName      DefaultAuthenticationTypes ApplicationCookie  ClaimTypes Name  ClaimTypes Role                identity AddClaim new Claim ClaimTypes Role   guest                 identity AddClaim new Claim ClaimTypes GivenName   A Person                 identity AddClaim new Claim ClaimTypes Sid  user userID      OK to store userID here               AuthenticationManager SignIn new AuthenticationProperties                               IsPersistent   model RememberMe                identity                return RedirectToAction  Index    MyDashboard                      else                       ModelState AddModelError      Invalid username or password                            If we got this far  something failed  redisplay form     return View model       As you can see I m creating a ClaimsIdentity and adding several claims to it  then passing it to OWIN using the AuthenticationManager to perform the sign in   The problem I am having is that I m not sure how to access the claims in the rest of my application  either in Controllers or in Razor Views   I had tried the approach listed in this tutorial  http   brockallen com 2013 10 24 a-primer-on-owin-cookie-authentication-middleware-for-the-asp-net-developer   For example  I tried this in my Controller code in an attempt to get access to the values passed into the Claims  however  the user Claims is equal to null  var ctx   HttpContext GetOwinContext    ClaimsPrincipal user   ctx Authentication User  IEnumerable lt Claim gt  claims   user Claims    Perhaps I am missing something here    UPDATE  Based on Darin s answer  I added his code but still I fail to see access to the Claims  Please see screenshot below showing what I see when hovered over identity Claims

I make my own extended class to see what I need, so when I need into my controller or my View, I only add the using to my namespace something like this:

public static class UserExtended
{
    public static string GetFullName(this IPrincipal user)
    {
        var claim = ((ClaimsIdentity)user.Identity).FindFirst(ClaimTypes.Name);
        return claim == null ? null : claim.Value;
    }
    public static string GetAddress(this IPrincipal user)
    {
        var claim = ((ClaimsIdentity)user.Identity).FindFirst(ClaimTypes.StreetAddress);
        return claim == null ? null : claim.Value;
    }
    public ....
    {
      .....
    }
}

In my controller:

using XXX.CodeHelpers.Extended;

var claimAddress = User.GetAddress();

In my razor:

@using DinexWebSeller.CodeHelpers.Extended;

@User.GetFullName()

I used it like that in my base controller  Just sharing for ready to use         public string GetCurrentUserEmail             var identity    ClaimsIdentity User Identity          IEnumerable lt Claim gt  claims   identity Claims          var email   claims Where c   gt  c Type    ClaimTypes Email  ToList            return email 0  Value ToString               public string GetCurrentUserRole                 var identity    ClaimsIdentity User Identity          IEnumerable lt Claim gt  claims   identity Claims          var role   claims Where c   gt  c Type    ClaimTypes Role  ToList            return role 0  Value ToString

You can also do this     Get the current claims principal var identity    ClaimsPrincipal Thread CurrentPrincipal  var claims   identity Claims    Update  To provide further explanation as per comments   If you are creating users within your system as follows   UserManager lt applicationuser gt  userManager   new UserManager lt applicationuser gt  new UserStore lt applicationuser gt  new SecurityContext      ClaimsIdentity identity   userManager CreateIdentity user  DefaultAuthenticationTypes ApplicationCookie     You should automatically have some Claims populated relating to you Identity   To add customized claims after a user authenticates you can do this as follows   var user   userManager Find userName  password   identity AddClaim new Claim ClaimTypes Email  user Email      The claims can be read back out as Darin has answered above or as I have   The claims are persisted when you call below passing the identity in   AuthenticationManager SignIn new AuthenticationProperties     IsPersistent   persistCookie    identity

Remember that in order to query the IEnumerable you need to reference system linq  It will give you the extension object needed to do   CaimsList FirstOrDefault x  gt x Type    variableName   toString

var claim   User Claims FirstOrDefault c   gt  c Type     claim type here

Request GetOwinContext   Authentication User Claims   However it is better to add the claims inside the  GenerateUserIdentityAsync  method  especially if regenerateIdentity in the Startup Auth cs is enabled

This is an alternative if you don t want to use claims all the time   Take a look at this tutorial by Ben Foster   public class AppUser   ClaimsPrincipal       public AppUser ClaimsPrincipal principal            base principal                   public string Name               get                       return this FindFirst ClaimTypes Name  Value                        Then you can add a base controller   public abstract class AppController   Controller              public AppUser CurrentUser               get                       return new AppUser this User as ClaimsPrincipal                       In you controller  you would do   public class HomeController   AppController       public ActionResult Index                 ViewBag Name   CurrentUser Name          return View

To further touch on Darin s answer  you can get to your specific claims by using the FindFirst method   var identity    ClaimsIdentity User Identity  var role   identity FindFirst ClaimTypes Role  Value
