MVC User.Identity.Name with first and last names

问题:

I have added First and Last name to the ApplicationUser Class.

 public class ApplicationUser : IdentityUser
    {
        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }

        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

also added information to RegisterViewModel

My application successfully created First and LastName to the table but I am unable to get the first and last names as to display in _LoginPartial "User.Identity.Name"

回答1:

in your partialview _LoginPartial.cshtml

Add the code:

@if (Request.IsAuthenticated)
{
    var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
    var user = manager.FindById(User.Identity.GetUserId());
...
}

ApplicationDbContext = your DBContext -> Default : ApplicationDbContext

With the instance of ApplicationUser (user) you can get First- and LastName-property

Replace User.Identity.Name with user.FirstName + " " + user.LastName like this:

<ul class="nav navbar-nav navbar-right">
    <li>
        @Html.ActionLink("Hello " + user.FirstName + " " + user.LastName + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })
    </li>
    <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li>
</ul>

You'll need to add names as a Claim on user when user is logged in. Then in your views access these claims from ClaimsPrincipal.Current.Claims. Have a look on my answer here that does pretty much the same, only you need to add names instead of theme.
