User.Identity.Name full name mvc5

Question

I've extended the ASP NET identity schema by adding few fields in the ApplicationUser Class which is derived from IdentityUser. One of the field that I've added is FullName.

Now, when I write User.Identity.Name, it gives me the user name, I m looking for something like User.Identity.FullName which should return the FullName that I have added.

Not sure, how this can be achieved any guidance shall be greatly appreciated.

Thanks.

In the ApplicationUser class, you'll notice a comment (if you use the standard MVC5 template) that says "Add custom user claims here".

Given that, here's what adding FullName would look like:

public class ApplicationUser : IdentityUser {     public string FullName { get; set; }      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         userIdentity.AddClaim(new Claim("FullName", this.FullName));         return userIdentity;     } } 

Using this, when someone logs in, the FullName claim will be put in the cookie. You could make a helper to access it like this:

    public static string GetFullName(this System.Security.Principal.IPrincipal usr)     {         var fullNameClaim = ((ClaimsIdentity)usr.Identity).FindFirst("FullName");         if (fullNameClaim != null)             return fullNameClaim.Value;          return "";     } 

And use the helper like this:

@using HelperNamespace ... @Html.ActionLink("Hello " + User.GetFullName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" }) 

Note that custom user claims are stored in the cookie and this is preferable to getting the user info from the DB... saves a DB hit for commonly accessed data.
