我的模型类

namespace WebApp.Models
{
    public class ExternalLoginConfirmationViewModel
    {
        [Required]
        [Display(Name = "User name")]
        public string UserName { get; set; }
    }

    public class ManageUserViewModel
    {
        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "Current password")]
        public string OldPassword { get; set; }

        [Required]
        [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "New password")]
        public string NewPassword { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "Confirm new password")]
        [System.Web.Mvc.CompareAttribute("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]
        public string ConfirmPassword { get; set; }
    }

    public class LoginViewModel
    {
        [Required]
        [Display(Name = "User name")]
        public string UserName { get; set; }

        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [Display(Name = "Remember me?")]
        public bool RememberMe { get; set; }
    }

    public class RegisterViewModel
    {

        [Required]
        [Display(Name = "First Name")]
        public string FirstName { get; set; }

        [Required]
        [Display(Name = "Last Name")]
        public string LastName { get; set; }

        [Required]
        [DataType(DataType.EmailAddress)]
        public string EmailID { get; set; }

        public int Score { get; set; }

        [Required]
        [Display(Name = "User name")]
        [Remote("CheckUserNameExists", "Common")]
        public string UserName { get; set; }

        [Required]
        [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "Confirm password")]
        [System.Web.Mvc.CompareAttribute("Password", ErrorMessage = "The password and confirmation password do not match.")]
        public string ConfirmPassword { get; set; }
    }
}

DbContextClass

namespace WebApp.Models
{
    // You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/?LinkID=317594 to learn more.
    public class ApplicationUser : IdentityUser
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Email { get; set; }
        public int Score { get; set; }
    }

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("DefaultConnection")
        {
        }

    }

}

推荐答案

创建控制器类的详细视图，让它脚手架和返回用户详细视图。导入 Microsoft.AspNet.Identity 来确定当前用户，并在你的LINQ语句中使用它
例如。

Create a detail view of your class from the controller and let it scaffold and return user detail to your view. Import Microsoft.AspNet.Identity to identify the current user and use it in your linq statement E.g.

[Authorize()]
ActionResult Details()
{
  var UserId = User.Identity.GetUserId();
  var comp = db.AspNetUsers.Where(i => i.UserName== UserId).First();

  return View(comp);
}
