我正在使用这个班级

  public   class  ApplicationUser：IdentityUser 
 {
 public   virtual  UserInfo UserInfo {获得跨度>;  set ; } 
} 
 public   class  UserInfo 
 {
 public   int  ID { get ;  set ; } 
 public   string  FullName { get 跨度>;  set ; } 

} 
 public   class  ApplicationDbContext：IdentityDbContext< ApplicationUser> 
 {
 public  ApplicationDbContext（）
： base （  AP）
 {
} 
 public  System.Data.Entity.DbSet< UserInfo> UserInfo { get ;  set ; } 
} 

和

  var  manager1 =  new  UserManager< applicationuser>（ new  UserStore< applicationuser>（ new  ApplicationDbContext（）））; 
 var  currentUser = manager1.FindById（User.Identity.GetUserId（））; 
 currentUser.UserInfo.FullName = TextBox1.Text < /   applicationuser  >  < /   applicationuser  &GT; 跨度> 

I am using this code to show user profile properties

var currentUserId = User.Identity.GetUserId();
            var manager1 = new UserManager<applicationuser>(new UserStore<applicationuser>(new ApplicationDbContext()));
            var currentUser = manager1.FindById(User.Identity.GetUserId());
            TextBox1.Text = currentUser.UserInfo.FullName;

But how can update user profile properties below code is not working

var currentUserId = User.Identity.GetUserId();
            var manager1 = new UserManager<applicationuser>(new UserStore<applicationuser>(new ApplicationDbContext()));
            var currentUser = manager1.FindById(User.Identity.GetUserId());
            currentUser.UserInfo.FullName = TextBox1.Text;

I am using this class

public class ApplicationUser : IdentityUser
    {
        public virtual UserInfo UserInfo { get; set; }
    }
    public class UserInfo
    {
        public int Id { get; set; }
        public string FullName { get; set; }
        
    }
    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("AP")
        {
        }
        public System.Data.Entity.DbSet<UserInfo> UserInfo { get; set; }
    }

and

var manager1 = new UserManager<applicationuser>(new UserStore<applicationuser>(new ApplicationDbContext()));
            var currentUser = manager1.FindById(User.Identity.GetUserId());
            currentUser.UserInfo.FullName = TextBox1.Text</applicationuser></applicationuser>
