如何在ASP.NET MVC中获取新注册用户的用户ID

Question

im试图将userId存储在AspNetUsers表中，并在注册过程中将其存储在我的Student表中。

如何从AspnetUsers表中获取新创建的用户的userId（不是登录的用户），然后将其存储在期间的单独表中？

我的控制器：

public ActionResult Create(ExpandedUserDTO paramExpandedUserDTO)
{
    try
    {
        if (paramExpandedUserDTO == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        var Email = paramExpandedUserDTO.Email.Trim();
        var UserName = paramExpandedUserDTO.Email.Trim();
        var Password = paramExpandedUserDTO.Password.Trim();
        UserName = Email.ToLower();
        // Create user
        var objNewAdminUser = new ApplicationUser { UserName = UserName, Email = Email};
        var AdminUserCreateResult = UserManager.Create(objNewAdminUser, Password);
        if (AdminUserCreateResult.Succeeded == true)
        {
            string strNewRole = Convert.ToString(Request.Form["Roles"]);
            if (strNewRole != "0")
            {
                // Put user in role
                UserManager.AddToRole(objNewAdminUser.Id, strNewRole);
                //Put user in student table
                if (strNewRole == "Student")
                {

                }
            }
            return Redirect("~/Admin");
        }
    }
    catch (Exception ex)
    {
        ViewBag.Roles = GetAllRolesAsSelectList();
        return View("Create");
    }
}

Answer 1

如果创建用户为您创建ID。

 var objNewAdminUser = new ApplicationUser { UserName = UserName, Email = Email};
 var userId = objNewAdminUser.Id //18479b0a-17cd-4a76-9e9e-d90a8480617b

Answer 2

you can try this
if(AdminUserCreateResult.Succeeded == true)
{
//Get Details of currently registered User
    var RegisteredUser= SignInManager.UserManager.FindByEmail(Email);
//Extract userid from user Details.
    var userid=RegisteredUser.Id;
//this will give you the ID stored in aspnetusers of currentUser
}
