我的应用程序是MVC5,我尝试使用以下内容允许重复的电子邮件地址:

public async Task<ActionResult> AddUser (UserRegisterViewModel userViewModel)
        {
       ......
            if (ModelState.IsValid)
                {
                var user = new ApplicationUser
                {
               ......
                };
                var adminresult = await UserManager.CreateAsync(user);
                var result = await UserManager.AddToRolesAsync(user.Id, user.Profession);
                UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager)
                {
                    RequireUniqueEmail = false
                };
                if (adminresult.Succeeded)
                    {
                     ....
                    return RedirectToAction("VisitInfo", "Visit");
                    }
                if (!adminresult.Succeeded)
                    {
                    var er = adminresult.Errors.FirstOrDefault();
                    ViewBag.Error = er;
                    return View(userViewModel);
                    }

                    return RedirectToAction("VisitInfo", "Visit");
                }               
            return View();
            }

添加RequireUniqueEmail = false。它没有用,页面被重定向到登录页面!! 我的问题是,我是否可以仅为此操作允许重复的电子邮件,以及为什么我会被重定向到登录页面?

如果您使用默认的MVC 5项目模板,正确的方法是在IdentityConfig.cs 而不是在注册控制器中设置规则。

打开App_Start\IdentityConfig.cs并修改此行:

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
{
    var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
    // Configure validation logic for usernames
    manager.UserValidator = new UserValidator<ApplicationUser>(manager)
    {
        AllowOnlyAlphanumericUserNames = false,
        RequireUniqueEmail = false  //<-- the default is true
    };

    ....<snip>....

感谢Brendan,我感动了

            UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager)
                {
                    RequireUniqueEmail = false
                };

在:

 var adminresult = await UserManager.CreateAsync(user);

您必须在configureservices中添加以下行

 services.AddIdentity<ApplicationUser, IdentityRole>(options =>
            {
                options.User.RequireUniqueEmail = false;

            })
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();
