在您的情况下，这可能可行

In your case maybe this could work

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Register(RegisterViewModel model, string returnUrl = null)
{
    ViewData["ReturnUrl"] = returnUrl;
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser { UserName = model.Email, Email = model.Email 
        var result = await _userManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            await _signInManager.SignInAsync(user, isPersistent: false);
            return LocalRedirect(returnUrl);
        }
        AddErrors(result);
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}
