如何在MVC中的OpenID-Connect中执行重定向前的操作

Question

我已经试了好几天了，但是不能弄明白，如果有人能帮到我，我将不胜感激。

public void SignIn()
        {
            // Send an OpenID Connect sign-in request.
            if (!Request.IsAuthenticated)
            {

                //Perform some action if user is successfully authenticated??

                HttpContext.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "https://localhost:44309/DummyController/DummyAction" }, OpenIdConnectAuthenticationDefaults.AuthenticationType);
            }

        }

实现动作RedirectToIdentityProvider

  Notifications = new OpenIdConnectAuthenticationNotifications
            {
                RedirectToIdentityProvider = OnRedirectToIdentityProvider
            }

   private Task OnRedirectToIdentityProvider(RedirectToIdentityProviderNotification<OpenIdConnectMessage, 
        OpenIdConnectAuthenticationOptions> arg)
    {
        throw new NotImplementedException();
    }
