DNN通知API

Question

我正在使用DNN 6.2並嘗試創建通知，但由於我是新手，所以不太瞭解API。

文檔建議以下

NotificationsController.Instance.SendNotification(
    notification, 
    PortalSettings.PortalId, 
    new List<RoleInfo>(), // Pass here the list of roles or null if the notification is going to be sent to individual users only. 
    new List<UserInfo>(), // Pass here the list of users or null if the notification is going to be sent to roles only. 
); // There is an overload that doesn't receive this parameter and uses Admin as sender. 

我已經定義並與用戶id填充列表

private List<string> listOfFriends = new List<string>(); 

所以我雖然下面將工作

NotificationsController.Instance.SendNotification(notification, PortalSettings.PortalId,"", listOfFriends); 

但我出現錯誤'有一些無效的論點。

我在做什麼錯？

Answer 1

您是否得到了這個工作？

我覺得這

NotificationsController.Instance.SendNotification(notification, PortalSettings.PortalId,"", listOfFriends); 

應該

NotificationsController.Instance.SendNotification(notification, PortalSettings.PortalId, **null**, listOfFriends);
