ASP.NET C# - 实时通知方法

Question

你认为这是一种检索通知的坏方法吗？这个WebMethod将通过JavaScript每10秒调用一次.有没有更好的方法呢？如果是这样请详细说明.谢谢.

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public int[] GetNotifications()
{
    int[] Notifications = new int[3]{0, 0, 0};
    if (HttpContext.Current.User.Identity.IsAuthenticated) {
        string UserName = HttpContext.Current.User.Identity.Name;
        Notifications[0] = Notification.GetAll(UserName, false).Count;
        Notifications[1] = Message.GetAll(UserName, false).Count;
        Notifications[2] = Friendship.GetFriends(UserName, true).Count;
    }
    return Notifications;
}
