推荐答案

我建​​议你调查使用EventAggregator（ Prism EventAggregator Sample [ ^ ]）。您希望有一个控制器，它将为每个UserControl Update提供特权。因此，将EventAggregator消息发送到请求控制的控制器，然后控制器将使用另一个EventAggregator消息授予该请求。当用户控件完成时，它会向控制器发送一个EventAggregator消息，释放令牌（可以这么说）。等等。

I would suggest you investigate using an EventAggregator (Prism EventAggregator Sample[^]). You want to have a controller that will give each UserControl Update privilages. So, an EventAggregator message is is sent to the controller requesting control, then the controller will grant the request with another EventAggregator message. When a user control is finished, it sends an EventAggregator message to the controller releasing the token (so to speak). etc. etc.

请在窗口中显示两个用户控件的示例

please a sample with two usercontrol in on window
