C#异步调用方法

此类 unit 具有一个属性 bool status ，该属性标记是否应在该单元上调用方法 request .我有另一个类，并且在其中有一个应调用 request 的方法.为了避免阻塞主线程，我想异步调用该方法.问题在于状态更改没有事件，并且我不想让异步调用执行类似以下的丑陋事情:

There is this class unit that has a property bool status that marks whether a method, request, should be called on the unit. I have my other class, and in it, there is a method that should call request. To avoid blocking the main thread, I want to call the method asynchronously. The problem is that there isn't an event for the status change, and I don't want to make my asynchronous call do ugly stuff like:

while(!status){}unit.request(args);

或

while(!status){Thread.Sleep(100)}unit.request(args);

尤其是当我不知道状态变为 true 的时间表时.

especially when I do not know the timescale in which status turns true.

我该怎么做?

更新:我忘了提到我不能更改 unit .对此感到抱歉.

update: i forgot to mention that i cannot change unit. sorry for that.
