我正在使用 ReactiveCommand 来获取异步行为.根据 Paul Betts 在本次讨论中的评论

I am using ReactiveCommand to get Async behavior. According to Paul Betts comment in this discussion

如果您使用的是 RxUI 5.0，只需使用 ReactiveCommand，它们现在已合并并具有更好的 API.

If you're using RxUI 5.0, just use ReactiveCommand, they are now merged and have a better API.

我有以下代码来测试它是否执行异步行为.事实证明并非如此.它会冻结 UI 5 秒钟.

I have the following code to test to see if it does the Async behavior. And it turns out to be not. It freezes up the UI for 5 seconds.

MyReactiveCommand.Subscribe(s => { Thread.Sleep(5000); });

我错过了什么?

推荐答案

尝试:

MyReactiveCommand .RegisterAsyncAction(_ => { Thread.Sleep(5000); });

如果你需要返回一个结果:

And if you need to return a result:

MyReactiveCommand .RegisterAsyncFunction(o => { Thread.Sleep(5000); return o.ToString(); }) .Subscribe(s => MessageBox.Show(string.Format("{0} was returned", s)));
