有没有办法跟踪反应命令何时完成执行? [英] Is there a way to track when reactive command finished its execution?

问题描述

有谁知道如何跟踪响应式命令已完成执行并连接方法，该方法将在此之后开始运行?

Does anybody know how to track the fact that reactive command has finished its execution and hook up the method, which will start running after that?

附言在命令处理程序方法的末尾调用方法时的变体不适合我的情况.

P.S. The variant when calling the method in the end of the command's handler method does not fit in my situation.

提前致谢！

推荐答案

ReactiveCommand 有一个名为 IsExecuting 的可观察属性，可用于观察命令何时执行.处理这种情况的一种方法是做这样的事情:

ReactiveCommand has an observable property called IsExecuting that can be used to observe when the command is being executed. One way to handle this case would be doing something like this:

YourCommand.IsExecuting
    .Skip(1) // IsExecuting has an initial value of false.  We can skip that first value
    .Where(isExecuting => !isExecuting) // filter until the executing state becomes false
    .Subscribe(_ => YourMethodCall()); // run your method now that the command is done
