推荐答案

试试这个以获得可观察的读取键序列:

Try this to get an observable sequence of read keys:

        IObservable<System.ConsoleKeyInfo> keys =
            Observable
                .Defer(() =>
                    Observable
                        .Start(() =>
                            Console.ReadKey()))
                .Repeat();

我对此进行了测试，效果很好.

I tested this and it worked like a treat.
