复合观察

Question

我有以下代码:

Observable.FromEvent<ModelEventArgs>(
        h => ValuesController.ModelAdded += h,
        h => ValuesController.ModelAdded -= h)
    .Subscribe(m => context.Connection.Broadcast(m));

Observable.FromEvent<ModelEventArgs>(
        h => ValuesController.ModelDeleted += h,
        h => ValuesController.ModelDeleted -= h)
    .Subscribe(m => context.Connection.Broadcast(m));

什么会更清洁:

Observable.[SOMETHING](
        Observable.FromEvent<ModelEventArgs>(
                h => ValuesController.ModelAdded += h,
                h => ValuesController.ModelAdded -= h),
        Observable.FromEvent<ModelEventArgs>(
                h => ValuesController.ModelDeleted += h,
                h => ValuesController.ModelDeleted -= h))
    .Subscribe(m => context.Connection.Broadcast(m));

我似乎无法弄清楚[SOMETHING]需要什么,我不想等待ModelAdded完成,我只是希望它们都为每个事件发出(m).

对我来说很容易,我是一个Rx newb

我想你正在寻找Merge:

Observable.Merge(
        Observable.FromEvent<ModelEventArgs>(
                h => ValuesController.ModelAdded += h,
                h => ValuesController.ModelAdded -= h),
        Observable.FromEvent<ModelEventArgs>(
                h => ValuesController.ModelDeleted += h,
                h => ValuesController.ModelDeleted -= h))
    .Subscribe(m => context.Connection.Broadcast(m));
