c# - Iterating through an observable list? -

-

I inherited an API that accesses remote (real-time) JSON via viewable subscription.

In large part, lots of members are just strings and doubles, but there are some lists and I have zero thought about how to repeat them through linq / takewhile and subscribe to the methods. 

  mcsub.TakeWhile (p = & gt; p.Status == Market.OPEN). Subscribe (X => Console WrightLine (DateTime.Now.Second + "-" + mc.Event.Name + "-" + x.Items [0]. Prices));

Where x is a list, how will I be repeated in a single statement to display the prices of all items?

Thanks in advance. 

  mcSub.TakeWhile (p = & gt; p.Status == Market.OPEN ). Subscribe (x = & gt; x.Items.ForEach (y = & gt; console.writeLine (DateTime.Now.Second + "-" + mc.Event.Name + "-" + y. Value)));

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
