How to get List from observable GroupBy list?
0
I just starting using Rx for .NET and i am facing couple of issues with GroupBy Operator.
Data --> byte
How can i get list of Data (List) for each group ?
var group = driver.Frames
.Where(x => x.Data[0] == 0x08)
.GroupBy(x => x.Data[7]);
group
.SelectMany(x => x)
.Select(x => x.Data)
.SubscribeConsole();
c# group-by system.reactive

Is this really Reactive Extensions or Linq? Because this looks like Linq...

There's no point doing a.GroupBy(x => x.Data[7]).SelectMany(x => x)- it effectively returns the original observable. Are you just wanting.GroupBy(x => x.Data[7]).Select(x => x.ToList())? For that to work, you needdriver.Framesto complete. Does that happen?

yes .. i need.GroupBy(x => x.Data[7]).Select(x => x.ToList())?but the issue that driver.Frames won't complete and each group created as observable and waits any new item match this group ... the condition here that i don't know how to implement is after timeout delay if there is no new emits to group mark this group as completed .. how can reach something like this ?
