Sorting out Nodetypes after yield in Neo4jClient

c#, neo4j, neo4jclient

Hi, for full context please check out the stackoverflow post.

The part that is relevant here:
I have this query

Match(n1: Red)
Where n1.Id = "someId"
Call apoc.path.subgraphAll(n1,{ minLevel: 0,maxLevel: 100,relationshipFilter: "link",labelFilter: "+Red|Blue"})
Yield nodes, relationships
Return nodes, relationships

It works as intended. The graph has a structure that is roughly alternating "Red" and "Blue" nodes with the same type of edge between them.

My problem is that I need to separate out the Red and Blue nodes into separate sets to make the deserialization work in C#. I think I can manage once I have the two sets separated.

So how do I use the nodes set from the yield and separate it based on node type?

In the end I want to "return Red, Blue, Relationships"

Try this:

Match(n1:Red)
Where n1.id = 1
Call apoc.path.subgraphAll(n1,{})
Yield nodes, relationships
unwind nodes as n
unwind relationships as rel
with collect(id(n)) as ID, labels(n) as lbl, count(n) as cnt, type(rel) as type
return ID, lbl, cnt, type

Result:
