c# - How to query RavenDB for document containing nested object of specified type -

i have ravendb query using index , need add condition checking nested objects type (these objects aren't separate documents)

entries = session.query<result, index>()   /* conditions here */   .where(x => x.messages.any(m => m.gettype() == typeof(mymessage)))   .tolist();

raven tells me, doesn't know how translate gettype. how can achieve this?

after long research found solution.

i added field index:

messagetypes = entry.messages.select(m => asdocument(m)["$type"].tostring())

asdocument() returns ravenjobject contains properties including $type. property indexed, asking type quite simple
