I'm Trying, pass a long array for a named query (native SQL) for to use in an IN STATEMENT: Like this:
(...) WHERE Identificator IN (:pIdes)
I tried pass my ides as long[]:

ctx.GetNamedQuery("NamedQueryName")                                          
                   .SetParameter<long[]>("pIdes", Identificators)
                   .List<EmpreendimentoInputReport>();

and as a string

ctx.GetNamedQuery("NamedQueryName")                                          
                   .SetParameter<string>("pIdes", Identificators)
                   .List<EmpreendimentoInputReport>();

When the parameter is a string return nothing, whem is a long[] return this Oracle error:
"Oracle.DataAccess.Client.OracleException: ORA-00932: tipos de dados inconsistentes: esperava NUMBER obteve BINARY"
