vb.net - Concatenate IQueryable starting with Empty IQueryable in VB -
i trying concatenate multiple linq requests returns (all returns iqueryable).
my problem need start empty iqueryable variable, ".concat" method doesn't work variable "nothing".
i wondering if had way of doing this?
ps: can use multiple "where" requests "and" not "or" (seq.where(seq.where())). trying latter concatenating multiple requests. also, if impossible request (a request returning no match), works, not idea.
thank anyway. have nice day.
finally had request once on first item of list, remove item. after that, each (using "contains" query database).
still, not answer think. pretty looks hack.
i did not find way to query linq.
i querying database using contains
, verifying if x in database. had to list of x.
