c# - Lambda Except Placement -


i want return list of lans , want exclude userinformation.globals.lanid list.

code:

var lanlist = _context.corp_matrixpositionoldway                .where(x => x.childorglevel.startswith(parentorg.tostring()))                .select(x => x.childlan)                .except(userinformation.globals.lanid);

error:

'iqueryable' not contain definition 'except'

i think want exclude single childlan, use where:

var lanlist = _context.corp_matrixpositionoldway            .where(x => x.childorglevel.startswith(parentorg.tostring()))            .select(x => x.childlan)            .where(lan => lan != userinformation.globals.lanid);

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
