c# - Select specific item from multi-object ViewModel -


i have viewmodel wraps 2 lists of different objects: list<review> , list<daycommentary> reviewviewmodel. list<daycommentary> collection of either 0, 1 or max 2 elements, different daycommentary.commentaryfor (string parameter) values.

in view, need display textarea 1 of elements in list<daycommentary> in 1 section of page , textarea element in section of same page.

i tried achieve code below throws error during runtime:

@html.textareafor(model => model.daycommentary.select(c => c.commentaryfor == "day"),  new {@class = "form-control commentary", @style = "max-width: none"})

error: 

templates can used field access, property access,  single-dimension array index, or single-parameter custom indexer expressions.

i assume it's not happy linq select statement.

what best way achieve i'm trying do, while still binding model posting controller during formmethod.post?

model.daycommentary.select(c => c.commentaryfor == "day")

this doesn't make sense return collection of bools.

perhaps meant

model.daycommentary.first(c => c.commentaryfor == "day").commentaryfor

if want text area each element in daycommentary collection, use foreach loop on collection. let me know if you're not sure how i'll happily add example code answer.
