c# - Remove items from a collection if one date is greater than another -

i'm trying use linq remove items collection 1 date greater another. know need use datetime.compare() i'm bit unsure how go it.

if allowed, code following:

cilibrary.removeall(x => x.lastsynctowebsite >= x.modified); 

since doesn't work datetime values how represent statement?

datetime values can compared using >=. need where:

cllibrary.where(x => !(x.lastsynctowebsite >= x.modified)) 

or equivalently:

cllibrary.where(x => x.lastsynctowebsite < x.modified) 

this generates new ienumerable, leaving cllibrary unchanged. if cllibrary of type list<t>, can:

cllibrary = cllibrary.where(x => x.lastsynctowebsite < x.modified).tolist(); 

if cllibrary of type t[], can:

cllibrary = cllibrary.where(x => x.lastsynctowebsite < x.modified).toarray();
