c# - blank is a 'variable' but is used like a 'method' - why am I getting this? -

i have list of cleaners (linq class) trying remove 'cleaners if unconfirmed. here code.

 list<confirmcleaner> unconfirmed = context.confirmcleaners.where(d => d.confirmed == false).tolist();                 list<cleaner> cleaners = context.cleaners.tolist();                 list<cleaner> tempcleaners = new list<cleaner>();                  foreach (var c in unconfirmed)                 {                     foreach(var r in cleaners){                          if(c.cleanerid == r.id){                              tempcleaners.add(r);                          }                     }                   }                 list<cleaner> result = cleaners().except(tempcleaners()).tolist();                 return result; 

why getting error :

'cleaners' 'variable' used 'method'

the problem line:

list<cleaner> result = cleaners().except(tempcleaners()).tolist(); 

you need change to:

list<cleaner> result = cleaners.except(tempcleaners).tolist();
