c# - ObservableCollection Enumerator with filter -

-

i need filter out items observable collection. previously, ienumerable, doing:

private ienumerable _mycollection {get; set;} public ienumerator<mytype> getenumerator() {    var filteredtype = _mycolletion.where(t => t.myproperty.state != states.needsdelete); return filteredtype.getenumerator(); }  system.collections.ienumerator system.collections.ienumerable.getenumerator() {    return getenumerator(); }

i'm using observablecollection. how implement same thing?

edit (context):

i'm keeping track of entities, working them in memory, , idea that, @ end, push these entities web service. each object in observable collection have state, such "needscreate", "needsdelete", "needsupdate" or unchanged. then, go through each of these states , call appropriate web service synchronize these changes.

well observalbecollection inherit collection , on ienumerable. "exact same way" be:

var collection = new observablecollection<type>(); public ienumerator<type> getenumerator() {     return collection         .where(i => i.property.state != states.needsdelete)         .getenumerator(); }

maybe i'm interpreting wrong way. you're trying achieve?
