Using LINQ to see if Item already exists in listview

[Gaz]

Im trying to use c# and linq to simplfy searching through a listview
but cannot get it to work can anyone help?
here is what i got so far which doesnt work.

var qry = from L in listviewname.it ems.all

where l.item.value == "123"

Select L.item.value;

Thanks Gary

ok i will start again...

Im trying to learn LINQ and im not sure if im going about this in the
correct method.

I want to query all the items in the listview collection where the
item key value in the collection is equal to what i tell it..

This is my code..

var qry = from itm in uListSelected.I tems
where itm.key == "1"
Select itm.key;

foreach (var Result in qry)
{
return true;
}

Is this bit more helpful?

its to replace this
foreach(Infragi stics.Win.Ultra WinListView.Ult raListViewItem Itm in
uListSelected.I tems)
{

if (KeyID == Convert.ToStrin g(Itm.Key))
{
return true;

}

}
