What's more efficient in .Any and .Count in C# (Extension methods)

public void MethodName(ObservableCollection<DataCollection> dataCollection)
{
if (dataCollection != null)
{
IsChecked = dataCollection.Any(o => o.DataCollectionID.Equals(30));

IsChecked = dataCollection.Where(o => o.DataCollectionID.Equals(30)).Count() > 0;
}
}

Can anyone explain me, what could be the most efficient way to use from above two filtering? .Any? or .Where.Count?

Note: Consider that dataCollection has over 10,000 items.

Please advice me. Thank you

hope .count is more efficient. Any will compare with each case.not sure

Oya use karana wadedi .Any eka hodai .Where ekata wada.
.Any use karama collection eke ekak hari pass una gaman true value ekak return wenawa. .Where use karahama apita adala predicate eken filter una list ekak labenne. Ita passe apita Count operation eka ekkama IF condition ekakuth use karanna wenawa additional opereations widihata.
