Ez LINQ Noob Question

How can I make this return a true/false? Is there a way to clean this up without adding a .Count() > 0 call?

bool onlyContainsQuarters = allDates.Where(x => quarterEndMonths.Any(prefix => x.StartsWith(prefix)));

bool onlyContainsQuarters = allDates.Where(x => quarterEndMonths.Any(prefix => x.StartsWith(prefix)));

quarterEndMonths is a hashset of prefixes.

Would this not work?:

bool onlyContainsQuarters = allDates.Any(x => quarterEndMonths.Any(prefix => x.StartsWith(prefix)));

bool onlyContainsQuarters = allDates.Any(x => quarterEndMonths.Any(prefix => x.StartsWith(prefix)));

replace Where with Any i think
