c# - How to check if IEnumerable is null or empty? -


i love string.isnullorempty method. i'd love have allow same functionality ienumerable. there such? maybe collection helper class? reason asking in if statements code looks cluttered if patter (mylist != null && mylist.any()). cleaner have foo.isany(mylist).

this post doesn't give answer: ienumerable empty?.

sure could write that:

public static class utils {     public static bool isany<t>(this ienumerable<t> data) {         return data != null && data.any();     } }

however, cautious not sequences repeatable; generally prefer walk them once, in case.
