I love string.IsNullOrEmpty
method. I'd love to have something that would allow the same functionality for IEnumerable. Is there such? Maybe some collection helper class? The reason I am asking is that in if
statements the code looks cluttered if the patter is (mylist != null && mylist.Any())
. It would be much cleaner to have Foo.IsAny(myList)
.
This post doesn't give that answer: IEnumerable is empty?.
Sure you could write that:
public static class Utils {
public static bool IsAny<T>(this IEnumerable<T> data) {
return data != null && data.Any();
}
}
however, be cautious that not all sequences are repeatable; generally I prefer to only walk them once, just in case.
