ToList() on a list

Filed under: Uncategorized — andreakn @ 09:47

I usually add this little gem in my projects:

public static List<T> ToList<T>(this List<T> list)
return list;

so that calling ToList on something that is already a list doesn’t require looping through all the content (which is the default implementation of IEnumerable[t].ToList())

I also tend to put it into the System.Linq namespace so that it comes automatically when I get the original method. (i know it’s not the recommended way, but GOD it’s so practical)

premature optimization is the root of all evil, but small invisible ones isn’t (imho)
