If some method requires an ICollection<T>
as an argument, but I have only an IEnumerable<T>
available: Is it better to convert this IEnumerable<T>
to a IList<T>
or is it better to convert it to an array T[]
or shall I convert it to something else or is there no difference at all?
The IEnumerable<T>
is only required for this method call, so no further read/write/extend is required.
