List of strings to one string

Question

Lets say you have a   List lt string gt  los   new List lt string gt       In this crazy functional world we live in these days which one of these would be best for creating one string by concatenating these   String Join String Empty  los ToArray      StringBuilder builder   new StringBuilder    los ForEach s   gt  builder Append s     string disp   los Aggregate lt string gt   a  b    gt  a   b     or Plain old StringBuilder foreach  OR is there a better way

string Concat los ToArray       If you just want to concatenate the strings then use string Concat   instead of string Join

My vote is string Join  No need for lambda evaluations and temporary functions to be created  fewer function calls  less stack pushing and popping

los Aggregate  current  next    gt  current         next

If you use  net 4 0 you can use a sorter way   String Join lt string gt  String Empty  los

I would go with option A   String Join String Empty  los ToArray       My reasoning is because the Join method was written for that purpose  In fact if you look at Reflector  you ll see that unsafe code was used to really optimize it  The other two also WORK  but I think the Join function was written for this purpose  and I would guess  the most efficient  I could be wrong though     As per  Nuri YILMAZ without  ToArray    but this is  NET 4    String Join String Empty  los

String Join   is implemented quite fast  and as you already have a collection of the strings in question  is probably the best choice  Above all  it shouts  I m joining a list of strings   Always nice
