What is the most efficient way of converting a single column linq query to a string array?
private string[] WordList()
{
DataContext db = new DataContext();
var list = from x in db.Words
orderby x.Word ascending
select new { x.Word };
// return string array here
}
Note - x.Word is a string
I prefer the lambda style, and you really ought to be disposing your data context.
private string[] WordList()
{
using (DataContext db = new DataContext())
{
return db.Words.Select( x => x.Word ).OrderBy( x => x ).ToArray();
}
}
How about:
return list.ToArray();
This is presuming that x.Word
is actually a string.
Otherwise you could try:
return list.Select(x => x.ToString()).ToArray();
if you type it in Lambda syntax instead you can do it a bit easier with the ToArray method:
string[] list = db.Words.OrderBy(w=> w.Word).Select(w => w.Word).ToArray();
or even shorter:
return db.Words.OrderBy(w => w.Word).Select(w => w.Word).ToArray();
