String to integer Array

I was interested in performant as I now have comparative
figures if
speed becomes an issue greatly appreciated.

perhaps I misunderstood you .. I thought you asked for the
most
performant
way of doing this ..

split: 00:00:04.3906250
iterate: 00:00:00.5000000
delegate: 00:00:04.9843750
unsafe: 00:00:00.3750000

Oh well, its an interesting blog post.

Cheers,

Greg Young

Cool!
Instead of delegating to an inline method, you can delegate
to an existing
framework method ;o)

int i[] = Array.ConvertAll<string,
int>(commadelimitedInts.Split(new string[]
{ "," }, StringSplitOptions.RemoveEmptyEntries),
new Converter<string, int
>(System.Convert.ToInt32));
