Web Method, datatable, but send as standard types, string array

[John Sitka]

Hi,

I'm building a simple "look up" web method that would return
a table with 9 columns and a dynamic number of rows,
then I find out datatables cannot be serialized.
Not a big deal the .Net 1.1 client works with dataset.
But it got me thinking that I might as well deliver this in
a neutral format, since it's such a terribly simple return set I figured
use standard types and that would mean a 2 dimensional
string array. (rather than a Custom type such as Array of objects)

How to do this?

Just return an array of a struct that has all of your 9 columns. That is
perfectly platform-neutral.

Thanks

>That is perfectly platform-neutral.

I've read some of your critique about the ultimate goal of a service
Agnostic and durable, and the "training wheels" of VS.NET.
Would you have a wdsl signature of such an struct array,
or point me to a web service that does.
