I have a current requirement to all a subsidiary to use a current legacy
application and interface with my new system to inject data when appropriate.
I wanted to create a web service since we are both .Net shops and this would
seem to be the easiest method. But I ran into one snafu. I wanted to return
to the subsidiary an ArrayList of my Organization objects which contain the
orgs id, name etc. so they can use that information in the data insert call.

I have done a lot of looking around but have not found the answer yet to
accomplish this. Here is some of the code:

1. Web service calls an object manager which returns the ArrayList:
1. ArrayList _array = ObjectManager.Instance.GetAllOrgs();
2. Object manager calls the object data store returning ArrayList
1. ObjectStore.Instance.GetAllOrgs();
3. Object store makes database call, passes reader to method that loops
over results building an Org object and adding it to an array.:
1. public ArrayList GetAllOrgs()
{
ArrayList orgs = new ArrayList();

using (SqlConnection connection = new
SqlConnection(_connectionString))
{
connection.Open();

SqlCommand command = new SqlCommand();

command.Connection = connection;
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "usp_GetOrgs";

SqlDataReader reader =
command.ExecuteReader(CommandBehavior.SingleResult);

orgs = CreateOrgs(reader);

}

return orgs;
}

That is my issue in a nutshell - my web page that consumes the web service
does not know how to cope with the ArrayList with Org objects in it.

Any help would be much appreciated!

Try using a basic array, rather than an ArrayList.

--

use the following attributes for your webmethod

[XmlInclude(typeof(ArrayList))]
[XmlInclude(typeof(Org))]
