I need to bring back a generated key-value set/table... its not from the database<BR><BR>a HastTable would be perfect, but that is apparently not a returnable type from a web service.....<BR><BR>So i am looking for one of the following few things:<BR>- Some site with a list of valid types from a WebMethod() Function<BR>- Some way to create a DataSet from scratch (i know how to create a DataTable, is there a way to go from DataTable to DataSet?)<BR>- Any other ideas... looking in ASP Unleashed here, they return an array of class objects... but how does the client site know about this Namespace? (really not sure if that .vb file is part of the client or the web service)
