name value collection in a web service

Question

with .Net v2 (moving to WCF eventually), what datatype do i use for passing name/value collections thru web services?  I know that hashtable doesnt work, but what should be used?  is there a new generic type that implements IXmlSerialible to use?  do i need to stick with a ArrayList of my own type? 

thanks.

Answer 1

WCF supports serializing Hashtable but if you want a type that also works with ASMX you should use an ArrayList (or array) of your custom type that has name and value fields.

 

Answer 2

I like to use List<T> to expose strongly typed arrays in service interfaces.
