Cannot serialize interface System.Data.IDataReader 1

[ksbigfoot]

I am trying to create a webservice and pass back to my combobox an IDataReader.
When I try to run the service, I get this in my webpage: "Cannot serialize interface System.Data.IDataReader". Can I use a DataReader or does it have to be XML or something like that?
Could someone point me in the right direction.
Thanks

Yes, you will get that error if you try to return any interface as it's XML that is returned from a web service and interfaces don't really have any correlation to XML. You should be able to use of the the base classes though (System.Data.DataTable, System.Data.DataReader etc).

Thanks ca8msm,
Star to you. I was able to get it working using a DataTable.
