I have a web method in my web service that I would to have a command object
passed in as a parameter. But when I compile the service I get the following
error:

You must implement the Add(System.Data.DataRowView) method on
System.Data.DataView because it inherits from ICollection.

If I replace the parameter's data type to a string, it compiles. Do web
services only allow certain data types to be passed to web methods?

Hello Will,
As far as I can see this problem is not related to web services at all. You just have to implement ICollection::Add method probably to get your object serialized.

How would I go about doing that, I'm a newbie to web services.

Thanks,

Will

Hi Will,

Open Class View (Ctrl+Shift+C) and locate your class. Expand it using the plus sign and locate the interface ICollectable. Right click over its method Add and choose Add/Override in the menu.
As I said this is not web service related issue so you may first try posting to other newsgroups.
