Namespace/Class/Project design questions from newbie

I am developing a set of classes to process payments for several web sites. I am planning to expose these classes to the web sites as a web service. When I call the web service to process a transaction I would like to pass it a "transaction" object, but I am confused as to how I should develop the project so that the web sites will have knowledge of the transaction object so they can instantiate the object and pass it to the web service? Any help would be greatly appreciated.

Thanks!

can you tell me which payment integration method you used?

I have yet to receive an answer to this post on this board as well as a few others. I am waiting until I have a better understanding before I start this project.

Hi,

...this can get a bit complicated too quickly, so I will just mention that you can have a web service that declares a public class like this:

VB Code:

Public Class MyClass
 
    Public hashObject As Byte()
    Public signedData As Byte()
    Public PaymentType As Integer
 
End Class

and you could have that passed to your web methods as a parameter:

VB Code:

<WebMethod()> Public Function DoSomething(ByVal MyObject As MyClass) As Integer

The class would be described to web service users by the web service definition.
