How to send a Object from server to client

Question

Hello,

I'am writing a server/client application in vb.net.
Now, what i would like to do is build a server application that fills a database with dataobjects recieved from a client and keeps other clients up to date with the changes that are made in the database.

I can send strings from client to server and back, but i can't find a way to send an object from client to server.

By example

I have an object called Person with a few properties.
I would like to send a list of new person objects from the client to the server so that the server can store them into the database.

Anyone have an idea??

thanks
