Solution 1

The same way you send and receive anything. You just need your client and server to understand the format of the data that you are transferring. If it is fixed length records than that is easy. If it is variable length then you just need to include extra information to show the length of the data.

I dont think its that simple. So if you are sending Name, Address, as string, and Amount as integer in one record, you just pack them together? I know it should have something to do with objects of a class

Yes but an object has no meaning in network transfer, all you are sending is a stream of bytes, some of those bytes will represent strings, some will represent integers, some will represent DateTime values etc. The only issue is that the client and server both agree on the structure of the data.

@Richard thanks, I have heard of some object serialization, maybe i should look into it. it should be easier. Thanks.
