I need a server/client in c# in modality always-on, based on socket, that send a struct and receive an answer struct. public struct message_header { public byte versione; public UInt16 id_fsc; public uint id_cn; public uint id_pvend; public ushort id_tag; public byte tipo_tag; public ushort lung_body; public ushort lung_ae; public byte[] id_transazione = new byte[8]; public ushort id_servizio; public byte id_messaggio; public byte[] liberi = new byte[3]; // id_transazione is a long number transformed in byte[8] } * the client must fill the struct data with an external function that will be created later. * the server must take the same structure data and must give me all the single data.

As discussed: This is very risky project and there is potentially a lot of issues with it, what can I propose is something like that: Single service which will implement both - Client and Server logic, due the fact that there is no way to test that service I’ll create my own echo server which will be “external server” it will get data from client and send it back to the server. Also as I don’t have any test data source which can be used server will read sample data from sample file (base64encoded binary data structure). Those data will be send in infinite loop to show that service works. Additionally there will be simple service installer created at the end of project. As this project involves more work like installer plus I need to create test each server it will take a bit longer I still assume that it will be a one day of development and half of day for testing. Final cost of the project will be 250 euro, Paid in two milestones first milestone after providing screencast from my test system (150 euro) and second (100 euro) after software installation on target machine. Source code will be provided after both milestones.

Hi there, I read your project and it is interesting (and simple). I've built many applications to communicate remotely via TCP or UDP in either way it is practically the same when you have to send raw data or encapsulated in a structure, but the principle is still the same, there are actually no variations. I am an IT engineer and I work exclusively with .NET projects. In your specific case, it is quite simple. Even though you still do not specify if you need a prototype of C# Client/Server to handle this structure or if you already have a system Client/Server and want to handle the sending/receiving of structured data. Anyhow, in the end it would be the same and I can build your project as a stand alone or embedded in another existing project you are currently working on. There is not much to say actually, your project is clear and straightforward. I placed 3 days on my bid, 2 days to deliver your solution and 1 more just in case you need any adjustment or modification. Well, I think that is all. If you have any question just send a message. Regards, Joe.

I have previously worked with marshaling data streams into structs, by adding StructLayout and MarshalAs properties to the struct then using the marshaller to copy the data to a struct instance. That's really the only thing that needs to be added to the generic synchronous or asynchronous sockets examples that microsoft provides.
