Question

TcpClient - TcpListener/Server WPF application for logging and testing

Markus Freitag 3,791

Hello,
I'm looking for a good example of a Client / Server Socket application to be able to check interfaces/messages.

Example I am the client. The server sends a request to the client. The client answers the question. The UserInface should not block. Or vice versa, the client asks the server.

Two apps, inteface is a XML request and XML response. (or string message)

Idea

Thanks for help.

It's called full duplex. This is easily achievable with WCF duplex. The service can be a WCF selfhosting exe program.

WCF data exchange default is XML.

Thanks for the quick response. I need no web. I have only a WPF desktop application.

A WCF selfhosting service is a programname.exe file type that runs on the Windows desktop. It in no way is a Web program. :)

public class FoodAnswer
      {
          public bool Result { get; set; }
          public string ErrorCode { get; set; }
          public string ErrorMessage { get; set; }
      }

wcf_self_hosting.htm

//Create a URI to serve as the base address
         UrihttpUrl = newUri("http://localhost:8090/MyCalculatorWCFService/SimpleCalculator");

Can you tell me how to modify the example to get the FoodAnswer object back? Request with POST.

   //Create ServiceHost
             ServiceHost host = newServiceHost(typeof(MyCalculatorWCFService.ISimpleCalculator), httpUrl);

Thanks in advance.

You need to create a datacontract.

Also, you should be posting to the Q&A WCF tag where you can get the help needed.

Yes, thanks, looks good.

When I send a post request, how do I do it?

I have no function.

Maybe it should come up on the website. How should I enter this?

http://localhost:8085/
http://localhost:8085/GetStudent?
http://localhost:8085/ Get or Post?

You're not using a Restful client that is using WCF, with Restful verbs such as Post. You are using a WCF client that is communications with a WCF service using the appropriate network protocol, which would be NetTCPBinding.

https://www.c-sharpcorner.com/UploadFile/0c1bb2/consuming-wcf-service-in-console-application/

Again, I advise you to post to the Q&A WCF tag so they can guide you as to what you need to be doing to be successful in using WCF duplex or not.
