networkcomms3.0 How to implement analog login code sharing in C #

This article mainly introduces the C # Networkcomms 3.0 implementation of the simulation landing summary, the need for friends can refer to the following

Recently the project needs to do a customer query status system, the current host computer lacks the service function, so found the Networkcomms open source framework, as a project use.

Message = resmsg; Connection.        Sendobject<resmsgcontract> ("Reslogin", contract);        Resmsgcontract contract = new resmsgcontract (); Contract.        Message = resmsg; Connection.      SendObject ("Reslogin", contract);      } catch (Exception ex) {//Logtools.logexception (ex, "Incomingmsghandle"); }    }  }}

This line is often missing from other help: There was a problem with the type packaging when the client was sent. This line of code is added on both sides of the client server, and is the specified transfer mode

Sendreceiveoptions aboveoptions = new Sendreceiveoptions (dpsmanager.getdataserializer<protobufserializer> (), NULL, NULL);

That's the error.

Contract class

Using system;using system.collections.generic;using system.linq;using system.text;namespace MessageContract{  [ Protocontract] public  class Logincontract  {    [Protomember (1)] public    string UserID {get; set;}    [Protomember (2)]    public string PassWord {get; set;}    Public logincontract () {} public    Logincontract (string UserID, String PassWord)    {this      . UserID = userid;      This. PassWord = PassWord;}}  } Using protobuf;using system;using system.collections.generic;using system.linq;using System.Text;namespace messagecontract{  [protocontract] public  class Resmsgcontract  {    [Protomember (1)]    public string Message;    Public resmsgcontract () {} public    Resmsgcontract (String message)    {this      . message = Message;}}}  

Attention:

Use this framework to match Google's protobuf to choose a good version. I did not repeat the highest version of the test, because during the debug logon process during the process of other problems, also changed the version of PROTOBUF, has not tested the highest version of whether there is compatibility problem. I successfully use the 2.0.0.668

Protobuf Introduction Protobuf is an open-source serialization framework provided by Google, similar to the data representation language of Xml,json, which is most characteristic of binary-based, and therefore less efficient than traditional XML representations

VS NuGet Add Way

Input

Version choose to specify, increase the project contract class inside. This is how you define the Transfer object.

The above is a small series to introduce you to the C # Networkcomms 3.0 to achieve the simulation landing summary, I hope that we have some help, if you have any questions please give me a message, small series will promptly reply to you. Thank you very much for the support of the Scripting House website!
