C # networkcomms 3.0 implements simulated login summary,

Recently, a customer query status system is required for the project. The current PC lacks service functions, so the networkcomms open-source framework is found and used as a project.

Create a server

This line of code is often missing in other help scenarios: as a result, a type packaging problem occurs when the client sends messages. This line of code is added at both ends of the client server and is used to specify the transmission mode.

 SendReceiveOptions aboveOptions = new SendReceiveOptions(DPSManager.GetDataSerializer<ProtobufSerializer>(), null, null);

This is the error.

Here is the client.

Contract type

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;        }    }}

 

Note:

This framework should be used with Google's protobuf to select a proper version. I did not repeat the test of the highest version, because the protobuf version was changed when other problems occurred during the debugging and login process. So far, I have not tested whether the highest version is compatible. I successfully used 2.0.0.668.

Protobuf introduction protobuf is an open-source serialization framework provided by google. It is similar to a data representation language such as XML and JSON. Its biggest feature is that it is based on binary, so it is less efficient than the traditional XML Representation.

Select your own version to add the contract class of the project. This is your own way to define the transmission object.
