ICE框架双工通讯+MVVM框架测试案例

准备

 

开发工具 VS2015

ICE框架 https://zeroc.com/

MVVMLight框架

ICE接口文件 

#include "./Identity.ice"
#include "./CommonIPC.ice"

module Demo {
    interface ServerProxy {
        void Register(Ice::Identity ident);
        int GetResultFromServer();
    };

    interface ClientProxy {
        bool SendToClient(string i);
    };
};

预编译指令 （BuildEvent）

echo Setting path for Pre-build event  > iceout.txt
set PATH=$(SolutionDir)3.6.2\;%PATH% >> iceout.txt

echo Calling slice2cs on Printer.ice >> iceout.txt
slice2cs.exe --output-dir $(ProjectDir)ICEGenerated $(ProjectDir)Printer.ice >> iceout.txt 2>&1

第一条是 预编译结果输出，成功失败异常等

第二条是开始预编译（自动生成接口文件相关）

    /// <para>
    /// You can also use Blend to data bind with the tool's support.
    /// </para>
    /// <para>

    /// </para>
    /// </summary>

            client = new MyClient();
            client.Receivedata += Client_Receivedata;

            client.Register();
            // Code runs in Blend --> create design time data.
            BackgroundWorker bg = new BackgroundWorker();
            bg.DoWork += Bg_DoWork;
            bg.RunWorkerAsync(); 
        }

        private void Client_Receivedata(object sender, System.EventArgs e)
        {
            RaisePropertyChanged("Test2");
        }

        MyClient client = null;

                Test1 = client.GetResultFromServer().ToString();
                RaisePropertyChanged("Test1");
                Thread.Sleep(5000);
            }
        }

        public string Test1
