Eplan-行为

Eplan-行为

初始化

想要在Eplan中实现行为的方法，则需要实现 IEplAction 接口，重写Execute（）和 OnRegister（）方法。

Execute()方法中为执行的逻辑，

OnRegister()中为行为在方法中注册的名称，若不注册，则为类的名称。

  public class ActionParamAction : IEplAction
    {
        public bool Execute(ActionCallingContext oActionCallingContext)
        { 
            return true;
        }

        public void GetActionProperties(ref ActionProperties actionProperties)
        {
           
        }

        public bool OnRegister(ref string Name, ref int Ordinal)
        {
            return true;
        }
    }

实现场景

行为在Eplan中一共有三种调用方式

1. 菜单项调用
2. 行为调用行为
3. 远程调用行为

菜单项调用

在菜单中绑定行为的名称可以点击触发行为

   public void InitMenu()
        {
            Menu menu = new Menu();
            uint menuNum = menu.AddMainMenu("附加菜单栏", Menu.MainMenuName.eMainMenuHelp, "BoxDevice", "BoxDeviceAction", "", 1);
            menu.AddMenuItem("调用行为", "ActionParaAction", "", menuNum, 1, true, false);
           menu.AddMenuItem("action调用action", "ExecuteAction", "", menuNum, 1, true, false);
        }
public class ActionParamAction : IEplAction
    {
        public bool Execute(ActionCallingContext oActionCallingContext)
        {
            return true;
        }

        public void GetActionProperties(ref ActionProperties actionProperties)
        {
           
        }

        public bool OnRegister(ref string Name, ref int Ordinal)
        {
            Name = "ActionParaAction";
            Ordinal = 20;
            return true;
        }
    }

行为调用行为

行为调用行为的方式，需要actionmanger通过名称找到行为，然后调用

  internal class ExecuteAction : IEplAction
    {
        public bool Execute(ActionCallingContext oActionCallingContext)
        {
            // 查找
            ActionManager manager = new ActionManager();
            Eplan.EplApi.ApplicationFramework.Action action = manager.FindAction("ActionParaAction");
            // 赋值
            ActionCallingContext ctx = new ActionCallingContext();   
            // 执行
            action.Execute(ctx);
            return true;
        }

        public void GetActionProperties(ref ActionProperties actionProperties)
        {

        }

        public bool OnRegister(ref string Name, ref int Ordinal)
        {
            Name = "ExecuteAction";
            Ordinal = 20;
            return true;
        }
    }

在此过程中需要注意，action还有传参和出参，相当于方法中的传参和返回值，这些都要借助于ActionCallingContext这个类来实现

  public class ActionParaAction : IEplAction
    {
        public bool Execute(ActionCallingContext oActionCallingContext)
        {
       		string value1 = "";
            string value2 = "";
// 接收传入的参数
            oActionCallingContext.GetParameter("Param1", ref value1);
            oActionCallingContext.GetParameter("Param2", ref value2);
// 返回string类型的值 其实方式还可以序列化转化obj为string 然后在另一端解析
            string value3 = (int.Parse(value1) + int.Parse(value2)).ToString();
            oActionCallingContext.AddParameter("ReturnParam", value3);

// 通过ContextParameterBlock 返回object 或者 list<obj>类型的值
            ContextParameterBlock block = new ContextParameterBlock();
   
            Book BookVlaue = new Book() { Name = "百年孤独", Price = "12" };
            block.Set("bookPara", BookVlaue);
           

            List<object> stringList = new List<object>() { "aa", "bb", "cc" };
            block.SetList(stringList);

            oActionCallingContext.SetContextParameter(block);
        }
       
    } 

 internal class ExecuteAction : IEplAction
    {
        public bool Execute(ActionCallingContext oActionCallingContext)
        {
            
            ActionManager manager = new ActionManager();
            Eplan.EplApi.ApplicationFramework.Action action = manager.FindAction("ActionParaAction");
            ActionCallingContext ctx = new ActionCallingContext();
            ctx.AddParameter("Param1", "1");
            ctx.AddParameter("Param2", "2");
            action.Execute(ctx);

            // 接收返回值
            string value3 = "";
            ctx.GetParameter("ReturnParam", ref value3);

            object obj = new object();
            ContextParameterBlock contextBlock = ctx.GetContextParameter();
            contextBlock.Get("objParam", ref obj);
            
            List<object> objList =  contextBlock.GetList();

            return true;
        }
    }

远程调用行为

远程调用需要注意eplan占用的地址和端口

 private void Button_Click(object sender, RoutedEventArgs e)
        {
        EplanRemoteClient m_pClient = new EplanRemoteClient();
     // 建立连接
         m_pClient.Connect("127.0.0.1", "49152");   //default port for EPLAN instance is 49155
// 调用
        bool oResp = m_pClient.ExecuteAction("ActionParaAction");
// 断开连接
        m_pClient.Disconnect();
    }
