For python calls c#, here presents a new method, which ues cle developed by srplab..A function “Add” is defined in lua which returns the sum of two input integers. The function also calls python method “Show” to print the result.

There are three steps:

1.       Init cle, create service group, and create service.

2.       Define extends class of StarObjectClass, and defines a new function “Add” of it.

3.       Create interface object, named “TestClass”.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using star_csharp;

namespace AddFunctionService

{

//--Step2 : Define extends class of StarObjectClass, and defines a new function “Add” of it.

    class MyObjectClass : StarObjectClass

    {

        public int Add(StarObjectClass self, int x, int y)

        {

//--Callback to script function

            self._Call("Show", x + y);

            return x + y;

        }

        public MyObjectClass(StarObjectClass srcobj)

            : base(srcobj)

        {

        }

    }

    class Program

    {

        static void Main (string[] args)

        {

        //--Step1 : Init cle, create service group,import sharelibrary,  and create service

            StarCoreFactory starcore = StarCoreFactory.GetFactory();

            StarServiceClass Service = starcore._InitSimple("AddFunctionService", "123", 0, 0);

              //--Step3 : Create interface object, named “TestClass”.

            MyObjectClass Obj = new MyObjectClass(Service._New("TestClass"));

        }

    }

}

For python code calls the above c# file, there are three steps;

1.       Init cle, create service group,import c# file,  and create service.

2.       Create Instance of object “TestClass” defined in c#.

3.       Call function “Add”.

import starpy

--Step 1 : Init cle, create service group,import c# file,  and create service.

Service=starpy._InitSimple("test","123",0,0,"AddFunctionService.dll");

--Step 2: Create Instance of object “TestClass” defined in c#.

a = Service.TestClass._New();

--Step 3: call function “Add”

def a_Show(self, Para ) :

    print("print from python call back ", Para )

a.Show = a_Show; 

print("Add returns : ",a.Add(12,34))

Service._ServiceGroup._ClearService()

starpy._ModuleExit()

Run : starapp -e python_call.py?script=python, or

     python python_call.py
