For lua 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 call lua 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 lua code calls the above c#, there are three steps;

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

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

3.       Call function “Add”.

require "libstarcore"

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

Service=libstarcore._InitSimple("test","123",0,0,"AddFunctionService.exe?script=csharp");

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

a = Service.TestClass:_New();

--Step 3: call function “Add”

function a:Show( Para )

    print("print from lua call back ".. Para )

end   

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

Service._ServiceGroup:_ClearService()

libstarcore._ModuleExit()
