xlua-C#代码访问lua的变量和函数

C#代码如何访问lua代码中数据呢？主要基本数据类型、table以及function函数等。

lua代码脚本如下

--Lua全局变量

--[[基本数据类型]]--
Num = 100;
Name = 'Hello';
IsOk = true;

--[[table表数据]]--

 example_table={
   id = 'W',
   age = 10,
   sex = 0,
   1,--多余变量1
   2,--多余变量2

   setSex = function(self,sexValue)
     sex = sexValue;
   end,

   getSex = function()
      return sex;
   end
 }


 example_table2={
    id = 102,
    num = 25,
    vip = 3
 }

 example_table3 = {
    1,
    2,
    3
 }


 --[[函数function]]--

 function Method1()
   print('=====lua method1=====');
 end

 function Method2(a,b)
    print('=====lua method2=====');
    c = a+b;
    a=a+2;
    b=3;    
    return c,a,b;
 end

 function Method3()
    print('=====lua method3=====');

    return Method1;
 end
