一、新建项目：luademo

安装包：<PackageReference Include="NLua" Version="1.7.3" />

using NLua;
using System;

namespace luademo
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Lua state = new Lua();
            for (int i = 0; i < 1000; i++)
            {
                state["x"] = i;
                var res = state.DoString("return 10 + x*(5 + 2)")[0];
                Console.WriteLine(res);
            }
        }
    }
}
