NLua和C#交互

 在Lua脚本内引入C# dll：luanet.load_assembly('NLuaTestDll')

在Lua脚本内引入C# 定义的类：TestClass=luanet.import_type('NLuaTestDll.TestClass')

将C#对象导入到Lua脚本：_luaEnv["xxx"] = xxx

将C#中定义的方法导入Lua脚本：

            var method = typeof(xLuaForm).GetMethod("StaticMethod");
_luaEnv.RegisterFunction("StaticMethod", null, method);

执行脚本后获取Lua内变量：_luaEnv["xxx"]

        public void Print(string msg){MessageBox.Show(msg);}private Lua _luaEnv;public xLuaForm(){InitializeComponent();_luaEnv = new Lua();_luaEnv.LoadCLRPackage();//_luaEnv.RegisterLuaClassType(typeof(Person), typeof(Person));}public static void StaticMethod(string msg){MessageBox.Show(msg);}private void simpleButton1_Click(object sender, EventArgs e){//_luaEnv.DoString("require 'CSharpCallLua'");var script = $@"luanet.load_assembly('NLuaTestDll')TestClass=luanet.import_type('NLuaTestDll.TestClass')Person=luanet.import_type('NLuaTestDll.Person')import(""System.Windows.Forms"")MessageBox.Show('hello001')local newForm = Form()newForm:ShowDialog();newForm:Dispose();person = Person()person.Name = 'Winter'person.Age = 10StaticMethod(person:ToString())participant = {{""张三"", ""李四"", ""老王"", ""狗蛋"", ""铁剩""}}StaticMethod('abc')--require 'CSharpCallLua'--person = {{Name = 'Tom', Age = 10}}name = 'jerry'form.Text = 'lua test'form:Print('hello  ' .. #participant)function add(a, b)return a+bend
";_luaEnv["form"] = this;var method = typeof(xLuaForm).GetMethod("StaticMethod");_luaEnv.RegisterFunction("StaticMethod", null, method);_luaEnv.DoString(script);var person = _luaEnv["person"] as Person;MessageBox.Show(person.Name);var addFun = _luaEnv.GetFunction("add");var resObj = addFun.Call(10, 20);}
