xLua和C#交互

在xLua脚本内加载三方dll：xlua.load_assembly('aLuaTestDll')  --不用加.dll后缀

使用C#内部类：CS.xxx.xxx.xxx   CS前缀是固定的，后面命名空间和类名按c#调用约定拼写

        public xLuaForm()
        {
            InitializeComponent();
            _luaEnv = new LuaEnv();
            //_luaEnv.
        }
        public void Print(string msg)
        {
            MessageBox.Show(msg);
        }
        private LuaEnv _luaEnv;
        public static void StaticMethod(string msg)
        {
            MessageBox.Show(msg);
        }
        private void button1_Click(object sender, EventArgs e)
        {
            
            var script = $@"
    xlua.load_assembly('NLuaTestDll')
    CS.System.Windows.Forms.MessageBox.Show('hello001')
    local newForm = CS.System.Windows.Forms.Form()
    newForm:ShowDialog();
    newForm:Dispose();
    person = CS.NLuaTestDll.Person()
    person.Name = 'Winter'
    person.Age = 10
    CS.WindowsFormsApp1.xLuaForm.StaticMethod(person:ToString())    
    participant = {{""张三"", ""李四"", ""老王"", ""狗蛋"", ""铁剩""}}
    CS.WindowsFormsApp1.xLuaForm.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+b
    end
";
            _luaEnv.Global["form"] = this;
            _luaEnv.DoString(script);
            var p = _luaEnv.Global.Get<Person>("person");
            MessageBox.Show(p.ToString());
        }

namespace NLuaTestDll
{
    [LuaCallCSharp]
    public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public string ToString()
        {
            return $"{Name} -- {Age}";
        }
    }
}

                local doc = CS.System.Xml.XmlDocument();
                doc:Load("d:\\123.xml");
                local node = doc:SelectSingleNode("RootConfig/ConfigList");
                local subNodeCnt = node.ChildNodes.Count
                 CS.System.Windows.Forms.MessageBox.Show(tostring(subNodeCnt))
                for i = 1, subNodeCnt do
                    local subNode = node.ChildNodes[i]
                    CS.System.Windows.Forms.MessageBox.Show(subNode.Attributes:GetNamedItem('ConfiglName').InnerText);
                    local alarmSourceNode = subNode:SelectSingleNode('SubNode1')
                    CS.System.Windows.Forms.MessageBox.Show(alarmSourceNode.InnerText)

                end

xLua使用c#的XmlDocument类解析xml文件，使用node.Attributes["xxx"]失败，改为调用node.Attributes:GetNamedItem可以正常读取节点属性

        public void SetButtonClickMethod(Button button, string luaMethodName)
        {
            var method = _luaEnv.Global.Get<EventHandler>(luaMethodName);
            button.Click += method;
        } 

        public void DelButtonClickMethod(Button button, string luaMethodName)
        {
            var method = _luaEnv.Global.Get<EventHandler>(luaMethodName);
            button.Click -= method;
        }

 xLua内创建winform控件，进行事件订阅遇到麻烦，需要c#内写函数协助，如上定义一个SetButtonClickMethod，由xLua调用，传递Button对象实例，xLua函数名称，即可实现将xLua函数订阅Button Click事件。还不够灵活，暂可达到预期目标。

function button_click(sender, e)
    CS.System.Windows.Forms.MessageBox.Show('hello001')
    Close();
end

    local newForm = CS.System.Windows.Forms.Form()
    local button = CS.System.Windows.Forms.Button()
    button.Width = 100;
    button.Height = 50;
    button.Text = "OK";
    button.Parent = newForm;
    button.Location = CS.System.Drawing.Point(10, 10)
    --button.DialogResult= CS.System.Windows.Forms.DialogResult.OK;
    form:SetButtonClickMethod(button,"button_click")
    newForm:ShowDialog();
    form:DelButtonClickMethod(button,"button_click")
    newForm:Dispose();

调用当前项目托管库功能

    xlua.load_assembly('CommonLib')  --导入CommonLib.dll
    CS.xxxx.CommonLib.IoHelper.CopyDirectory("D:\\Dir1","D:\\Dir1Bak",true) --调用CommonLib dll中的函数做目录深拷贝
