在Unity中使用ulua框架進行熱更新時，有的時候需要在不更新整包的情況下增加一些小功能，而這期間會用到一些沒有wrap到的Mono屬性或者方法，此時可以用過呼叫tolua的反射獲取。

C#程式碼：

using UnityEngine;
namespace Test
{
    public class ReflectionTest
    {
        // 屬性
        public string pubfield = "pubfield";

        private string prifield = "prifield";
        public string Prifield
        {
            get
            {
                return prifield;
            }
            set
            {
                prifield = value;
            }
        }

        // 方法
        public string getVector3ListDesc(Vector3[] v)
        {
            string desc = string.Empty;
            for (int i = 0; i < v.Length; i++)
            {
                desc += "(" + v[i].x + "," + v[i].y + "," + v[i].z + ")";
            }
            return desc;
        }

        // 靜態屬性
        public static string stapubfield = "stapubfield";

        private static string staprifield = "staprifield";
        public static string Staprifield
        {
            get
            {
                return staprifield;
            }
            set
            {
                staprifield = value;
            }
        }

        // 靜態方法
        public static string contactParam(string v1, int v2)
        {
            return v1 + v2.ToString();
        }
    }
}

function luaReflectionTest()
    --程式集反射
    require 'tolua.reflection'
    tolua.loadassembly('Assembly-CSharp')

    local reflectionTest = typeof("Test.ReflectionTest")
    local instance = tolua.createinstance(reflectionTest)

    --獲取和修改pubfield的值
    local pubfield = tolua.getfield(reflectionTest, "pubfield")
    local pubfieldValue = pubfield:Get(instance)
    print("pubfieldVale=" .. pubfieldValue)
    pubfield:Set(instance, "changedpubfield")
    local pubfieldValueChanged = pubfield:Get(instance)
    print("pubfieldValueChanged=" .. pubfieldValueChanged)
    pubfield:Destroy()

    --執行屬性的get 和 set 方法
    local prifield = tolua.getproperty(reflectionTest, "Prifield")
    local prifieldValue = prifield:Get(instance, nil)
    print("prifieldValue=" .. prifieldValue)
    prifield:Set(instance, "prifieldChanged", nil)
    local prifieldValueChanged = prifield:Get(instance, nil)
    print("prifieldValueChanged=" .. prifieldValueChanged)
    prifield:Destroy()

    --執行public 方法
    local getVector3ListDestFun = tolua.getmethod(reflectionTest, "getVector3ListDesc", typeof(Vector3):MakeArrayType())
    local params = {Vector3.New(1, 2, 3), Vector3.New(100, 101, 102), Vector3.New(201, 202, 203)}
    local paramsArr = tolua.toarray(params, typeof(Vector3))
    local funResult = getVector3ListDestFun:Call(instance, paramsArr)
    print("funReturnResult=" .. funResult)
    getVector3ListDestFun:Destroy()

    --獲取和修改靜態屬性stapubfield的值
    local stapubfield = tolua.getfield(reflectionTest, "stapubfield")
    local stacpubfieldValue = stapubfield:Get(nil)
    print("stapubfieldValue=" .. stacpubfieldValue)
    stapubfield:Set(nil, "stapubfieldChanged")
    local stapubfieldValueChanged = stapubfield:Get(nil)
    print("stapubfieldValueChanged=" .. stapubfieldValueChanged)
    stapubfield:Destroy()

    --執行靜態屬性的get 和 set 方法
    local staprifield = tolua.getproperty(reflectionTest, "Staprifield")
    local staprifieldValue = staprifield:Get(nil, nil)
    print("staprifieldValue=" .. staprifieldValue)
    staprifield:Set(null, "staprifieldChanged", nil)
    local staprifieldValueChanged = staprifield:Get(nil, nil)
    print("staprifieldValueChanged=" .. staprifieldValueChanged)
    staprifield:Destroy()

    --執行public static方法
    local contaceParamFun = tolua.getmethod(reflectionTest, "contactParam", typeof("System.String"), typeof("System.Int32"))
    local funResult1 = contaceParamFun:Call("傳入的值為：", 100)
    print("contaceParamFunResult=" .. funResult1)
    contaceParamFun:Destroy()
end
 

執行結果：
