介绍

之前基本都是从C#中的List或者Dictionary转成luaTable，很少会把LuaTable转成C#的List或者Dictionary，前几天正好做需求的时候要将lua里面的数据转成C#中的集合，C#List或者Dictionary转成luaTable的文章之前写过可以直接参考。

lua中创建表测试

lua中list表

注意luatable的数据是从1开始的 不是从0开始，这里默认的Key是1，2，3，4，5，6，7，8，9

	--lua中的表this.testList = {1,2,3,4,5,6,7,8,9}--C#中//获取lua表LuaTable table = LuaManager.lua.GetTable("UIMainCityCtrl.testList");//lua表的长度打印Debug.LogError("table.Length = " + table.Length);//转换成数组打印object[] tabArray = table.ToArray();for (int i = 0; i < tabArray.Length; i++){Debug.LogError("tabArray[" + i + "] = " + tabArray[i]);}//使用luaTable直接打印for (int i = 0; i < table.Length; i++){Debug.LogError("table[" + (i + 1).ToString() + "] = " + table[(i + 1)]);}//上面的这两种打印的结果都是一样的。如果使用的是

打印如下所示：

表转成List

这两个方法本质上其实是一样的，LuaArrayTable可以理解成是对object[]的一层封装
方法一

	object[] obj = table.ToArray();List<object> arr1 = new List<object>(obj);#region 打印一var iter = arr1.GetEnumerator();while (iter.MoveNext()){Debug.LogError("iter.Current = " + iter.Current);}#endregion#region 打印二arr1.ForEach((item) => {Debug.LogError("item = " + item);});#endregion

方法二
这里只是转换方法稍微变了一下，这里不多解释了，只是封装了一下

	    //LuaArrayTable luaArray = table.ToArrayTable(); 另一种转换方法LuaArrayTable luaArray = new LuaArrayTable(table);//LuaArrayTable的打印如下var iter = luaArray.GetEnumerator();while (iter.MoveNext()){ Debug.LogError("iter  = " + iter.Current);}List<object> arr2 = new List<object>(luaArray);//简化下来可以这样List<object> arr2 = luaArray.ToList();

注意一点LuaArrayTable其实就是对List的一层封装，所以Key只能是Int

表转成Dictionary

	//直接转成Object,object类型字典LuaDictTable<object, object> luaArray = table.ToDictTable<object, object>(); //Dictionary<object, object> dic = luaArray.ToDictionary(k => k.Key, v => v.Value);Dictionary<object, object> dic = luaArray.ToDictionary();//转成Int,Object类型的字典LuaDictTable<int, object> luaArray = table.ToDictTable<int, object>();//Dictionary<int, object> dic = luaArray.ToDictionary(k => k.Key, v => v.Value);Dictionary<int, object> dic = luaArray.ToDictionary();//转成int，int类型的字典LuaDictTable<int, int> luaArray = table.ToDictTable<int, int>(); //Dictionary<int, int> dic = luaArray.ToDictionary(k => k.Key, v => v.Value);Dictionary<int, int> dic = luaArray.ToDictionary();//转成int，string类型的字典LuaDictTable<int, string> luaArray = table.ToDictTable<int, string>(); //Dictionary<int, string> dic = luaArray.ToDictionary(k => k.Key, v => v.Value);Dictionary<int, string> dic = luaArray.ToDictionary();//打印代码var itor = dic.GetEnumerator();while (itor.MoveNext()){Debug.LogError("itor.Current.Key = " + itor.Current.Key + " ,itor.Current.Value = " + itor.Current.Value);}itor.Dispose();

打印如下

键值对表

键值对的这种表必然是无法转成list，既然是键值对只能转成字典Dictionary

	--lua中--table表现的dictionarythis.testDic = {["1"] = 50,["a"] = 80,["3"] = 120,["b"] = 130}//C#中//获取lua表的另一种获取方法//LuaTable table = LuaManager.lua.GetTable("UIMainCityCtrl.testDic");//lua表的长度打印Debug.LogError("table.Length = " + table.Length);LuaDictTable dic = table.ToDictTable();//同上面的这个转换一样//LuaDictTable<string, object> dic = table.ToDictTable<string,object>();//转成value为int的键值对字典//LuaDictTable<string, int> dic = table.ToDictTable<string, int>();var itor = dic.GetEnumerator();while (itor.MoveNext()){Debug.LogError("itor.Current.Key = " + itor.Current.Key + " ,itor.Current.Value = " + itor.Current.Value);}itor.Dispose();

打印如下所示：
这里有一点是键值对方式的LuaTable是没有长度的，长度为0

表转成Dictionary

转换成字典的方式

	//string,object类型字典LuaDictTable dic = table.ToDictTable();Dictionary<string, object> unitydic = dic.ToDictionary(k=>k.Key.ToString(),v => v.Value);//LuaDictTable<string, object> dic = table.ToDictTable<string, object>();//Dictionary<string, object> unitydic = dic.ToDictionary(); //string int类型字典LuaDictTable<string, int> dic = table.ToDictTable<string, int>();Dictionary<string, int> unitydic = dic.ToDictionary(); //打印如下var itor = unitydic.GetEnumerator();while (itor.MoveNext()){Debug.LogError("itor.Current.Key = " + itor.Current.Key + " ,itor.Current.Value = " + itor.Current.Value);}itor.Dispose();

多类型键值对表

表转成Dictionary

键值对的这种表必然是无法转成list，既然是键值对只能转成字典Dictionary

	--lua中--table表现的dictionarythis.testDic = {["1"] = 1,[true] = 1,[false] = true,["123"] = false,[5] = "heiheihei"}//C#中//获取lua表的另一种获取方法//LuaTable table = LuaManager.lua.GetTable("UIMainCityCtrl.testDic");LuaDictTable<object,object> dic = table.ToDictTable<object, object>();Dictionary<object, object> unitydic = dic.ToDictionary(); var itor = unitydic.GetEnumerator();while (itor.MoveNext()){Debug.LogError("itor.Current.Key = " + itor.Current.Key + " ,itor.Current.Value = " + itor.Current.Value);}itor.Dispose();

总结

lua中的LuaTable、LuaArrayTable、LuaDictTable<K,V>这几个其实可以跟Unity中List和Dictionary相互转换。
后面会说一下距离怎么在C#中增删改查LuaTable、LuaArrayTable、LuaDictTable中的数据
