xlua - c#中LuaTable的Cast和ForEach示例

测试代码

string luaStr = @"
    local obj = 
    {
        1, 
        ['a'] = 'A', 
        2, 
        ['b'] = 'B', 
        [3.1] = 3.5, 
    }
    return obj
";
var results = m_LuaEnv.DoString(luaStr);
var luaObj = (LuaTable)results[0];
using (luaObj)
{
    Debug.Log($"len: {luaObj.Length}"); //结果3
    TestX(luaObj);
}

 

Cast示例1

public static void Test1(LuaTable luaObj)
{
    Debug.Log("---------- Test1");
    Debug.Log($"len: {luaObj.Length}");

    Debug.Log("---------- 1");
    var dict1 = luaObj.Cast<Dictionary<string, string>>();
    Debug.Log($"keys cnt: {dict1.Count}"); //2
    foreach (var entry in dict1)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- 2");
    var dict2 = luaObj.Cast<Dictionary<string, object>>();
    Debug.Log($"keys cnt: {dict2.Count}"); //2
    foreach (var entry in dict2)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- 3");
    var dict6 = luaObj.Cast<Dictionary<object, string>>();
    Debug.Log($"keys cnt: {dict6.Count}"); //2
    foreach (var entry in dict6)
    {
        Debug.Log($"{entry}");
    }
}

 

Cast示例2

public static void Test2(LuaTable luaObj)
{
    Debug.Log("---------- Test2");

    Debug.Log("---------- int -> int");
    var dict1 = luaObj.Cast<Dictionary<int, int>>();
    Debug.Log($"keys cnt: {dict1.Count}");
    foreach (var entry in dict1)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- int -> float");
    var dict2 = luaObj.Cast<Dictionary<int, float>>();
    Debug.Log($"keys cnt: {dict2.Count}");
    foreach (var entry in dict2)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- int -> double");
    var dict3 = luaObj.Cast<Dictionary<int, double>>();
    Debug.Log($"keys cnt: {dict3.Count}");
    foreach (var entry in dict3)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- int -> obj");
    var dict4 = luaObj.Cast<Dictionary<int, object>>();
    Debug.Log($"keys cnt: {dict4.Count}");
    foreach (var entry in dict4)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- float -> float");
    var dict5 = luaObj.Cast<Dictionary<float, float>>();
    Debug.Log($"keys cnt: {dict5.Count}");
    foreach (var entry in dict5)
    {
        Debug.Log($"{entry}");

Cast示例3

public static void Test3(LuaTable luaObj)

    Debug.Log("---------- Test3");

    Debug.Log("---------- obj -> int");
    var dict1 = luaObj.Cast<Dictionary<object, int>>();
    Debug.Log($"keys cnt: {dict1.Count}");
    foreach (var entry in dict1)
    {
        Debug.Log($"{entry}");
    }

    Debug.Log("---------- obj -> obj");
    var dict2 = luaObj.Cast<Dictionary<object, object>>();
    Debug.Log($"keys cnt: {dict2.Count}");
    foreach (var entry in dict2)
    {
        Debug.Log($"{entry}");
    }
}

 

ForEach示例1

public static void Test5(LuaTable luaObj)
{
    Debug.Log("---------- Test5");

    Debug.Log("---------- 1");
    luaObj.ForEach<string, string>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- 2");
    luaObj.ForEach<string, object>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- 3");
    luaObj.ForEach<object, string>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });
}

 

ForEach示例2

public static void Test6(LuaTable luaObj)
{
    Debug.Log("---------- Test6");

    Debug.Log("---------- int -> int");
    luaObj.ForEach<int, int>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- int -> float");
    luaObj.ForEach<int, float>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- int -> double");
    luaObj.ForEach<int, double>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- int -> obj");
    luaObj.ForEach<int, object>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

    Debug.Log("---------- float -> float");
    luaObj.ForEach<float, float>((k, v) =>
    {
        Debug.Log($"{k}={v}");
    });

ForEach示例3

public static void Test7(LuaTable luaObj)
{
    Debug.Log("---------- Test7");

    Debug.Log("---------- obj -> int");
    luaObj.ForEach<object, int>((k, v) =>
