LuaCallCSharp 里面需要配置 Dictionary 的 Enumerator 和 KeyValuePair 么？

我把 xLua 里使用反射时的 Warning 打开了，且该成了报错，然后我在 LuaCallCSharp 里面配置了 Dictionary<int, int>，但是运行时会提示我：

我加了 Dictionary<int, int>.Enumerator 之后，第一个错还在，第二个变成了：

System.Collections.Generic.KeyValuePair`2[System.Int32,System.Int32] not gen, using reflection instead

我尝试再加上 KeyValuePair<int, int>，但是生成完代码后会有编译报错：

Assets\ThirdParty\XLua\Gen\System_Collections_Generic_KeyValuePair_2_System_Int32_System_Int32_Wrap.cs(132,39): error CS1061: 'KeyValuePair<int, int>' does not contain a definition for 'Deconstruct' and no accessible extension method 'Deconstruct' accepting a first argument of type 'KeyValuePair<int, int>' could be found (are you missing a using directive or an assembly reference?)

List我也有遇到了类似的问题，会说 System.Collections.Generic.List`1[T] 和对应的 Enumerator 没生成。

请问这类问题要怎么解决呢？

每一个不同泛型参数的泛型示例，都是不一样的类，如果要避免反射，就要加

你这个是别的参数，不是Dictionary<int, int>？

我已经加了 Dictionary<int, int>，但是还是有反射提示，而且很奇怪 提示的是 System.Collections.Generic.Dictionary`2[TKey,TValue] 而不是这种指出具体类型的：System.Collections.Generic.Dictionary`2[System.Int32,System.Int32]

我在 Lua 里面的调用是： for id, count in pairs(InventorySystem.items) do 这个 InventorySystem.items 就是那个 Dictionary
