（在Unity 5.6 beta版上解决）从5.3.x升级后构建的Unity 5.5x外部dll问题

大家好，谢谢你们抽出时间。 我在Unity 5.5.0f3上构建（win x86）一个特定项目时面临一个问题

去年，我使用Unity5.2.x为一个与视障人士相关的项目编写了一些代码。当时我发现了一个非常有趣的由达古二世所做的整合 他使用外部DLL Interop.SpeechLib.DLL创建了一个可以与windows SAPI 5.x交互的unity项目

所以我采纳了他的想法，制作了关于如何与windows SAPI交互的更好的示例代码，并分享了代码和构建（由Unity 5.2.x制作）

现在，Unity 5.4.0发布后，代码保持运行，因此试图构建Unity的dll突然停止，出现以下错误：

*ReflectionTypeLoadException: The classes in the module cannot be loaded
System.Reflection.Assembly.GetTypes () (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/Assembly.cs:371)

UnityEditor.HostView:OnGUI()*

这个问题与sapi dll有关，我一直等到unity 5.5发布，但它仍然不起作用，我还没有足够的经验来解决这个问题

谢谢你的建议

事实上，我在Win8虚拟机上运行的Unity 5.6.0b5测试版刚刚成功地构建了脚本，因此我很有信心，也可以在Unity 5.6最终版本中构建此脚本。我也一直在研究这个问题。它声明dll中的所有引用都需要存在。dll Interop.speech引用了mscorlib v2.0.0.0，但unity提供了mscorlib v4.0.0.0。我想知道我们是否供应v2，它是否会起作用。但现在没有时间测试它。很抱歉
