C# 向pObject添加类时发生反射类型加载异常 我现在开发了一个C WWPF应用程序，它运行良好，直到我把VHDC++封装器类添加到我的项目，女巫是PRITTY大，所以我不张贴在这里，它本身工作良好。在我的项目中，当添加类文件并运行我的程序时，我在EntityFramework的这一行中得到一个错误 CDEnteties.Services.Add(service);

我收到一个错误{“无法从程序集'cloud opeaner，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null'加载类型'STORAGE\u DEPENDENCY\u INFO\u Union'，因为它包含偏移量为0的对象字段，该字段未正确对齐或与非对象字段重叠。”：“STORAGE\u DEPENDENCY\u INFO\u Union”}我不知道这两件事有什么关系，为什么会发生

编辑： 堆栈跟踪

看起来这与EF本身无关。您的程序集中似乎有一个无效的类型，EF只是接触它，因此它会爆炸。如果尝试手动加载此类型（例如，

Console.WriteLine（typeof（'STORAGE\u DEPENDENCY\u INFO\u Union'）.FullName）；

），即使项目中没有EF，也会看到相同的异常。如果不使用该类型，则需要修复或删除该类型（以及依赖该类型的代码）。

Show the stack trace.EF正在尝试加载与模型匹配的类型。其方法是从程序集中探测所有类型。尝试将类型放入单独的程序集中。顺便说一句，如果无法加载类型，你的包装器类在.NET项目中应该如何工作？我不确定你在问什么，我找到了一个小样本应用程序，可以在framework 4.5下编译，运行良好。当我将代码添加到我的应用程序时，我得到了错误，代码在这里我只是更改了名称空间和类名，我在问您是否能够使用导入的代码-尤其是GetStorageDependencyInformation方法？它们的类型对齐有问题（这样做是为了匹配本机结构/联合）。我相信'STORAGE\u DEPENDENCY\u INFO\u Union'类型有问题，但由于您没有使用它，CLR不会尝试加载它，您也看不到问题。要确认-在使用EF（或创建没有EF的测试应用程序）之前，请在应用程序中放入

Console.WriteLine（typeof（'STORAGE\u DEPENDENCY\u INFO\u Union'）。全名）您是否看到相同的异常？抱歉，等待，我在类
控制台.WriteLine（typeof（NativeMethods.STORAGE\u DEPENDENCY\u INFO\u Union.FullName）中添加了代码行然后调用它。获取异常{“无法从程序集'cloud opeaner take1，版本=1.0.0.0，区域性=neutral，PublicKeyToken=null'加载类型'STORAGE\u DEPENDENCY\u INFO\u Union'，因为它包含偏移量为0的对象字段，该字段未正确对齐或与非对象字段重叠。”：“STORAGE\u DEPENDENCY\u INFO\u Union”}。那么，这种结构是问题的根源吗？
