我使用的是使用C＃x86应用程序在C ++ Win32中开发的第三方库。
我对这个库进行不同的调用，除了一个之外都会成功。
该通话包含复杂的签名。 这是C ++签名：
ER_CODE KMAPI CLGetMeasData(DEVICE_HANDLE hDevice, CL_COLORSPACE Type, CL_MEASDATA* pColor);
以下是了解签名

当我运行程序时，我遇到以下异常： （抱歉是法语）
不可能充电器类型'CL_MEASDATA'àpartirde l'assembly 'xxx，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null'，car il contient un champobjetàl'offding'0'quin'est pas correctement alignéouquiestchevauchéparun champ non objet。
用英语说：
无法加载“CL_MEASDATA”，因为它包含索引0处的字段 未对齐或非对象字段（近似翻译） 我;））
我发现产生问题的两个fiels包含一个嵌入了float列表的结构的字段（public float [] Data;）
如果我从联盟中删除它们似乎通过了但是我得到了堆栈不平衡异常（我认为这是第二个问题）。
但我需要他们！我已尝试使用“UnmanagedType”枚举或 ArraySubType属性，但没有结果确定。
我很高兴用大量代码发帖，但我删除了所有不必要的代码。
如果您有任何想法？
