error C2814: “Drivers::CreateDriver::STRUCT_D2C_IN”: 本机类型不能嵌套在托管类型“

[神一样的对友]

这个在我机子上没有错误。

[ljhhh0123]

很明显，楼主用的是vs托管代码。不是纯c++.

[Cristinays]

我是用vc++建了一个类库，然后vc++自动生成了一个public class ref CreateDriver(生成的头文件Drivers.h)，我把ref去掉就好了，请问这是什么问题呢？谢谢了

[zmshy2128]

ref class 是C++/CLI中的引用类类型，相应的还有个值类型value class。
二者都跟纯C++的类有区别的。

一个函数、一个类（如果类中有嵌套类，也必须一致）要么按照C++/CLI的语义编译，要么按照纯C++的语义编译。

[day_learn]

在windows平台下，数组或纯结构使用ZeroMemory是安全的，而类(class)就使用构造函数进行初始化，不要调用ZeroMemory。 　
ZeroMemory是windows中的宏函数，楼主不要在构造函数中调用！　
另外，如果一个类的结构中包含STL模板（Vector、List、Map等等），那么使用ZeroMemory对这个类的对象中进行清零操作也会引起一系列的崩溃问题（指针指向内存错误、迭代器越界访问等）。

谢谢各位高手的回复，能否请各位高手帮个忙，帮我把下面的代码生成一下，把生成好的dll文件发给我，老板临时分配的又要得急，诚请各位帮忙，我的邮箱是[e-mail],在此谢谢了。
