Win32 Types ---- CLR Type
Struct需要在C#里重新定义一个Struct
CallBack回调函数需要封装在一个委托里，delegate static extern int FunCallBack(string str);
unsigned char** ppImage替换成IntPtr ppImage
int& nWidth替换成ref int nWidth
int*, int&, 则都可用 ref int 对应
双针指类型参数，可以用 ref IntPtr
函数指针使用c++: typedef double (*fun_type1)(double); 对应 c#:public delegate double fun_type1(double);
char* 的操作c++: char*; 对应 c#:StringBuilder;
c#中使用指针:在需要使用指针的地方 加 unsafe
unsigned char对应public byte
typedef void (*CALLBACKFUN1W)(wchar_t*, void* pArg);
typedef void (*CALLBACKFUN1A)(char*, void* pArg);
bool BIOPRINT_SENSOR_API dllFun1(CALLBACKFUN1 pCallbackFun1, void* pArg);
调用方式为
[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate void CallbackFunc1([MarshalAs(UnmanagedType.LPWStr)] StringBuilder strName, IntPtr pArg);
