C++中的带有指针数组的结构体在C#上怎么封装，并作为形参传给C++dll的函数

Question

#pragma pack(1)
struct SqJpegScliceSize
{
unsigned int scliceSize[64];

unsigned char *jpegDst[64];
};
extern "C" _declspec(dllexport) void SqGetSliceData(SqJpegScliceSize *jss)
这是C++函数和结构体
在C#上怎么写?

Answer 1

 public struct SqJpegScliceSize
 {
     public uint[] scliceSize;
     public IntPtr[] jpegDst;
}
[DllImport("xxxxx.dll",ExactSpelling =false,EntryPoint = "SqGetSliceData",CharSet = CharSet.Auto, CallingConvention = CallingConvention.Cdecl)] public static void SqGetSliceData(out SqJpegScliceSize jss);

//初始化结构体
SqJpegScliceSize jss=new SqJpegScliceSize();
jss.scliceSize=new uint[64];
jss.jpegDst=new IntPtr[64];

//调用函数
SqGetSliceData（out jss）;
