C#调用C++动态库参数转换

C++
extern "C"__declspec(dllexport)
void GetImageData(char*strImageID,int i_nPhysicalX, float i_fMag, int o_nPhysicalWidth, 
int o_nPhysicalHeight, ushort* i_pBuffer, int* io_nBufferSize)

c#
[DllImport("xxxxx.dll",EntryPoint="GetImageData")]
public static unsafe extern void GetImageData(char*strImageID,int i_nPhysicalX, float i_fMag, int o_nPhysicalWidth, 
int o_nPhysicalHeight, ushort* i_pBuffer, int* io_nBufferSize)

c#中

char*strImageID = (char*)Marshal.StringToCoTaskMemAnsi(strImageID_ptr)
ushort[,] i_pBuffer_t=new double[10,10]
ushort* i_pBuffer =&i_pBuffer_t[0,0]
