struct转IntPtr的方式和IntPtr转struct的方式

public IntPtr structToIntPtr(STMobileFaceInfo info)     {         int size = Marshal.SizeOf(info);         IntPtr intPtr = Marshal.AllocHGlobal(size);         Marshal.StructureToPtr(info, intPtr, true);         return intPtr;     }

public STMobileFaceInfo IntPtrToInt(IntPtr info)

{

STMobileFaceInfo sTHuman = (STMobileFaceInfo )Marshal.PtrToStructure(info, typeof(STMobileFaceInfo ));

}
