halcon的Hobject转HObject

非托管C++代码：

class CPLUSALOG_API_20211029 CCTest
 {
 public:
     CCTest();
     int* Get();
     ~CCTest();
 protected:
     Hobject* m_pRegion;
 }
   CCTest::CCTest()
 {
     m_pRegion = new Hobject();
     Halcon::gen_circle(m_pRegion, 10.0, 10, 10);
 }
 int* CCTest::Get()
 {
     return (int*)m_pRegion->Id();
 }CCTest::~CCTest()
 {
     delete m_pRegion;
 }
 C#代码：
  public class CTest
     {
        public CTest(System.IntPtr ptr)
         {
             m_region = new HObject(ptr);
             HTuple tArea, tRow, tCol;
             HOperatorSet.AreaCenter(m_region, out tArea, out tRow, out tCol);
         }
         HObject m_region;
     }

调用方，托管C++代码：
     CCTest ctest;
             ProjectBaseLib::NGClass::CTest^ test = gcnew ProjectBaseLib::NGClass::CTest((System::IntPtr)ctest.Get());
