I want to add more property for every shape
So I tried to create a cusom class that inherited from Nshape
but I failed because the Nshape has no new construction and is created by factory
How could I implement this functionality

Hi,

Here's a sample implementation of a class you can use as a Tag property for your shapes:

 

[Serializable]

public class NShapeExt : ICloneable

{

      public NShapeExt()

      {

            m_bMyProperty1 = true;

            m_sMyProperty2 = String.Empty;

      }

 

      public bool MyProperty1

      {

            get

            {

                  return m_bMyProperty1;

            }

            set

            {

                  m_bMyProperty1 = value;

            }

      }

      public string MyProperty2

      {

            get

            {

                  return m_sMyProperty2;

            }

            set

            {

                  m_sMyProperty2 = value;

            }

      }

 

      public object Clone()

      {

            NShapeExt shapeExt = new NShapeExt();

            shapeExt.m_bMyProperty1 = m_bMyProperty1;

            shapeExt.m_sMyProperty2 = m_sMyProperty2;

            return shapeExt;

      }

 

      private bool m_bMyProperty1;

      private string m_sMyProperty2;

}
