How to access a class Data outside another class

I have a property Data in a class BaseLVItem

namespace Spo.Plugins
{



public class BaseLVItem : System.Windows.Forms.ListViewItem
   {
      public virtual IBaseObject Data
      {
         get{ return m_data; }
      }
      private IBaseObject m_data = null;

we used it properly like shown below in a class ResourcePolicySystemsLVI

public class ResourcePolicySystemsLVI : BaseLVItem
    {


    public new IResourcePolicy Data
    {
        get
        {
            return (IResourcePolicy)base.Data;
        }
    }}

but when i used in the following class i am getting error 'System.ComponentModel.StringConverter' does not contain a definition for 'Data'

using Spo.Plugins;

   public class ResourcePolicyConverter : StringConverter
   {
       public new IResourcePolicy Data
       {
           get
           {
               return (IResourcePolicy)base.Data;
           }
       }

i am not able to implement BaseLVItem class here,Can any body guide me here

Dixon i am implementing like this

   public class ResourcePolicyConverter : StringConverter 
   {
      BaseLVItem lvItem = new BaseLVItem();
      IResourcePolicy data = (IResourcePolicy)lvItem.Data;
--------------------
else if ((value == null) && data.AgentVersion != null )  
            {
                return m_nullPolicy;
            }

It's because your class ResourcePolicyConverter is inheriting from StringConverter rather than BaseLVItem. A typo?

The reason you cannot use the Data property in your second example is that ResourcePolicyConverter doesn't inherit from BaseLVItem and thus, the Data property is not available in the base.

You can simply instantiate a new BaseLVItem and then access the Data property.

BaseLVItem lvItem = new BaseLVItem();
IResourcePolicy data = (IResourcePolicy)lvItem.Data;
