C #/vB how to define abstract attributes

The abstract attribute declaration does not provide the Implementation of the attribute accessors. It only declares that the class supports attributes, and leaves the accessors implementation to the derived class.
The following example shows how to implement abstract attributes inherited from the base class.

C #

Public abstract class base
{

    // name is a abstract property 
public abstract string Name
    {
get;
set;
    }  

}

public class Child: Base
{
private string m_Name;

 //override abstract property
public override double Name
    {
get
        {           
return m_Name;
        }
set
        {
           m_Name = value; 
         }
    }
}

VB.Net

Public MustInherit Class Base

// name is a abstract property 
Public MustOverride Name() As String   

End Class

Public class Child
      Inherits  Base

Private m_Name As String    
 //override abstract property
public Overrides Property Name() As String    
Get                   
Return m_Name;
End Get
Set        
           m_Name = value; 
    End Set
    End Property 

End Class

When declaring abstract attributes (such as name in this example), specify which attributes are available for accessors and do not implement them.
