Need to Create Abstract Class for Items

I need to create a class for Items? I planned to create it using Abstract Class. So other classes like Stores, Purchase, BOM can use the Items. I need to create some methods in Abstact class like ItemName, ItemDesc, ItemMake, etc., So that I can use it in any 开发者_开发百科other classes, how to achieve this?

Take a look at this MSDN article explaining how to create abstract classes. And thereafter create derived classes from it.

You should look over at the MSDN for more detailed information, but here's a simple mock:

public abstract class BaseItem
{
    public int ItemId{get;set;}
    public string ItemName{get;set;}
    /* Add additional properties */

    public void PublichSharedMethod()
    {
        /* This method will be publicly available to all derived members and external activators */
    }

    protected void PortectedMethod()
    {
        /* This method will be available only to derived classes */
    }

    protected virtual ProtectedBaseImplementation()
    {
        /* This method will be available only to derived classes, and they can override its behavior */
    }

    public abstract void RequriesImplementation();
        /* This method is publicly available to all, but all derived classes must implement it */

}
