POObject Oriented Approach for C#

Body
copied!<p>I am exploring this and see if this one make sense. For instance I have 2 abstract objects called: Customer and Tender. The relationship is that one Customer can have many Tenders. </p> <p>How can I achieve the following on the TestClient app:</p> <ol> <li><p><code>customer.InTender[0].ID = ???</code></p> <p>What method to handle to handle this? Do I need to pass <code>CustomerID</code> into <code>Customer</code> constructor to achieve this or ... ?</p></li> <li><p>If I want to get all tenders for that particular customer should I do this:</p> <pre><code>customer.InTender.Get() </code></pre></li> <li><p>How do I differentiate between All Tender VS All Customer Tender (point 3). I guess it will be like this. One with ID of Customer and the other one without?</p> <pre><code>inTender.Get() </code></pre></li> </ol> <hr> <pre><code>public abstract class Customer { protected Int64 id; protected string name; protected ArrayList tender; public abstract ArrayList Tender { get; set; } public abstract Int64 ID { get; set; } public abstract string Name { get; set; } public abstract bool Update(); public abstract bool Add(); public abstract bool Delete(); } public class CorporateCustomer : Customer { public CorporateCustomer () {} public override ArrayList Tender { get { return tender } set { tender = value; } } public override Int64 ID { get { return id; } set { id = value; } } public override string Name { get { return name; } set { name = value; } } public override bool Update() { return true; } public override bool Add() { return true; } public override bool Delete() { return true; } } public abstract class Tender { protected Int64 id; protected string name; public abstract bool Update(); public abstract bool Add(); public abstract bool Delete(); } public class InTender : Tender { public InTender () {} public override Int64 ID { get { return id; } set { id = value; } } public override string Name { get { return name; } set { name = value; } } public override bool Update() { return true; } public override bool Add() { return true; } public override bool Delete() { return true; } } </code></pre>
