basic c# question

Hi

I don't program in c# and i have to do something in this language in a bit of a rush.

How would i create an abstract superclass that had several properties and then 2 classes that inherit from this superclass (they must inherit all of the get/set methods). could you just show me a basic example. I am sure there are tonnes of examples of the internet but i just need a basic bare bones one to get me started so i thought i would ask here.

thanks a lot
andrea

// public abstract superclass that inherits from the Object class
public abstract class SuperClass: Object
{
   public abstract string Property1;
   public abstract int Property2;
   public abstract object Property3;
}


public class SubClass1: SuperClass
{
    public string Property1
    {
         get{//do stuff}
         set{//do stuff}
    }
    public int Property2
    {
         get{//do stuff}
         set{//do stuff}
    }
    public object Property3
    {
         get{//do stuff}
         set{//do stuff}
    }

shouldn't you declare the properties as virtual ?

ozymandias seems right but i suppose a MUSTINHERIT keyword should be added !!
as your sentense "(they must inherit all of the get/set methods)"... suggests

hay TOD dont you think your answer doesnt satisfy this condition?
"(they must inherit all of the get/set methods)"

superclass should be having get/set and they should be inherited by subclass?!!
please justify your answer !
