[Resolved] Overriding...

Let's say I want to inherit Hashtable, and restrict it to allow only strings. I have this...

Code:

---

        public class Class1:Hashtable
        {
                public Class1() {}

                public override void Add(string key, string value)
                {
                }
 
        }

---

Which works great in VB (when converted to VB syntax, that is) but in C# I get "no suitable method found to override".

What am I missing?

Apparently, it won't let you override the Add() because the signature of the baseclasses Add() takes 2 objects and the method you are trying to use to override it takes 2 strings.

The code below worked for me, but not when the 2 parameters in the Add method were strings.

Code:

---

using System;
using System.Collections;

public class myClass : Hashtable
{
        public override void Add(object key, object value)
        {
                Console.WriteLine("Key is {0}, value is {1}", key, value);
        }
}

class newClass
{
        public static void Main()
        {
                myClass y = new myClass();
                y.Add("test", "test2");
        }
}

Well, the basic goal here is to make a type safe collection. So how would I go about only allowing certain object types, string in this case to be added? And why does this work in VB.NET and not C#?

This may help you.
