how do i get index of an object in a custom class?

I'm trying to an indexof method for a class that represents a list of objects.I would like to know the best approach. below is the code that I've come up with.

public int IndexOf(Product product)
    {

            Product p;
            for (int i = 0; i < products.Count; i++)
            {
                p = products[i];

                if (p == product)
                    return i;
            }
        return -1;
    }

I couldn't get .IndexOf() working for my problem, but I found the following solution worked a treat.

If products is of type List<Product> you can just use the IndexOf() method of your collection:

public int IndexOf(Product product)
{
   return products.IndexOf(product);
}
