Question

I have a class:

  class Stock : Product
  {
  }

And in that class i have made a Equals method:

  public bool Equals(Product p)
  {
      return (p.Id == this.Id);
  }

But it’s not working. It tells me that Equals:

Warning 1 ‘WindowsFormsApplication1.Stock.Equals(WindowsFormsApplication1.Product)’ hides inherited member ‘WindowsFormsApplication1.Product.Equals(WindowsFormsApplication1.Product)’. Use the new keyword if hiding was intended.

C:\Users\tom\Desktop\uni\WindowsFormsApplication1\WindowsFormsApplication1\WindowsFormsApplication1\Stock.cs    36  21  WindowsFormsApplication1

Anyone know why this is?

Answer 1

You need to override Equals method, which is already used in Product Class.

public override bool Equals(Product p)
{
    return (p.Id == this.Id);
}

Or use new keyword. But I don’t think ‘new’ is what you want.
