How do I make an abstract-override to display the result in a label in windows form?

Question

This is what I have tried:

 public abstract double getTotalPrice();

and

 public override double getTotalPrice()
    {

        this.discounted_price = (item_price * item_quantity) - (item_price * item_quantity * item_discount / 100);
        return discounted_price;
        
    }

I tried to put it in a label like this:

 private void button1_Click(object sender, EventArgs e)
    {
        DiscountedItem di = new DiscountedItem(textBox1.Text, Convert.ToDouble(textBox2.Text), Convert.ToInt32(textBox3.Text), Convert.ToDouble(textBox4.Text));

        
        label10.Show(di.getTotalPrice().ToString());


    }

When I click the button, it should compute for the total price and then, display it in a label. I keep searching but, I can't find the exact solution to this.

Answer 1

Use

label10.Text = di.getTotalPrice().ToString();

instead of Show()
