Question

private void btnMiles_Click(object sender, EventArgs e)
{
    try
    {
        int milesless200 = int.Parse(txtMiles.Text);
        int milesmore200 = int.Parse(txtMiles200.Text);

        MilesCal workingoutmilescost = new MilesCal();
        if (milesless200 > 200)
        {
            lblMilesMorethan200.Text = "You can't enter more then 200 in the first box";
        }
        else
        {
            if (milesmore200 == 0)
            {
                 int carry = workingoutmilescost.MilesRepay(milesless200);
                 lblMilesShow.Text = carry.ToString();

            }
            else
            {
                int carry = workingoutmilescost.MilesRepay(milesless200, milesmore200);
                lblMilesShow.Text = carry.ToString();
            }
        }
        lblMilesError.Text = "No Error";
    }
    catch (FormatException fEx)
    {
        lblMilesError.Text = fEx.Message;
    }
}

My Defined class of MilesCal

 class MilesCal
    {
        public int MilesRepay(int a)
        {
            int x;
            return x = (a*5)/100;
        }
        public int MilesRepay(int a, int b)
        {
            int y;
            return y = (a*5)/100 + (b*2)/100;
        }
    }

This code is suppose to display in a label the cost a driver gets back from their driving at 5p for the first 200 miles then 2p after that. I have got the code working but then discovered that it has to be done using Method overflow. at the minute am getting an error Error 1 Cannot convert method group ‘ToString’ to non-delegate type ‘string’. Did you intend to invoke the method? at

lblMilesShow.Text = carry.ToString;

Added the ().

Now the catch seems to be trippping, can i ask you guys again to work this out because its probably a simple fix again?

Answer 1

Try to add brackets

lblMilesShow.Text = carry.ToString();
