Question

Let’s say I have the following code:

protected void ReservationForm()
{
double x = 50;
double tva = 1.196;
double totalAmount = 0;

totalAmount = x * tva;

ltrl_showText = "Total Amount is " + totalAmount;
}

protected void btn_submit_Click(object sender, EventArgs e)
{
ltrl_previewText = "You ordered nameProduct at the price of " + totalAmount ;
}

How can I get the variable totalAmount from the function above?

I know that with Java I can do this with super() and I found that the equal property on C# is base but I don’t know how to use it. I tried to change the function to public instead of protected but I always get an error.

Thanks for your time.

EDIT: I use AJAX, that’s why the total Amounts are on both functions. The first one I need it because the total amount changes depending the user selection and then on click he sees the preview page.

Answer 1

Use a private field:

private double totalAmount;

protected void ReservationForm()
{
    double x = 50;
    double tva = 1.196;
    this.totalAmount = x * tva;
    ltrl_showText = "Total Amount is " + this.totalAmount;
}

protected void btn_submit_Click(object sender, EventArgs e)
{
    ltrl_previewText = "You ordered nameProduct at the price of " + this.totalAmount ;
}
