复数数学表达式 c#

Question

I am new to c# and I want to make a pretty simple (in my opinion) program for my end of semester course. The algorithm in C looks like this. It calculates debit of a fluid with Venturi effect:

delta_p= p2-p1;
sectiune_rel=s1/s2;

numarator = 0.5*densitate*(pow(sectiune_rel, 2)-1);
raport = delta_p/numarator;
viteza1 = sqrt(raport);

debit = s1*viteza1;

I want to make a simple windows form with c#:

private void Butonrezultat_Click(object sender, EventArgs e)
    {
        double p1, p2, densitate1, s1, s2, sectiune_rel, debit;

        double.TryParse(presiunemare.Text, out p1);
        double.TryParse(presiunemica.Text, out p2);
        double.TryParse(densitate.Text, out densitate1);
        double.TryParse(sectiunemare.Text, out s1);
        double.TryParse(sectiunemica.Text, out s2);


         sectiune_rel = s1 / s2;
         debit = s1 * Math.Sqrt((p2 - p1) / ((0.5 * densitate1 * Math.Pow(sectiune_rel, 2) - 1)));


            rezultat.Text = debit.ToString("c"). Remove(0 , 1);
    }

Every time I debug it doesn't show anything to rezultat textbox. Do I miss something? I spend like two days on tutorials and I really couldn't find anything similar.

It seems your method Butonrezultat_Click is not attached with click event of your button. Do Following

1. Select your button Butonrezultat in Design Mode of your Form
2. Click on Events button on top of Properties Window.
3. Scroll the events of Butonrezultat Button and search for Click
4. Select Butonrezultat_Click method from the drop down for click event.
5. Run Your Code
