Question

Basically I would like the user to input 3 values into a textbox and have a button that calculates the total of the 3 inputted values. I thought I could read the user input and then convert it into an integer and from that apply a formula to work out fnum+snum+tnum = total; What I have done so far does not work can anybody guide me thanks.

         int num1 = int.Parse(weighting1.Text);
         int num2 = int.Parse(weighting2.Text);
         int num3 = int.Parse(weighting3.Text);
         total = num1+num2+num3;
         int total = int.parse(lTotal.Text);
         // Code to display the variable

Answer 1

instead of int.parse(lTotal.Text) you need to assign total’s string value to label

lTotal.Text = total.ToSTring();

Your code should be:

 int num1 = int.Parse(weighting1.Text);
 int num2 = int.Parse(weighting2.Text);
 int num3 = int.Parse(weighting3.Text);
 int total = num1+num2+num3;
 lTotal.Text = total.ToSTring();
