Question

I’m getting two errors, I see where they are, I just don’t know how to change the code to fit my needs.

Here’s the code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace zaidimas
{
    public partial class Form1 : Form
    {

        public int z1 = 1;
        public int z2 = 1;
        public int kauliukas;
        public string nuoroda;

        public Form1()
        {
            InitializeComponent();
            button2.Visible = false;
            button1.Visible = true;
            webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
            webBrowser1.Navigate("siauliaicity.99k.org/zaidimas/");
        }

        private void button1_Click(object sender, EventArgs e)
        {

            // Gaunama kauliuko reikšmė
                int kauliukas = RandomNumber(1, 6);
                pictureBox1.ImageLocation = kauliukas + ".jpg";
                label2.Text = "Kauliukas ridenos ridinėjosi ir sustojo ties" + kauliukas + "taškais";


                int z1 = z1 + kauliukas; (first error goes here)
                string nuoroda = "http://siauliaicity.99k.org/zaidimas/index.php?z=1&z1=" + z1 + "&z2=" + z2 + "&plus=" + kauliukas;
                webBrowser1.Navigate(nuoroda);
                button1.Visible = false;
                button2.Visible = true;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            // Gaunama kauliuko reikšmė
            int kauliukas = RandomNumber(1, 6);
            pictureBox1.ImageLocation = kauliukas + ".jpg";
            label2.Text = "Kauliukas ridenos ridinėjosi ir sustojo ties" + kauliukas + "taškais";

            int z2 = z2 + kauliukas; (second error goes here)
            string nuoroda = "siauliaicity.99k.org/zaidimas/index.php?z=2&z1=" + z1 + "&z2=" + z2 + "&plus=" + kauliukas;
            webBrowser1.Navigate(nuoroda);
            button1.Text = "Ridenti kauliuką! (Ridena: Pirmasis žaidėjas)";

            button2.Visible = false;
            button1.Visible = true;
        }

        // Kauliuko funkcija
        private int RandomNumber(int min, int max)
        {
            Random random = new Random();
            return random.Next(min, max);
        }

        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {

        }
    }
}

Error message’s:

Error 1 Use of unassigned local variable ‘z1’ C:\Users\Tutis\Documents\Visual Studio 2008\Projects\zaidimas\zaidimas\Form1.cs 38 26 zaidimas

and

Error 2 Use of unassigned local variable ‘z2’ C:\Users\Tutis\Documents\Visual Studio 2008\Projects\zaidimas\zaidimas\Form1.cs 52 22 zaidimas

Any suggestions how to change the code?

Answer 1

You have already declared variable with names z1 and z2 you cannot declare them again

I think you wanted to use the same variable but you have accidently put int in start

change

int z1 = z1 + kauliukas; (first error goes here)

to

z1 = z1 + kauliukas; (first error goes here)

and

 int z2 = z2 + kauliukas; (second error goes here)

to

 z2 = z2 + kauliukas; (second error goes here)
