Global variables using windows forms

Drew Taylor

I am creating a game using windows forms, i need to show the score on all windows. how do i create a global variable so that it can be displayed on every form?

How do i convert a string to an int? I know how to do it for the console but it doesn't seem to work when using windows forms.

Also, if and swtich statements don't seem to work when i use them in windows forms.

I still can't get the score to work,

I have a class that has the following code: This is the class I want the forms to refer to for the global variable and other methds.using System;

public class Information : Form1

{

string item = "Map";

public string items(string item)

{

this.labelItemText.Text = item;

return item;

}

And for example, in a form I want the score to be displayed in a label when the form is started, so I have done this:

Is this the right way? It says somthing about an overload is needed?

private void labelItemText_Click(object sender, System.EventArgs e)

{

this.labelItemText.Text = Information.items();

}

Thanks, that is helpful. I don't understand why I need a switch statement, where would the switch statement go in a form that has buttons etc, would it go after the class declaration?

Hi Drew, for declaring a global variable:You can add a static variable in a class file for the Application,and refer to the variable in each form. ex: declaration of static variable in a class file ---------------------------------------------- public class Class1 { public static int score; } you can access the variable within the form as Class1.score suppose u want to increase the score Class1.score=Class1.score+100 hope u got it Convert string to int:Convert.ToInt32(string) Switch case with C#forms -------------------- switch(n) { case 1: cost += 25; break; case 2: cost += 25; goto case 1; case 3: cost += 50; goto case 1; default: Console.WriteLine("Invalid selection. Please select 1, 2, or 3."); break; } i think this will help u.
