Global variables using windows forms

Question

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 Applicationand 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.
