C# how do I make a procedure that is run every time a form is loaded?

Question

In my c# forms project I want this method to run every time I load any of my forms.

        foreach (Form frm in Application.OpenForms)
        {
            frm.WindowState = FormWindowState.Normal;
            frm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            frm.Bounds = Screen.PrimaryScreen.Bounds;
        }

Why `foreach` cannot be used in classes and why `WindowState` doesn't exist? I am confused by this. — mrogal.ski, Jan 31 '17 at 13:53
You write these code in some method of a class. not directly in class — Abdul Rehman Sayed, Jan 31 '17 at 13:57
Please post your full code not an extract, specially when the code you posted is not the problem — Camilo Terevinto, Jan 31 '17 at 13:58
I don't know what more you want honestly. The problem is that i already have this part of code on a button press but it only works for the form its in and isn't permanent. — Tom1, Jan 31 '17 at 14:03
I want it to be applied to every form by making this section a method that can be called in the form load of each one but only if the button has been pressed in a previous form to make a condition true. e.g. Button1_toggle() FullscreenMode = true — Tom1, Jan 31 '17 at 14:04
You cannot write code in a **class**, you need to create a **method** within that **class** to write code there — Camilo Terevinto, Jan 31 '17 at 14:05

My proposition: Create a BaseClass

public class BaseClass: Form

... and add method to it:

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    foreach (Form frm in Application.OpenForms)
    {
        frm.WindowState = FormWindowState.Normal;
        frm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        frm.Bounds = Screen.PrimaryScreen.Bounds;
    }
}

Add this exact base class to each of your forms, like such:

public partial class Form1 : BaseClass

Please at least format your code properly – Camilo Terevinto Jan 31 '17 at 14:05
yes I understand how to make it load for each form but how would I make this only work if a previous condition is true – Tom1 Jan 31 '17 at 14:06
Oh I see now. But here in this method you can use if(WindowState == FormWindowState.Maximized) – Paweł Swajdo Jan 31 '17 at 14:10
and if you really need to know if the button was pressed (windowState is not important, only the fact of clicking button) then I think you need to set some kind of global variable that informs you button was clicked. But this is rather strange solution. – Paweł Swajdo Jan 31 '17 at 14:15
yeah thats what i want to do but i also want to avoid global variables. I think the reason people didnt understand me was because i barely understood my own problem :/ – Tom1 Jan 31 '17 at 14:18
