Its all about Scopes.

Your test boolean variable, in the way you coded it, is local to your own class. If you wanted to get the value of the variable there are a couple of ways to do it.

Either;

Retrieve the value of test from a public function in your Class.



Then in Form1



Or just declare the test boolean and make it public.



Then do almost the same as before

Yeah, just make it public.

Whenever making cross class calls you have to setup and invoke them or else you will get cross thread errors and it will cause you a lot of problems. For accessing a variable on another class I would setup a function in that class that returns the value of the variable that you want. Here's an example:

Form1.cs:
bool getMe;
private void Form1_Load(object sender, EventArgs e){
getMe = FALSE;
}
public bool getVariable1(){
return getMe;
}

Class1.cs:
Form1 caller;
bool begotten;
public Class Class1{
public void Class1(Form1 x){//to get the proper variable we have to give it the form we're //using

caller = x;
begotten = caller.getVariable1();
}
}


Theres some invoke code that should go into the Form1.cs code to check if the call needs an invoke and if so how to execute it, but I can't remember it right of the top of my head. Just look up cross thread referencing in C# or something along those lines.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Form1
{
    class Class1
    {
        bool test = true;

        public bool GetTest()
        {
            return test;
        }
    }
}


Then in Form1


using System;

using System.Windows.Forms;

namespace Form1

        public Form1()
        {
            InitializeComponent();
        }

        private void test()
        {
            if (Class1.GetTest() == false)
            {
                MessageBox.Show("Hi");
            }

I did all that and here is what i got:

You need to create and instance of the class.
