title: How to access the Form Tools from Other Classes
body: <p>I'm new to programming and theres something i cant do and cant find from the internet about the problem i have.</p>
  
  <p>I'm making a basic Rullet game for practice.</p>
  
  <p>I want to make the Calculations in a separate Class for the sake of "Clean Coding".</p>
  
  <p>But i cant manage to control things like radioButton, CheckBox, TextBox from the Calculation Class i made.</p>
  
  <p>How can i access them?</p>
  
  <p>For example i want to check if the Rulet number if Even or Odd from another class.</p>
  
  <pre><code>// form.cs
  
  public static int ruletNumber;
  
  private void btnPlay_Click(object sender, EventArgs e)
  {
      Random rnd = new Random ();
      ruletNumber = rnd.Next(0,37);
      Calculation.Calc();
  
  }
  
  
  
  //Calculation.cs
  class Calculation
  {
          public static void Calc()
          {
              // this is where i must see if the radioButton is Checked or Not, but it dosent see it from this Class...
              if (ruletNumber / 2 == 0 &amp;&amp; rdbEven.Checked == true)
              {
                  //some code...
              }
          }
  
  }
  </code></pre>
