    {
    CheckBox1.Checked = false
    }
    else
    {
    CheckBox1.Checked = true
    }

I don't know if you're working in ASP.NET, WPF, WinForms, ...

But it's as easy as check if checkbox is checked, then uncheck, and viceversa.

Or you can implement an extension method like:

public static class CheckboxExtensions
{
     public static void ToggleChecked(this CheckBox some) 
     {
           if(some != null) 
           {
                  if(some.Checked)
                  {
                        some.Checked = false;
                  }
                  else
                  {
                        some.Checked = true;
                  }
           }
    }
}

... And your actual code will look like this:

chkSome.ToggleChecked();

Try

checkBox1.Checked = !checkBox1.Checked;
