close all open forms that formBorderStyle is None

for (var i = Application.OpenForms.Count - 1; i >= 0;i-- )
{
    var f = Application.OpenForms[i];
    if (f.Name != "frmMain" && f.FormBorderStyle == System.Windows.Forms.FormBorderStyle.None)
    {
        f.Close();
        //break;
    }
}

Use only what you need, Reduce global warming

Thank you!

I just remove the f.Name != "frmMain" . because in each time the value of f.Name was the same and equals "frmMain". I dont know why?!

for (var i = Application.OpenForms.Count - 1; i >= 0; i--)
            {
                var f = Application.OpenForms[i];
                if (f.FormBorderStyle == System.Windows.Forms.FormBorderStyle.None)
                {
                    f.Close();                    
                }
            }
