Перегрузка при добавлении границы в текстовое поле [CS0121]

Question

Я пытаюсь создать новый компонент. когда я пытаюсь нарисовать край вокруг этого компонента, возникает перегрузка нагрузки. Буду признателен, если вы поможете.

Код расширения FillBorderRentangle

Код BorderHelper:

        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.Winapi)]
        private static extern IntPtr GetFocus();
        public static void FillBorder(this Graphics g, Color color, int borderSize, BorderStyle style){
            var pan = new Panel();
            g = pan.CreateGraphics();
            g.FillBorderRectangle(new SolidBrush(color), pan.Size, pan.Location, 5);
            pan.BorderStyle = style;
            pan.Size = new Size(GetControl.Width + borderSize * 2, GetControl.Height + borderSize * 2);
            pan.Location = new Point(GetControl.Left - borderSize, GetControl.Top - borderSize);
            pan.BackColor = color;
            pan.Parent = GetControl.Parent;
            GetControl.Parent = pan;
            GetControl.Location = new Point(borderSize, borderSize);
            pan.Dispose();
        }
        private static Control GetControl{
            get {
                Control focusControl = null;
                IntPtr focusHandle = GetFocus();
                if(focusHandle != IntPtr.Zero)
                    focusControl = Control.FromHandle(focusHandle);
                return focusControl;
            }
        }

Вот коды для компонента

public class MinaXTextBox : Control, IControl{
 protected override void OnPaint(PaintEventArgs e){
            var g = e.Graphics;
             if(_textActive) 
                    g.FillBorder(Color.Red,5,BorderStyle.None);
   }
}

в результате:

Полученная ошибка:
