C# windows App one specific rounded corner

Question

Can someone please help me to make a class which creates a button with one specific corner rounded?

    GraphicsPath GetRoundPath(RectangleF Rect, int radius, float width=0)
    {

        //Fix radius to rect size
        radius = (int) Math.Max(( Math.Min(radius, Math.Min(Rect.Width, Rect.Height)) - width),1);

        float r2 = radius / 2f;
        float w2 = width / 2f;            
        GraphicsPath GraphPath = new GraphicsPath();

        //Top-Left Arc
        GraphPath.AddArc(Rect.X + w2, Rect.Y + w2, radius, radius, 180, 90);

        //Top-Right Arc
        GraphPath.AddArc(Rect.X + Rect.Width - radius - w2, Rect.Y + w2, radius, radius, 270, 90);

        //Bottom-Right Arc
        GraphPath.AddArc(Rect.X + Rect.Width - w2 - radius,
                           Rect.Y + Rect.Height - w2 - radius, radius, radius, 0, 90);
        //Bottom-Left Arc
        GraphPath.AddArc(Rect.X + w2, Rect.Y - w2 + Rect.Height - radius, radius, radius, 90, 90);

        //Close line ( Left)           
        GraphPath.AddLine(Rect.X + w2, Rect.Y + Rect.Height - r2 - w2, Rect.X + w2,Rect.Y + r2 + w2);
                   
            
        
        return GraphPath;
    }

Please show your attempt / code for this question. Thank you :) — Smithy, Aug 26 '20 at 11:07
