如何在C＃中使一侧圆形按钮？

如何解决如何在C＃中使一侧圆形按钮？

我找到了代码：

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,180,90);

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

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

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

有人可以解释一下我应该如何更改按钮，使按钮只有一侧圆角吗？

解决方法

经过研究，我设法为将来的用户制作了它。 这是仅将右下角四舍五入的代码：

 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();

        GraphPath.AddLine(Rect.X + w2,Rect.Y + w2,Rect.X,Rect.Y);
        GraphPath.AddLine(Rect.X + Rect.Width,Rect.Y,Rect.X + Rect.Width - w2,Rect.Y);
        GraphPath.AddArc(Rect.X + Rect.Width - w2 - radius,Rect.Y + Rect.Height - w2 - radius,radius,90);
        GraphPath.AddLine(Rect.X + w2,Rect.Y - w2 + Rect.Height,Rect.X - w2,radius);

        GraphPath.AddLine(Rect.X + w2,Rect.Y + Rect.Height + r2 + w2 + Rect.Y,Rect.X + w2,Rect.Y + Rect.Y);

        return GraphPath;

左上方

GraphPath.AddLine(Rect.X + w2,Rect.Y);
GraphPath.AddArc(Rect.X + Rect.Width - radius - w2,270,90);
GraphPath.AddLine(Rect.X + Rect.Width-w2,Rect.Y + Rect.Height,Rect.X+Rect.Width,Rect.Y+Rect.Height-w2);
GraphPath.AddLine(Rect.X + w2,radius);
GraphPath.AddLine(Rect.X + w2,Rect.Y + Rect.Y);  
return GraphPath;

右上方

GraphPath.AddArc(Rect.X + w2,180,90);
GraphPath.AddLine(Rect.X + Rect.Width,Rect.Y);
GraphPath.AddLine(Rect.X + Rect.Width - w2,Rect.X + Rect.Width,Rect.Y + Rect.Height - w2);
GraphPath.AddLine(Rect.X + w2,Rect.Y + Rect.Height - r2 - w2,Rect.Y + r2 + w2);
return GraphPath;
