Question

我正在尝试为Line类设置代码，除了我的方块和圆圈的DefaultLineThickness之外，还有它自己的厚度。尽管我想使用g.DrawLine（Pens.Black，25,40,126,126）;它需要在它自己的类中并继承我已经完成的其他形状。我发现这个话题最接近我的问题，但它在XAML和其他地方只是简单的g.DrawLine

尝试用圆形，正方形和直线制作粗制自行车。

*编辑经过足够多次的游戏，我正处于目标的边缘。我唯一的问题是，在插入所有内容并将线条粗细设置为x-number之后，由于“方法组”，它会给我一个错误，因为它无法分配数字

Form1代码

    }

    private void Form1_Paint(object sender, PaintEventArgs e)
    {
        Graphics g = e.Graphics;





        LineOne l1 = new LineOne(new PointF(50, 40));
        l1.setFilledState(false);
        l1.setLineColor(Color.Black);
        l1.setLineThickness = (6);
        //cannot assign to 'setLineThickness' because it is a method group'
        l1.Draw(g);


        sRectangle r2 = new sRectangle(new PointF(151, 160));
        r2.setFilledState(true);
        r2.setLineColor(Color.Green);
        r2.setFilledColor(Color.Honeydew);
        r2.Draw(g);

        sRectangleEmpty r1 = new sRectangleEmpty(new PointF(150, 150));
        r1.setFilledState(false);
        r1.setLineColor(Color.Blue);
        r1.Draw(g);

        sCircle c1 = new sCircle(new PointF(180, 130));
        c1.setFilledState(true);
        c1.setLineColor(Color.Orange);
        c1.setFilledColor(Color.Ivory);
        c1.Draw(g);

        c2.setFilledState(false);

Answer 1

setLineThickness是一个方法，而不是属性。

将l1.setLineThickness = (6);更改为l1.setLineThickness(6);（即删除等号）

Answer 2

找到它后，在审阅了一篇关于Overloads的文章后，我的行代码应该是

public override void Draw(Graphics g)
{

    g.DrawLine(pen, new Point(0, 0), new Point(120, 95));

}

当我使用l1.setLineThickness（1）玩时，我现在得到不同的线条笔划;在我的表格代码中。
