如何从代码中设置WPF StrokeDashArray？

Question

我可以知道如何从代码后面设置StrokeDashArray吗？我尝试使用方法,如如何设置边距...但它不起作用.

以下是我的代码:

public static void DrawCircle(MainWindow main)
    {
        Ellipse myCircle = new Ellipse();
        myCircle.Stroke = Brushes.Orange;
        myCircle.Width = 25;
        myCircle.Height = 25;
        myCircle.StrokeThickness = 2;
        myCircle.StrokeDashArray = new System.Windows.Thickness("2,2,2,2");

        Canvas.SetLeft(myCircle, 10);
        Canvas.SetRight(myCircle, 10);
        Canvas.SetBottom(myCircle, 20);
        Canvas.SetTop(myCircle, 20);
        main.MyCanvas.Children.Add(myCircle);

    }

Answer 1

问题是这一行

myCircle.StrokeDashArray = new System.Windows.Thickness("2,2,2,2");

StrokeDashArray是一个DoubleCollection

试试这个

myCircle.StrokeDashArray = new DoubleCollection() { 2 };
