How to set the WPF StrokeDashArray from Code behind?
提问by 0070
Can i know how to set the StrokeDashArray from code behind? I try to use the method like the way how to set the margin...but it doesn't work.
我可以知道如何从后面的代码设置 StrokeDashArray 吗？我尝试使用类似于如何设置边距的方法......但它不起作用。
The following is my code:
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);
}

Problem is this line
问题是这条线
myCircle.StrokeDashArray = new System.Windows.Thickness("2,2,2,2");
StrokeDashArray is a DoubleCollection
StrokeDashArray 是一个DoubleCollection
Try this instead
试试这个
myCircle.StrokeDashArray = new DoubleCollection() { 2 };
