microsoft-metro - Draw a line in C# for metro app

Question

I am trying to draw a line in a windows 8 app in c#. However, when I try to use

Line myLine = new Line(); it does not work and tells me the namespace does not exist.

Using LineGeometery myLine = new LineGeometery (); does appear to create a new line and I can set the start and end points. However, as I cannot set the stroke, I really do not know if this is the correct approach. In fact, I am unsure on the difference between LineGeometery() and Line().

If anyone could help, that would be very appreciated.

请在您的应用程序中添加以下使用。Windows.UI.Xaml.Shapes

Line 类位于 Windows.UI.Xaml.Shapes 命名空间中。

这是我用来向名为 LayoutRoot 的网格添加一条线的代码部分

Line line = new Line();
line.X1 = 10;
line.X2 = 200;
line.Y1 = 10;
line.Y2 = 200;
line.Stroke = new SolidColorBrush(Colors.Red);
LayoutRoot.Children.Add(line);
