绘制一个按钮的Click线

我不想让用户画一条线，就像我们绘制在涂料中的应用以下是我的代码

XAML代码为MainWindow.xaml 

<Window x:Class="LineWPF.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="350" Width="525">

    <DockPanel LastChildFill="True">

        <Button Name="buttonToolLine" DockPanel.Dock="Top" Height="41" MouseDown="buttonToolLine_MouseDown" MouseMove="buttonToolLine_MouseMove">Line</Button>

            <Canvas Name="DrawingCanvas"></Canvas>

    </DockPanel>

 

</Window>

以下是我的背后，代码MainWindow.xaml.cs

{C}
我怎么错过了这里，MouseDown事件也打不中我调试时，还有新的编码，特别是在WPF和图形请帮忙

为什么你注册MouseDown和MouseMove事件的Button？它看起来像你必须注册画布事件
