我是WPF的新手,需要将一行绑定到2个点。
但是下面的代码不起作用:
<Canvas>
<Ellipse x:Name="dot1" Width="5" Height="5"
Canvas.Left="50" Canvas.Top="50"/>
<Ellipse x:Name="dot2" Width="5" Height="5"
Canvas.Left="100" Canvas.Top="100"/>
<Line
X1="{Binding ElementName='dot1', Path='Canvas.Left'}"
Y1="{Binding ElementName='dot1', Path='Canvas.Top'}"
X2="{Binding ElementName='dot2', Path='Canvas.Left'}"
Y2="{Binding ElementName='dot2', Path='Canvas.Top'}"/>
</Canvas>
错误在哪里?谢谢!

我认为你得到的错误是因为单引号“'”,我认为它应该是这样的
<Line
X1="{Binding ElementName=dot1, Path=Canvas.Left}"
Y1="{Binding ElementName=dot1, Path=Canvas.Top}"
X2="{Binding ElementName=dot2, Path=Canvas.Left}"
Y2="{Binding ElementName=dot2, Path=Canvas.Top}"/>
如果它不起作用尝试这种替代语法,只需解决一下: EX:
< TextBox Name="TextBox1">
< TextBox.Text>
< Binding ElementName="Slider1" Path="Value" />
< /TextBox.Text>
< /TextBox>

<Line Stroke="Black" StrokeThickness="1"
X1="{Binding ElementName=dot1, Path=(Canvas.Left)}"
Y1="{Binding ElementName=dot1, Path=(Canvas.Top)}"
X2="{Binding ElementName=dot2, Path=(Canvas.Left)}"
Y2="{Binding ElementName=dot2, Path=(Canvas.Top)}"/>
