.net 如何使用从代码behing到WPF的变量（string/integer/double）

如何从代码behing到WPF使用variablestring/integer/double

例如，在我的情况下，我有这个故事板

          <Storyboard x:Key="volumerecdown">
                <DoubleAnimation Duration="00:00:00.5" AccelerationRatio="0.5" DecelerationRatio="0.5" 
                Storyboard.TargetProperty="Height" To="STRING_FROM_CODE_BEHIND"/>
          </Storyboard>

---

但不起作用

您必须使用属性

    Private _height_rec As Integer
    Public Property height_rec As Integer
    Get
        Return _height_rec
    End Get
    Set(ByVal value As Integer)
        _height_rec = value
    End Set
    End height_rec 

在xaml中输入以下内容：

 <Storyboard x:Key="volumerecdown">
                <DoubleAnimation Duration="00:00:00.5" AccelerationRatio="0.5" DecelerationRatio="0.5" 
                Storyboard.TargetProperty="Height" To="{Binding height_rec}"/>
          </Storyboard>

仍然不起作用，必须用End属性替换End height_rec，没有错误，但情节提要没有任何作用

 <Storyboard x:Key="volumerecdown">
                <DoubleAnimation Duration="00:00:00.5" AccelerationRatio="0.5" DecelerationRatio="0.5" 
                Storyboard.TargetProperty="Height" To="{Binding height_rec}"/>
          </Storyboard>
