我必须显示树视图，如上面的树所示。 1级项目是枚举，标量，布尔值，字符串，数组对象。我编写了templateSelector来为每个1级对象选择不同的模板。我能够为1级类型编写数据模板。但是如何为＆＃34;数组类型＆＃34;编写模板？因为它再次包含1级项目作为其项目（级别2）。 3级的同样问题。只允许3级。

<local:ParameterTemplateSelector x:Key="ParameterTemplateSelector"></local:ParameterTemplateSelector>
    <DataTemplate x:Key="ScalarTemplate">
        <StackPanel Orientation="Horizontal">
            <Label FontWeight="Bold" Width="80" Content="{Binding parameterCode}"></Label>
            <TextBox Text="{Binding Value.Item.Value}" Width="100" TextAlignment="Center"></TextBox>
        </StackPanel>
    </DataTemplate>
    <DataTemplate x:Key="EnumTemplate">
        <StackPanel Orientation="Horizontal">
            <Label FontWeight="Bold" Width="80" Content="{Binding parameterCode}"></Label>
            <TextBox Text="{Binding Value.Item.Value}" Width="100" TextAlignment="Center"></TextBox>
        </StackPanel>
    </DataTemplate>
    <DataTemplate x:Key="StringTemplate">
        <StackPanel Orientation="Horizontal">
            <Label FontWeight="Bold" Width="80" Content="{Binding parameterCode}"></Label>
            <TextBox Text="{Binding Value.Item}" Width="100" TextAlignment="Center"></TextBox>
        </StackPanel>
    </DataTemplate>
    <DataTemplate x:Key="BooleanTemplate">
        <StackPanel Orientation="Horizontal">
            <Label FontWeight="Bold" Width="80" Content="{Binding parameterCode}"></Label>

            <ComboBox Width="100" SelectedIndex="{Binding Value.Item, Converter={StaticResource boolToIndexConverter}}">
                <ComboBoxItem Tag="1">True</ComboBoxItem>
                <ComboBoxItem Tag="0">False</ComboBoxItem>
            </ComboBox>
            <!--<TextBox Text="{Binding Value.Item}" Width="100" TextAlignment="Center"></TextBox>-->
        </StackPanel>
    </DataTemplate>
