添加 RibbonGroup 时出现未处理的异常

我正在尝试在 WPF 应用程序中实现 Outlook 功能区，并且功能区工作正常。但是，当我尝试添加 RibbonGroup 时，我在 XAML 中遇到未处理的异常。

这是我的代码：

<r:RibbonWindow 
    x:Class="WpfArticles.Main"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
    Title="Main" Height="500" Width="500">

    <StackPanel>
        <r:Ribbon Title="WPF Ribbon - Document1" x:Name="ribbon" >
            <r:RibbonTab Label="Home">
                <r:RibbonGroup Name="Test" />
            </r:RibbonTab>
            <r:RibbonTab Label="Insert"/>
            <r:RibbonTab Label="Help"/>
        </r:Ribbon >

并且我在 XAML 中收到此错误：

I am trying to implement the Outlook Ribbon in a WPF application, and the ribbon works fine. However when I try to add a RibbonGroup, I get an unhandled exception in the XAML.

Here is my code:

<r:RibbonWindow 
    x:Class="WpfArticles.Main"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
    Title="Main" Height="500" Width="500">

    <StackPanel>
        <r:Ribbon Title="WPF Ribbon - Document1" x:Name="ribbon" >
            <r:RibbonTab Label="Home">
                <r:RibbonGroup Name="Test" />
            </r:RibbonTab>
            <r:RibbonTab Label="Insert"/>
            <r:RibbonTab Label="Help"/>
        </r:Ribbon >

and I am getting this error in the XAML :

What am I doing wrong? Without the <r:RibbonGroup Name="Test" /> it works fine!

Thanks for your help and time

我怀疑您使用的是旧版本，因为 Label 属性不再有效。可以找到最新版本 这里。

I suspect you are using an older version, as the Label property is no longer valid. The latest version can be found here.

我下载了该功能区，但由于某种原因无法添加参考。无论如何，我下载了一个示例，它明确表示如果该组为空，则会抛出异常。所以现在一切正常。感谢您的帮助！

I downloaded that ribbon but could not add the reference for some reason. Anyway, I downloaded an example and it clearly said that the Group will throw an exception if it is empty. So now everything works fine. Thanks for your help!
