c# - 添加 x :Key attribute using Linq to Xml

Question

我正在尝试使用 Linq to XML 在某些 XAML 中设置 x:Key，以便我可以将值转换器添加到数据模板的资源字典中:

 XNamespace xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation";
 XNamespace local = "clr-namespace:App,assembly=App";
 XElement dt = new XElement(xmlns + "DataTemplate",
     new XAttribute(XNamespace.Xmlns + "x", "http://schemas.microsoft.com/winfx/2006/xaml"),
     new XAttribute(XNamespace.Xmlns + "local", "clr-namespace:App,assembly=App"),
     new XElement(xmlns + "DataTemplate.Resources",
         new XElement(local + "MyConverter",
             new XAttribute("x:Key", "myConverter"))));

然而，这引发了一个异常，提示“:”在属性名称中是不允许的。使用另一个 XNamespace x = "http://schemas.microsoft.com/winfx/2006/xaml" 并编写 x + "Key" 也不起作用 - 它给出 p3:Key。

有没有办法在 XAttribute 名称中包含一个冒号？

    XNamespace xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation";
    XNamespace local = "clr-namespace:App,assembly=App";
    XNamespace x = "http://schemas.microsoft.com/winfx/2006/xaml"; 

    XElement dt = new XElement(xmlns + "DataTemplate",
        new XAttribute(XNamespace.Xmlns + "x", "http://schemas.microsoft.com/winfx/2006/xaml"),
        new XAttribute(XNamespace.Xmlns + "local", "clr-namespace:App,assembly=App"),
        new XElement(xmlns + "DataTemplate.Resources",
            new XElement(local + "MyConverter",
                new XAttribute(x + "Key", "myConverter"))));

   Console.WriteLine(dt);

输出:

<DataTemplate xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:local="clr-namespace:App,assembly=App" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
  <DataTemplate.Resources>
    <local:MyConverter x:Key="myConverter" />
  </DataTemplate.Resources>
</DataTemplate>
