System.windows.freezablecollection 的 XAML 用法XAML Usage for FreezableCollection

FreezableCollection<T>支持有限XAMLXAML的语法。FreezableCollection<T> supports a limited XAMLXAML syntax.

  • 作为根对象的对象元素, 你可以在理论上指定一个FreezableCollection<T>不受约束的对象元素, 该元素还必须指定x:TypeArguments 指令以声明约束。As an object element at the root, you can theoretically specify an unconstrained FreezableCollection<T> object element, which must also specify the x:TypeArguments Directive to declare the constraint. 但是, 这不是一种常见方案, 因为为此, FreezableCollection<T>必须是根元素。However, this is not a common scenario, because to do this, the FreezableCollection<T> must be the root element. 存在此限制的原因XAMLXAML是, 中WPFWPF的处理器实现仅支持x:TypeArguments 指令, 而它所设置的元素是根元素, 并且如果要在中XAMLXAML实例化泛型类型。This limitation exists because the XAMLXAML processor implementation in WPFWPF can only support x:TypeArguments Directive when the element it is being set on is the root element, and you must use on any open constraint generic if you want to instantiate a generic type in XAMLXAML. 不太可能需要将FreezableCollection<T>作为根元素, 甚至是松散。 XAMLXAMLIt is unlikely that you want a FreezableCollection<T> as the root element, even as loose XAMLXAML.

  • 如果派生自FreezableCollection<T>并在派生集合中应用类型约束, 则派生集合可以支持各种用法。If you derive from FreezableCollection<T> and apply a type constraint in the derived collection, the derived collection can support a variety of usages. 这是可能的, 因为派生的约束不再需要通过。This is possible because the constraint in your derivation eliminates the need to pass .

    • 此类XAMLXAML派生集合的典型用法是通过隐式集合语法。The typical XAMLXAML usage for such a derived collection is through implicit collection syntax. 支持某些接口的集合不需要将集合本身指定为对象元素。Collections that support certain interfaces do not need to specify the collection itself as an object element. 有关中XAMLXAML的集合语法的详细信息, 请参阅XAML 语法详述For details on collection syntax in XAMLXAML, see XAML Syntax In Detail. 例如, 如果对象的属性的类型为受约束FreezableCollection<T> DependencyObject的类型, 则该对象可能支持以下语法:For instance, an object with a property where the property was of type FreezableCollection<T> constrained by DependencyObject could support the following syntax:

      <object>  
        <object.property>  
          oneOrMoreDependencyObjectElements  
        </object.property>  
      </object>  
      
    • 只要不隐藏无参数构造函数, 派生的集合也可以支持对象元素语法 (其中对象元素是显式的, 而不是上面所示的隐式用法)。As long as you do not hide the parameterless constructor, the derived collection can also support an object element syntax (where the object element is explicit, as opposed to the implicit usage shown above). 它不需要是根元素。It does not need to be the root element. 或者, 您也可以使用派生集合作为根元素, 而无需指定, 尽管使用集合作为根元素的情况并不常见。Or, you can also use the derived collection as a root element, without needing to specify , although using a collection as a root element is uncommon.

  • 在上述任何一种情况下, 集合中的任何子元素都必须为实现的约束的类型或由指定。Any child elements of the collection in either of the above scenarios must be of the type of either the implemented constraint, or as specified by .
