Provides the XAML type system identifier for a member if the member is also a XAML directive. XAML readers and XAML writers use the XamlDirective identifier during processing of member nodes. The identifier is used when the XAML reader is positioned on a StartMember and IsDirective is true.

Remarks

XamlDirective provides expected values for the XAML type system when the member is a XAML directive. By definition, a XAML directive has characteristics that always return the same results for a subset of the XamlMember properties, and the same XAML type system information is reported for all possible XAML directives. The reporting of XAML type system characteristics that are specific to directives is accomplished by internal behavior or through overrides of XamlMember Lookup* virtual members in the XamlDirective class.

The following list shows the returned results of a XAML directive for XamlMember when the member is actually a XamlDirective:

LookupCustomAttributeProvider is always null.
DeferringLoader is always null.
DependsOn is always null.
IsAmbient is always false.
IsAttachable is always false.
IsDirective is always true.
IsEvent is always false.
IsReadOnly is always false.
IsReadPublic is always true.
IsWritePublic is always true.

Also, the internal backing for DeclaringType remains unset and returns null.

Important

XamlDirective is a XamlMember subclass. As with XamlMember, XamlDirective has security considerations regarding how the XAML type system reports access. See XamlMember.

Constructors

XamlDirective(IEnumerable<String>, String, XamlType, XamlValueConverter<TypeConverter>, AllowedMemberLocations)	Initializes a new instance of the XamlDirective class, specifying values for each per-case value of a XamlDirective.
XamlDirective(String, String)	Initializes a new instance of the XamlDirective class, specifying values for a name and a single XAML namespace. Use this signature only when you want or expect IsUnknown to report `true` for the directive.

Properties

AllowedLocation	Gets a value that specifies the XAML node types where the directive can be specified.
DeclaringType	Gets the XamlType for the type that declares the member that is associated with this XamlMember. (Inherited from XamlMember)
DeferringLoader	Gets a XamlValueConverter<TConverterBase> object, which is used for deferred loading of XAML declared objects. (Inherited from XamlMember)
DependsOn	Gets a list of XamlMember objects. These report the members where dependency relationships for initialization order exist relative to this XamlMember. (Inherited from XamlMember)
Invoker	Gets the XamlMemberInvoker implementation that is associated with this XamlMember. (Inherited from XamlMember)
IsAmbient	Gets a value that indicates whether this XamlMember is reported as an ambient property. (Inherited from XamlMember)
IsAttachable	Gets a value that indicates whether this XamlMember is an attachable member. (Inherited from XamlMember)
IsDirective	Gets a value that indicates whether this XamlMember is a XAML directive. (Inherited from XamlMember)
IsEvent	Gets a value that indicates whether this XamlMember represents an event member. (Inherited from XamlMember)
IsNameValid	Gets a value that indicates whether this XamlMember is initialized with a valid `xamlName` string as its Name. (Inherited from XamlMember)
IsReadOnly	Gets a value that indicates whether this XamlMember represents a read-only member. (Inherited from XamlMember)
IsReadPublic	Gets a value that indicates whether this XamlMember represents a member with a callable public `get` accessor. (Inherited from XamlMember)
IsUnknown	Gets a value that indicates whether the member is not resolvable by the backing system that is used for type and member resolution. (Inherited from XamlMember)
IsWriteOnly	Gets a value that indicates whether this XamlMember represents a write-only member. (Inherited from XamlMember)
IsWritePublic	Gets a value that indicates whether this XamlMember represents a member that has a callable public `set` accessor. (Inherited from XamlMember)
MarkupExtensionBracketCharacters	Defines the opening and closing bracket characters for a markup extension. (Inherited from XamlMember)
Name	Gets the `xamlName` name string that declares this XamlMember. (Inherited from XamlMember)
PreferredXamlNamespace	Gets the single XAML namespace URI that identifies the primary XAML namespace for this XamlMember. (Inherited from XamlMember)
SerializationVisibility	Gets a DesignerSerializationVisibility value, which indicates how a visual designer should process the member. (Inherited from XamlMember)
TargetType	Gets the XamlType of the type where the XamlMember can exist. (Inherited from XamlMember)
Type	Gets the XamlType of the type that is used by the member. (Inherited from XamlMember)
TypeConverter	Gets a XamlValueConverter<TConverterBase> object, which can be used for type conversion construction of XAML declared objects. (Inherited from XamlMember)
UnderlyingMember	Gets the CLR type system MemberInfo that is available for a member that is constructed by PropertyInfo, MethodInfo, or EventInfo. (Inherited from XamlMember)
ValueSerializer	Gets a XamlValueConverter<TConverterBase> object, which is used for value serialization of XAML declared objects. (Inherited from XamlMember)

Methods

Equals(Object)	Indicates whether the current object is equal to another object. (Inherited from XamlMember)
Equals(XamlMember)	Indicates whether the current object is equal to another object of the same type. (Inherited from XamlMember)
