ContentWrapperAttribute Class


Specifies one or more types on the associated collection type that will be used to wrap foreign content.

Namespace:   System.Windows.Markup
Assembly:  System.Xaml (in System.Xaml.dll)


[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = true, 
	Inherited = true)]
public sealed class ContentWrapperAttribute : Attribute


Initializes a new instance of the ContentWrapperAttribute class.


Gets the type that is declared as a content wrapper for the collection type associated with this attribute.


Gets a unique identifier for this attribute. (Overrides Attribute.TypeId.)


Determines whether the specified ContentWrapperAttribute is equivalent this ContentWrapperAttribute by comparing the ContentWrapper properties.(Overrides Attribute.Equals(Object).)


Gets a hash code for this instance.(Overrides Attribute.GetHashCode().)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Foreign content refers to cases where the type system constraints on the type of the content property do not capture all of the possible content cases that XAML usage for the owning type would support. For example, XAML support for content of a particular type might support strings in a strongly typed generic Collection<T>.

InlineCollection is an example of a WPF class that has the ContentWrapperAttribute attribute applied. In this case there are two separate attributed wrapper classes.

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, ContentWrapperAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.
