XmlAnyAttributeAttribute Class

 

Specifies that the member (a field that returns an array of XmlAttribute objects) can contain any XML attributes.

Namespace:   System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

System.Object
  System.Attribute
    System.Xml.Serialization.XmlAnyAttributeAttribute

[<AttributeUsageAttribute(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter | AttributeTargets.ReturnValue,
    AllowMultiple = false)>]
type XmlAnyAttributeAttribute = 
    class
        inherit Attribute
    end

NameDescription
System_CAPS_pubmethodXmlAnyAttributeAttribute()

Constructs a new instance of the XmlAnyAttributeAttribute class.

NameDescription
System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodIsDefaultAttribute()

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

System_CAPS_pubmethodMatch(Object)

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

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

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

NameDescription
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.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

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.)

Use the XmlAnyAttributeAttribute to contain arbitrary data (as XML attributes) that is sent as part of an XML document, such as, metadata sent as part of the document.

Apply the XmlAnyAttributeAttribute to a field that returns an array of XmlAttribute or XmlNode objects. When the Deserialize method of the XmlSerializer class is called, all XML attributes that do not have a corresponding member in the class being deserialized are collected in the array. After deserialization, you can iterate through the collection of XmlAttribute items to process the data.

The UnknownNode and UnknownAttribute events of the XmlSerializer do not occur if you apply the XmlAnyAttributeAttribute to a member of a class.

System_CAPS_noteNote

You can use the word XmlAnyAttribute in your code instead of the longer XmlAnyAttributeAttribute.

For more information about using attributes, see Extending Metadata Using Attributes.

The following example collects all unknown attributes into an array of XmlAttribute objects. To try the example, create a file named UnknownAttributes.xml that contains the following XML:

<?xml version="1.0" encoding="utf-8"?>
<Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
GroupType = 'Technical' GroupNumber = '42' GroupBase = 'Red'>
  <GroupName>MyGroup</GroupName>
</Group>
