XmlSchemaProviderAttribute Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

When applied to a type that implements the IXmlSerializable interface, stores the name of a static method of the type that returns an XML schema and a XmlQualifiedName (or XmlSchemaType for anonymous types) that controls the serialization of the type.

Inheritance Hierarchy

System.Object
System.Attribute
System.Xml.Serialization.XmlSchemaProviderAttribute

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

Syntax

'Declaration
<AttributeUsageAttribute(AttributeTargets.Class Or AttributeTargets.Struct Or AttributeTargets.Interface)> _
Public NotInheritable Class XmlSchemaProviderAttribute _
    Inherits Attribute

[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Interface)]
public sealed class XmlSchemaProviderAttribute : Attribute

The XmlSchemaProviderAttribute type exposes the following members.

Constructors

	Name	Description
	XmlSchemaProviderAttribute	Initializes a new instance of the XmlSchemaProviderAttribute class for a specified static method in the target type.

Properties

	Name	Description
	IsAny	Gets or sets a value that determines whether the target class is a wildcard, or that the schema for the class contains only an xs:any element.
	MethodName	Gets the name of the static method that supplies the type's XML schema and the name of its XML Schema data type.

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The target class of the attribute must implement the IXmlSerializable interface.

An anonymous complex type cannot be created using a method that returns XmlQualifiedName. Because an anonymous type has no name, and you cannot add an anonymous type to a schema, the anonymous type must be returned as an XmlSchemaType.


In Silverlight 5, schema information is not used. However, the XmlSchemaProviderAttribute is still relevant, because, when IsAny is set to true or when the static method returns nulla null reference (Nothing in Visual Basic), the serializer will treat the type differently. For more information, see XML and ADO.NET Types in Data Contracts.
