Remarks

XML Web services discovery involves discovering the available XML Web services given an URL. The URL typically points to a discovery document, which usually has a.disco file name extension. The discovery document contains references to information about the existence of XML Web services, such as Service Descriptions, XML Schema Definition language (XSD) schemas, or other discovery documents. This class represents a reference to a discovery document.

Constructors

DiscoveryDocumentReference()	Initializes a new instance of the DiscoveryDocumentReference class.
DiscoveryDocumentReference(String)	Initializes a new instance of the DiscoveryDocumentReference class, setting the Ref property to the value of `href`.

Properties

ClientProtocol	Gets or sets the instance of DiscoveryClientProtocol used in a discovery process. (Inherited from DiscoveryReference)
DefaultFilename	Gets the name of the default file to use when saving the referenced discovery document.
Document	Gets the contents of the referenced discovery document as a DiscoveryDocument object.
Ref	Gets or sets the reference to a discovery document.
Url	Gets or sets the URL of the referenced discovery document.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ReadDocument(Stream)	Reads and returns the discovery document from the passed Stream.
Resolve()	Downloads the referenced document at Url to resolve whether the referenced document is valid. (Inherited from DiscoveryReference)
Resolve(String, Stream)	Resolves whether the referenced document is valid. (Inherited from DiscoveryReference)
ResolveAll()	Verifies that all referenced documents within the discovery document are valid.
ToString()	Returns a string that represents the current object. (Inherited from Object)
WriteDocument(Object, Stream)	Writes the passed DiscoveryDocument into the passed Stream.
