The base class for discoverable references using XML Web services discovery.
System::Object
System.Web.Services.Discovery::DiscoveryReference
System.Web.Services.Discovery::ContractReference
System.Web.Services.Discovery::DiscoveryDocumentReference
System.Web.Services.Discovery::SchemaReference
System.Web.Services.Discovery::DiscoveryReference

Assembly: System.Web.Services (in System.Web.Services.dll)
The DiscoveryReference type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ClientProtocol | Gets or sets the instance of DiscoveryClientProtocol used in a discovery process. |
![]() | DefaultFilename | Gets the name of the default file to use when saving the referenced discovery document, XSD schema, or Service Description. |
![]() | Url | Gets or sets the URL of the referenced document. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | FilenameFromUrl | Returns a file name based on the passed URL. |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (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 | Reads the passed Stream and returns an instance of the class representing the type of referenced document. |
![]() | Resolve() | Downloads the referenced document at Url to resolve whether the referenced document is valid. |
![]() | Resolve(String, Stream) | Resolves whether the referenced document is valid. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | WriteDocument | When overridden in a derived class, writes the document to a Stream. |
ContractReference, SchemaReference, and DiscoveryDocumentReference all inherit from DiscoveryReference, and represent the three types of documents discoverable through XML Web services discovery: Service Descriptions, XML Schema Definition (XSD) schemas, and discovery documents, respectively.
