WebReference Class

Describes a reference to a collection of XML Web services.


Namespace:  System.Web.Services.Description
Assembly:  System.Web.Services (in System.Web.Services.dll)

public sealed class WebReference

The WebReference type exposes the following members.

Public methodWebReference(DiscoveryClientDocumentCollection, CodeNamespace)Initializes a new instance of the WebReference class with the given description document collection and proxy code namespace.
Public methodWebReference(DiscoveryClientDocumentCollection, CodeNamespace, String, String)Initializes a new instance of the WebReference class with the given data.
Public methodWebReference(DiscoveryClientDocumentCollection, CodeNamespace, String, String, String)Initializes a new instance of the WebReference class with the given data.

Public propertyAppSettingBaseUrlGets the base URL of the Web reference.
Public propertyAppSettingUrlKeyGets the URL key of the web reference.
Public propertyDocumentsGets the collection of description documents associated with the Web reference.
Public propertyProtocolNameGets or sets the protocol associated with the Web reference.
Public propertyProxyCodeGets the code namespace associated with the Web reference.
Public propertyValidationWarningsGets a collection of warnings generated when validating the description documents.
Public propertyWarningsGets a collection of warnings generated when importing Web Services Description Language (WSDL) service description documents.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

A WebReference object is used to pass information about a set of Web services to the static GenerateWebReferences method of the ServiceDescriptionImporter class.

The following code example illustrates the use of this class.
