Specifies the base class for all XML Web service client proxies created using ASP.NET.
Assembly: System.Web.Services (in System.Web.Services.dll)
Thetype exposes the following members.
|CanRaiseEvents||Gets a value indicating whether the component can raise an event. (Inherited from Component.)|
|ConnectionGroupName||Gets or sets the name of the connection group for the request.|
|Container||Gets the IContainer that contains the Component. (Inherited from Component.)|
|Credentials||Gets or sets security credentials for XML Web service client authentication.|
|DesignMode||Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)|
|Events||Gets the list of event handlers that are attached to this Component. (Inherited from Component.)|
|PreAuthenticate||Gets or sets whether pre-authentication is enabled.|
|RequestEncoding||The Encoding used to make the client request to the XML Web service.|
|Site||Gets or sets the ISite of the Component. (Inherited from Component.)|
|Timeout||Indicates the time an XML Web service client waits for the reply to a synchronous XML Web service request to arrive (in milliseconds).|
|Url||Gets or sets the base URL of the XML Web service the client is requesting.|
|UseDefaultCredentials||Gets or sets a value that indicates whether to set the Credentials property to the value of the CredentialCache.DefaultCredentials property.|
|Abort||Cancels a request to an XML Web service method.|
|AddToCache||Add an instance of the client protocol handler to the cache.|
|CreateObjRef||Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)|
|Dispose()||Releases all resources used by the Component. (Inherited from Component.)|
|Dispose(Boolean)||Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Inherited from Component.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)|
|GetFromCache||Gets an instance of a client protocol handler from the cache.|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetLifetimeService||Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|GetService||Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetWebRequest||Creates a WebRequest instance for the specified uri. This protected method is called by the XML Web service client infrastructure to get a new WebRequest transport object to transmit the XML Web service request.|
|GetWebResponse(WebRequest)||Returns a response from a synchronous request to an XML Web service method.|
|GetWebResponse(WebRequest, IAsyncResult)||Returns a response from an asynchronous request to an XML Web service method. This protected method is called by the XML Web service client infrastructure to get the response from an asynchronous XML Web service request.|
|InitializeLifetimeService||Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|MemberwiseClone()||Creates a shallow copy of the current Object. (Inherited from Object.)|
|MemberwiseClone(Boolean)||Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)|
|ToString||Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.)|
The properties of the class are used to control the behavior of the transport used to transmit the XML Web service request and response. The properties on this class map to properties found on WebRequest. Instances of classes deriving from WebRequest, such as HttpWebRequest, are used as the transport mechanism for XML Web services created using ASP.NET.
To communicate with an XML Web service, you must create a proxy class deriving indirectly or directly from for the XML Web service you want to call. Instead of creating the proxy class manually, you can use the Wsdl.exe tool to create a proxy class for a given XML Web service's service description. Since is the base class for your client proxy, you will find its properties on your proxy classes. These properties are useful for controlling the request behavior of the underlying transport. For instance, use the Credentials property for calling authenticated XML Web services. Many of the properties are used to initialize the WebRequest object that is used to make the Web request.
The following example is an ASP.NET Web Form, which calls an XML Web service named Math. Within the EnterBtn_Click function, the Web Form sets proxy information and client credentials on the proxy class prior to calling the remote XML Web service method.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
The properties on this class are copied into a new instance of a WebRequest object for each XML Web service method call. While you can call XML Web service methods on the same instance from different threads at the same time, there is no synchronization done to ensure that a consistent snapshot of the properties will get transferred to the WebRequest object. Therefore if you need to modify the properties and make concurrent method calls from different threads you should use a different instance of the XML Web service proxy or provide your own synchronization.
