WebRequest.BeginGetResponse Method

When overridden in a descendant class, begins an asynchronous request for an Internet resource.

Namespace:  System.Net
Assembly:  System.Net (in System.Net.dll)

public virtual IAsyncResult BeginGetResponse(
	AsyncCallback callback,
	Object state
)

Parameters

callback
Type: System.AsyncCallback
The AsyncCallback delegate.
state
Type: System.Object
An object containing state information for this asynchronous request.

Return Value

Type: System.IAsyncResult
An IAsyncResult that references the asynchronous request.

ExceptionCondition
NotImplementedException

Any attempt is made to access the method, when the method is not overridden in a descendant class.

The BeginGetResponse method starts an asynchronous request for a response. The callback method that implements the AsyncCallback delegate uses the EndGetResponse method to return the WebResponse from the Internet resource.

NoteNote:

The WebRequest class is an abstract class. The actual behavior of a WebRequest instance at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest.

NoteNote:

If a WebException is thrown, use the Response and Status properties of the exception to determine the response from the server.
