HttpWebResponse Class

Provides an HTTP-specific implementation of the WebResponse class.

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

[<SerializableAttribute>]
type HttpWebResponse =  
    class
        inherit WebResponse
        interface ISerializable
    end

The HttpWebResponse type exposes the following members.

  NameDescription
Protected methodHttpWebResponse Obsolete. Initializes a new instance of the HttpWebResponse class from the specified SerializationInfo and StreamingContext instances.

This class contains support for HTTP-specific uses of the properties and methods of the WebResponse class. The HttpWebResponse class is used to build HTTP stand-alone client applications that send HTTP requests and receive HTTP responses.

NoteNote

Do not confuse HttpWebResponse with the HttpResponse class that is used in ASP.NET applications and whose methods and properties are exposed through ASP.NET's intrinsic Response object.

You should never directly create an instance of the HttpWebResponse class. Instead, use the instance returned by a call to HttpWebRequest.GetResponse. You must call either the Stream.Close or the HttpWebResponse.Close method to close the response and release the connection for reuse. It is not necessary to call both Stream.Close and HttpWebResponse.Close, but doing so does not cause an error.

Common header information returned from the Internet resource is exposed as properties of the class. See the following table for a complete list. Other headers can be read from the Headers property as name/value pairs.

The following table shows the common HTTP headers that are available through properties of the HttpWebResponse class.

The contents of the response from the Internet resource are returned as a Stream by calling the GetResponseStream method.

The following example returns an HttpWebResponse from an HttpWebRequest.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
