NameDescription
System_CAPS_pubmethod HttpWebResponse

Obsolete. Initializes a new instance of the HttpWebResponse class.

System_CAPS_protmethod HttpWebResponse

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

NameDescription
System_CAPS_pubproperty

Gets the character set of the response.

System_CAPS_pubproperty

Gets the method that is used to encode the body of the response.

System_CAPS_pubproperty

Gets the length of the content returned by the request.(Overrides .)

System_CAPS_pubproperty

Gets the content type of the response.(Overrides .)

System_CAPS_pubproperty

Gets or sets the cookies that are associated with this response.

System_CAPS_pubproperty

Gets the headers that are associated with this response from the server.(Overrides .)

System_CAPS_pubproperty

Gets a Boolean value that indicates whether this response was obtained from the cache.(Inherited from WebResponse.)

System_CAPS_pubproperty

Gets a Boolean value that indicates whether both client and server were authenticated.(Overrides .)

System_CAPS_pubproperty

Gets the last date and time that the contents of the response were modified.

System_CAPS_pubproperty

Gets the method that is used to return the response.

System_CAPS_pubproperty

Gets the version of the HTTP protocol that is used in the response.

System_CAPS_pubproperty

Gets the URI of the Internet resource that responded to the request.(Overrides .)

System_CAPS_pubproperty

NameDescription
System_CAPS_pubmethod Close

Closes the response stream.(Overrides WebResponseClose.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Dispose

Releases the unmanaged resources used by the WebResponse object.(Inherited from WebResponse.)

System_CAPS_protmethod Dispose

Releases the unmanaged resources used by the HttpWebResponse, and optionally disposes of the managed resources.(Overrides WebResponseDispose.)

System_CAPS_pubmethod Equals

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethod Finalize

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethod GetHashCode

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethod GetLifetimeService

Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.)

System_CAPS_protmethod GetObjectData

This API supports the product infrastructure and is not intended to be used directly from your code. Populates a SerializationInfo with the data needed to serialize the target object.(Overrides WebResponseGetObjectData.)

System_CAPS_pubmethod GetResponseHeader

Gets the contents of a header that was returned with the response.

System_CAPS_pubmethod GetResponseStream

Gets the stream that is used to read the body of the response from the server.(Overrides WebResponseGetResponseStream.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod InitializeLifetimeService

Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.)

System_CAPS_protmethod MemberwiseClone

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethod MemberwiseClone

Creates a shallow copy of the current MarshalByRefObject object.(Inherited from MarshalByRefObject.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod ISerializableGetObjectData

This API supports the product infrastructure and is not intended to be used directly from your code. Serializes this instance into the specified SerializationInfo object.

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.

System_CAPS_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 HttpWebRequestGetResponse. You must call either the StreamClose or the HttpWebResponseClose method to close the response and release the connection for reuse. It is not necessary to call both StreamClose and HttpWebResponseClose, 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 property as name/value pairs.

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

Server

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.

HttpWebRequest HttpWReq = 
(HttpWebRequest)WebRequest.Create("http://www.contoso.com");

HttpWebResponse HttpWResp = (HttpWebResponse)HttpWReq.GetResponse();
// Insert code that uses the response object.
HttpWResp.Close();
Dim HttpWReq As HttpWebRequest = _
   CType(WebRequest.Create("http://www.contoso.com"), HttpWebRequest)

Dim HttpWResp As HttpWebResponse = _
   CType(HttpWReq.GetResponse(), HttpWebResponse)
' Insert code that uses the response object.
HttpWResp.Close()
HttpWebRequest^ HttpWReq = dynamic_cast<HttpWebRequest^>(WebRequest::Create( "http://www.contoso.com" ));
HttpWebResponse^ HttpWResp = dynamic_cast<HttpWebResponse^>(HttpWReq->GetResponse());

// Insert code that uses the response object.
HttpWResp->Close();
