![]() | GetLifetimeService() | Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.) |
![]() | GetObjectData(SerializationInfo, StreamingContext) | 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 WebResponse.GetObjectData(SerializationInfo, StreamingContext).) |
![]() | GetResponseHeader(String) | Gets the contents of a header that was returned with the response. |
![]() | GetResponseStream() | Gets the stream that is used to read the body of the response from the server.(Overrides WebResponse.GetResponseStream().) |
![]() | GetType() | |
![]() | InitializeLifetimeService() | Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.) |
![]() | MemberwiseClone() | |
![]() | MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object.(Inherited from MarshalByRefObject.) |

| Name | Description | |
|---|---|---|
![]() ![]() | ISerializable.GetObjectData(SerializationInfo, StreamingContext) | 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.
Note |
|---|
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.
Header | Property |
|---|---|
Content-Encoding | |
Content-Length | |
Content-Type | |
Last-Modified | |
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.
