Remarks

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

You should never directly create an instance of the HttpWebResponse class. Instead, use the instance returned by a call to HttpWebRequest..::.BeginGetResponse.

You must call either the Close or Stream..::.Close method to close the response and release the connection for reuse. It is not necessary to call both the Close and the Stream..::.Close method, 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. Headers for the request can be read from the Headers property as name/value pairs.

The following table shows the values that are available through properties of the HttpWebResponse class.

Header	Property
HTTP method	Method
Status code	StatusCode
Status description	StatusDescription

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