Properties

	Name	Description
	ContentLength	When overridden in a descendant class, gets or sets the content length of data being received. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by ContentLength. In XNA Framework, this member is overridden by ContentLength.
	ContentType	When overridden in a derived class, gets or sets the content type of the data being received. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by ContentType. In XNA Framework, this member is overridden by ContentType.
	Cookies	Gets the cookies used to persist state information for the HTTP response.
	Headers	When overridden in a derived class, gets a collection of header name-value pairs associated with this request. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by Headers. In XNA Framework, this member is overridden by Headers.
	Method	Gets the method that is used to return the response.
	ResponseUri	When overridden in a derived class, gets the URI of the Internet resource that actually responded to the request. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by ResponseUri. In XNA Framework, this member is overridden by ResponseUri.
	StatusCode	Gets the status of the response.
	StatusDescription	Gets the status description returned with the response.
	SupportsHeaders	Gets a value that indicates whether the Headers property is supported by the descendant class for the WebResponse instance. (Inherited from WebResponse.)

Methods

	Name	Description
	Close	When overridden by a descendant class, closes the response stream. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by Close(). In XNA Framework, this member is overridden by Close().
	Dispose()	Releases the resources used by the current instance of the WebResponse class. (Inherited from WebResponse.)
	Dispose(Boolean)	Called by the Dispose() and Finalize() methods to release the managed and unmanaged resources used by the current instance of the WebResponse class. (Inherited from WebResponse.) In Silverlight for Windows Phone Windows Phone OS 7.1, this member is Dispose(Boolean).
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetResponseStream	When overridden in a descendant class, returns the data stream from the Internet resource. (Inherited from WebResponse.) In Silverlight for Windows Phone, this member is overridden by GetResponseStream(). In XNA Framework, this member is overridden by GetResponseStream().
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

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 HTTP stand-alone client 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.
