The HttpWebResponse type exposes the following members.

Properties

	Name	Description
	ContentEncoding	Gets the method that is used to encode the body of the response.
	ContentLength	Gets the length of the content returned by the request. (Overrides WebResponse. . :: . .ContentLength.)
	ContentType	Gets the content type of the response. (Overrides WebResponse. . :: . .ContentType.)
	Headers	Gets the headers that are associated with this response from the server. (Overrides WebResponse. . :: . .Headers.)
	LastModified	Gets the last date and time that the contents of the response were modified.
	Method	Gets the method that is used to return the response.
	ProtocolVersion	Gets the version of the HTTP protocol that is used in the response.
	ResponseUri	Gets the URI of the Internet resource that responded to the request. (Overrides WebResponse. . :: . .ResponseUri.)
	Server	Gets the name of the server that sent the response.
	StatusCode	Gets the status of the response.
	StatusDescription	Gets the status description returned with the response.

Methods

	Name	Description
	Close	When overridden by a descendant class, closes the response stream. (Inherited from WebResponse.)
	Dispose() () () ()	Releases the unmanaged resources used by the WebResponse object. (Inherited from WebResponse.)
	Dispose(Boolean)	Releases the unmanaged resources used by the HttpWebResponse, and optionally disposes of the managed resources. (Overrides WebResponse. . :: . .Dispose(Boolean).)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Performs clean-up operations. (Inherited from WebResponse.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetResponseHeader	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	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..::..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	ContentEncoding
Content-Length	ContentLength
Content-Type	ContentType
Last-Modified	LastModified
Server	Server

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

Thread Safety

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