FtpWebRequest.KeepAlive Property

Gets or sets a Boolean value that specifies whether the control connection to the FTP server is closed after the request completes.

Namespace:  System.Net
Assembly:  System (in System.dll)

public function get KeepAlive () : boolean 
public function set KeepAlive (value : boolean)

Property Value

Type: System.Boolean
true if the connection to the server should not be destroyed; otherwise, false. The default value is true.

ExceptionCondition
InvalidOperationException

A new value was specified for this property for a request that is already in progress.

When the KeepAlive property is set to false, the control connection is closed when you call the Close method.

Changing KeepAlive after calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method causes an InvalidOperationException exception.
