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 Property KeepAlive As Boolean
Dim instance As FtpWebRequest 
Dim value As Boolean 

value = instance.KeepAlive

instance.KeepAlive = value

Property Value

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


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.

The following code example retrieves and displays property values for a specified FtpWebRequest object.

Console::WriteLine(S"Passive: {0}  Keep alive: {1}  Binary: {2} Timeout: {3}.", __box(request->Passive), __box(request->KeepAlive), __box(request->Binary),
    request->Timeout == -1 ? S"none" : request->Timeout.ToString()
