FtpWebRequest.ServicePoint Property

Gets the ServicePoint object used to connect to the FTP server.

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

public ServicePoint ServicePoint { get; }
/** @property */
public ServicePoint get_ServicePoint ()

public function get ServicePoint () : ServicePoint

Not applicable.

Property Value

A ServicePoint object that can be used to customize connection behavior.

If no ServicePoint object exists, one is created for the FTP server. To set the maximum number of connections that can be open for an FTP server, set the ConnectionLimit property of the ServicePoint instance returned by this property.

The following code example retrieves the service point from a request and sets the maximum number of connections to one.

public static bool ListFilesOnServer(Uri serverUri)
{
    // The serverUri should start with the ftp:// scheme.
    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }
    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.ListDirectory;
    
    // Get the ServicePoint object used for this request, and limit it to one connection.
    // In a real-world application you might use the default number of connections (2),
    // or select a value that works best for your application.
    
    ServicePoint sp = request.ServicePoint;
    Console.WriteLine("ServicePoint connections = {0}.", sp.ConnectionLimit);
    sp.ConnectionLimit = 1;
    
    FtpWebResponse response = (FtpWebResponse) request.GetResponse();
     
    // The following streams are used to read the data returned from the server.
    Stream responseStream = null;
    StreamReader readStream = null;
    try
    {
        responseStream = response.GetResponseStream(); 
        readStream = new StreamReader(responseStream, System.Text.Encoding.UTF8);
 
        if (readStream != null)
        {
            // Display the data received from the server.
            Console.WriteLine(readStream.ReadToEnd());
        } 
        Console.WriteLine("List status: {0}",response.StatusDescription);            
    }
    finally
    {
        if (readStream != null)
        {
            readStream.Close();
        }
        if (response != null)
        {
            response.Close();
        }
    }
   
    return true;
}
