FtpWebResponse.Close Method

Frees the resources held by the response.

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

public override void Close()

The Close method closes the data stream returned by the GetResponseStream method if the KeepAlive property is false. During the close, data might be sent to the server on the control connection.

NoteNote:

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

The following code example downloads data from a server, reads the data from the response stream, and then closes it.

public static bool DownloadFileFromServer(Uri serverUri, string localFileName)
{
    // The serverUri parameter should start with the ftp:// scheme. 
    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }
    // Get the object used to communicate with the server. 
    // Note that the cast to FtpWebRequest is done only 
    // for the purposes of illustration. If your application 
    // does not set any properties other than those defined in the 
    // System.Net.WebRequest class, you can use the following line instead: 
    // WebRequest request = WebRequest.Create(serverUri); 
    //
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.DownloadFile;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();
