  NameDescription
Public methodCloseFrees the resources held by the response. (Overrides WebResponse.Close().)
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodDispose()Releases the unmanaged resources used by the WebResponse object. (Inherited from WebResponse.)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the WebResponse object, and optionally disposes of the managed resources. (Inherited from WebResponse.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodGetObjectDataInfrastructure. Populates a SerializationInfo with the data that is needed to serialize the target object. (Inherited from WebResponse.)
Public methodGetResponseStreamRetrieves the stream that contains response data sent from an FTP server. (Overrides WebResponse.GetResponseStream().)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)

Instances of FtpWebResponse are obtained by calling the GetResponse method. The returned object must be cast to an FtpWebResponse. When your application no longer needs the FtpWebResponse object, call the Close method to free the resources held by the FtpWebResponse.

The StatusCode property contains the status code returned by the server, and the StatusDescription property returns the status code and a message that describes the status. The values returned by these properties change as the messages are returned by the server.

Any data returned by the request, such as the list of file names returned for a ListDirectory request, is available in the stream returned by the GetResponseStream method. The length of the stream data can be obtained from the ContentLength property.

The following code example sends a request to delete a file on an FTP server and displays the status message from the server's response to the request. For additional examples, see the members of the WebRequestMethods.Ftp and FtpWebRequest classes.

public static bool DeleteFileOnServer(Uri serverUri)
{
    // The serverUri parameter should use the ftp:// scheme. 
    // It contains the name of the server file that is to be deleted. 
    // Example: ftp://contoso.com/someFile.txt. 
    //  

    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.DeleteFile;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();
    Console.WriteLine("Delete status: {0}",response.StatusDescription);  
    response.Close();
    return true;
}
