public override function BeginGetResponse ( callback : AsyncCallback, state : Object ) : IAsyncResult
An AsyncCallback delegate that references the method to invoke when the operation is complete.
A user-defined object that contains information about the operation. This object is passed to the callback delegate when the operation completes.
Return ValueAn IAsyncResult instance that indicates the status of the operation.
You must complete the asynchronous operation by calling the EndGetResponse method. Typically, EndGetResponse is called by the method referenced by callback. To determine the state of the operation, check the properties in the IAsyncResult object returned by the BeginGetResponse method.
If the Proxy property is set, either directly or in a configuration file, communications with the FTP server are made through the specified proxy.
BeginGetResponse does not block while waiting for the response from the server. To block, call the GetResponse method in place of BeginGetResponse.

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.
The following code example demonstrates ending an asynchronous operation to get a request's stream, and then starting a request to get the response. This code example is part of a larger example provided for the FtpWebRequest class overview.
