FtpWebRequest.EndGetResponse Method

If the operation has not completed at the time the EndGetResponse method is called, EndGetResponse blocks until the operation completes. To prevent blocking, check the IsCompleted property before calling EndGetResponse.

In addition to the exceptions noted in "Exceptions," EndGetResponse rethrows exceptions that were thrown while communicating with the server.

The following code example demonstrates ending an asynchronous operation to get a response. This code example is part of a larger example provided for the FtpWebRequest class overview.

// The EndGetResponseCallback method   
// completes a call to BeginGetResponse. 
private static void EndGetResponseCallback(IAsyncResult ar)
{
    FtpState state = (FtpState) ar.AsyncState;
    FtpWebResponse response = null;
    try 
    {
        response = (FtpWebResponse) state.Request.EndGetResponse(ar);
        response.Close();
        state.StatusDescription = response.StatusDescription;
        // Signal the main application thread that  
        // the operation is complete.
        state.OperationComplete.Set();
    }
    // Return exceptions to the main application thread. 
    catch (Exception e)
    {
        Console.WriteLine ("Error getting response.");
        state.OperationException = e;
        state.OperationComplete.Set();
    }
}
