Does the FtpWebResponse IDisposable close the response?

Question

I'm using the following code in my program, would I still need to call response.close()? Or does the FtpWebResponse IDisposable implementation close the response?

using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
{

}

So basically, would I need to do this?

using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
{
    response.close();
}

No you don't have to call Close, since Dispose already does that. FtpWebResponse is inherited from WebResponse and it has explicitly implemented Dispose, which internally call Close.

Code for WebResponse.cs from : http://www.dotnetframework.org/default.aspx/4@0/4@0/DEVDIV_TFS/Dev10/Releases/RTMRel/ndp/fx/src/Net/System/Net/WebResponse@cs/1305376/WebResponse@cs

 /// <internalonly>
        void IDisposable.Dispose() {
            try
            {
                Close();
                OnDispose();
            }
            catch { }
        }
