I have a HttpWebRequest that is currently downloading the file  but I want to stop it downloading and save the file in a folder instead. 
webRequest.Method = "GET";
webRequest.Credentials = CredentialCache.DefaultCredentials;
webRequest.ContentType = "text/xml;charset=UTF-8";
using (var webResponse = webRequest.GetResponse())
using (var webStream = webResponse.GetResponseStream())
{
    if (webStream != null)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/pdf";
        Response.AddHeader("Content-Disposition", "attachment; filename=\"test.pdf\"");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        webStream.CopyTo(Response.OutputStream);
        Response.Flush();
        Response.End();
    }
}
I have tried changing the ContactType to Response.ContentType = "application/x-download"; and adding Response.TransmitFile but the file still downloads.
