Saving Attachments thru WebDav

[Michael OC]

Hi,

I have a somewhat working solution that will go into the mailbox and get the attachments and save them to a folder.

My issue is that sometimes it works fine, while others it gives me a 404 error.

As I debug the solution I can see that the app. can see the emails and the attachments, but then will 404 error out. Here is code for DownloadSingleA ttachment().

HttpWebRequest WebReq;
WebReq = (HttpWebRequest)WebRequest.Create(emlURL + "/" + filename);

        try
        {
            if (this.myCred.UserName.Length != 0)
            {
                // Use Basic Authentication
                CredentialCache myCredentialCache = new  CredentialCache();
                myCredentialCache.Add(new System.Uri(emlURL), "NTLM", myCred);
                WebReq.Credentials = myCredentialCache;
            }
            else
            {
                // Use Windows Authentication
                WebReq.Credentials = CredentialCache.DefaultCredentials;
            }

            //Add the headers
            WebReq.Headers.Add("Translate", "f");
            WebReq.KeepAlive = true;
            WebReq.AllowAutoRedirect = false;
            WebReq.Method = "GET";

            // Get the response for our request
            HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();

switch (WebResp.ContentType)
{
   case "application/octet-stream":
                    Stream tmpStream = WebResp.GetResponseStream();

                    FileStream file = new FileStream(path + "\\" + newFilename, System.IO.FileMode.Create, FileAccess.ReadWrite, FileShare.None, 4096, false);

                    byte[] buffer = new byte[4096];
                    int length;
                    length = tmpStream.Read(buffer, 0, 4096);

                    while (length > 0)
                    {
                        file.Write(buffer, 0, length);
                        length = tmpStream.Read(buffer, 0, 4096);
                    }

                    file.Close();
                    tmpStream.Close();
                    break;
}
