        using (SPWeb oWeb = oSite.OpenWeb())
        {
            SPList oList = oWeb.Lists[listName];

            SPListItemCollection oListItems = oList.Items;
            foreach (SPListItem item in oListItems)
            {
                SPAttachmentCollection attachmentscol= item.Attachments;

                if (attachmentscol.Count <= 0) return string.Empty;

                foreach (var attachment in attachmentscol)
                {
                    strAttachNames.Append(attachment.ToString());

            SPFolder cols = web.Folders[site.Url + "/TestDocumentLib"];

            SPList list = web.Lists["TestDocumentLib"];

            SPDocumentLibrary docLibrary = (SPDocumentLibrary)list;

            SPListItem listItem = docLibrary.GetItemById(properties.ListItemId);

            SPFile file1 = web.GetFile(listItem.UniqueId);

            string strUrl = file1.ServerRelativeUrl.ToString();

            string destinationFolderUrl = @"C:\Documents and Settings\Documents\";

            byte[] binfile = file1.OpenBinary();

            string strRootUrl = list.RootFolder.ServerRelativeUrl.ToString();

            int count = strUrl.Split('/').Length - 1;

            string[] str = strUrl.Split('/');

            for (int i = 1; i < count; i++)

            {

                destinationFolderUrl += str[i] + "\\" + folderName;

            }

            SPSecurity.RunWithElevatedPrivileges(delegate()

           {

               if (!(Directory.Exists(destinationFolderUrl)))

               {

                   Directory.CreateDirectory(destinationFolderUrl);

                   FileStream fstream = System.IO.File.Create(destinationFolderUrl + "\\" + file1.Name);

                   fstream.Write(binfile, 0, binfile.Length);

                   fstream.Close();

               }

               else

               {

                   //Directory.CreateDirectory(destinationFolderUrl);

                   FileStream fstream = System.IO.File.Create(destinationFolderUrl + "\\" + file1.Name);

                   fstream.Write(binfile, 0, binfile.Length);

                   fstream.Close();
