Upload File from a networkdrive into a Sharepoint Library

Last week I wrote some code for migrating a networkdrive folder content into a SharePoint Library. 
You cannot use the Lists.asmx for uploading the documents because this webservice does not provide
the functionality for uploading files. 
But after a little bit of research I found quickly that you can use the copy.asmx webservice. 
Normally it is used for copying files between two SharePoint Libraries but it also 
work for copying files from a networkdrive into a SharePoint Library.

So you can use the code behind for copying a file on a network drive in a Sharepoint Library.

        SPCopyService.Copy copy = new SPCopyService.Copy();
  copy.Url = sSiteUrl + "/_vti_bin/copy.asmx";
        try
        {
            if (bDefaultLogon)
                copy.Credentials = System.Net.CredentialCache.DefaultCredentials;
            else
            {
                copy.PreAuthenticate = true;
                copy.Credentials = new System.Net.NetworkCredential(sTechnicalUserID, sTechnicalUserPW, sTechnicalUserDomain);
            }

            string destinationUrl = sSharePointDestinationFolder + "/" + sfilename;
            // destinationUrl = SiteUrl + "/" + SiteLibrary + "/" + OptionalFolder + "/" + filename.Extention
            string[] destinationUrls = { destinationUrl };
            SPCopyService.FieldInformation info1 = new SPCopyService.FieldInformation();
            info1.DisplayName = sfilename;
            info1.InternalName = replaceSpecialChars(sfilename);
            info1.Type = SPCopyService.FieldType.Text;
            info1.Value = replaceSpecialChars(sfilename);
            SPCopyService.FieldInformation[] info = { info1 };
            SPCopyService.CopyResult copyResult = new SPCopyService.CopyResult();
            SPCopyService.CopyResult[] copyResults = { copyResult };
            //Reading the document contents in to stream
            FileStream strm = new FileStream(sFilePath + @"\" + sfilename, FileMode.Open, FileAccess.Read);
            byte[] fileContents = new Byte[strm.Length];
            byte[] r = new Byte[strm.Length];
            int ia = strm.Read(fileContents, 0, Convert.ToInt32(strm.Length));
            strm.Close();
            // call the webservice procedure CopyIntoItems       
            uint result = copy.CopyIntoItems(sfilename, destinationUrls, info, fileContents, out copyResults);
            // Check for Errors:     
            foreach (SPCopyService.CopyResult copyRes in copyResults)
            {
                string msg =  "====================================" +
                "\n " + "SharePoint Error:" +
                "\n " + "              Url: " + copyRes.DestinationUrl +
                "\n " + "              Error Code: " + copyRes.ErrorCode +
                "\n " + "              Message: " + copyRes.ErrorMessage +
                "\n " + "====================================";
                if (copyRes.ErrorCode.ToString().Equals("Success"))
                {
                    // code for success if needed...
                }
                else
                {
                    // code for a failure if needed...
                }
                Console.WriteLine(msg);
            }
        }
        catch (Exception e)
        {
            iFailedUpdatedRecords++;
            Console.WriteLine("   Error on upload...");
        }
        finally {
            copy.Dispose();
        }
