hello,


i use the following method:



public static void zip(string targetFileName, Dictionary<string, string> dictFilesToZip, string action)

{



            #region zip

            Zip zip = new Zip();

            if (action.Equals("append"))

            {

                zip.Open(targetFileName, FileMode.Open);

            }

            else

            {

                zip.Create(targetFileName);

            }



            //TransferOptions opt = new TransferOptions();

            //opt.FileExistsResolveAction = FileExistsResolveAction.OverwriteAll;




            zip.BeginUpdate();

            try

            {

                foreach (KeyValuePair<String, String> entry in dictFilesToZip)

                {

                    //string path_to_file = Path.GetDirectoryName(entry.Key);

                    //string filename = Path.GetFileName(entry.Key);

                    //string[] file = new string[1];

                    //file[0] = filename;

                    //zip.AddFile()

                    //zip.AddFiles(path_to_file, file, Path.GetDirectoryName(entry.Value).Replace(Path.DirectorySeparatorChar.ToString(), "/"), opt);



                    string strTargetFile = entry.Value.Replace(Path.DirectorySeparatorChar.ToString(), "/");

                    if (zip.FileExists(strTargetFile))

                        zip.DeleteFile(strTargetFile);



                    zip.AddFile(entry.Key, strTargetFile);

                }

            }

            catch (Exception ex)

            {

                zip.CancelUpdate();

                throw ex;

            }

            finally

            {

                zip.EndUpdate();

                zip.Close();

            }

            #endregion

        }



Calling:



string targetFileName = @"e:\DEV\DotNet\zipper\TestFiles\e0745045-54cf-45bb-a714-2d72c906a865_FRA_00_J00002314.ppf";

                Dictionary<string, string> dictFilesToZip = new Dictionary<string, string>();

                dictFilesToZip.Add(@"e:\DEV\DotNet\zipper\TestFiles\FuzzyTest_doc.doc", @"ORG\orig_FuzzyTest_doc.doc");

                dictFilesToZip.Add(@"e:\DEV\DotNet\zipper\TestFiles\FuzzyTest_doc2.doc", @"ORG\orig_FuzzyTest_doc2.doc");



                string action = "append"; // TODO: Initialize to an appropriate value



                ZipHelper.zip(targetFileName, dictFilesToZip, action);



My Problem is at the zip.EndUpdate();. I get the error that a closed zip could not be closed.



Before I used the commeted Code, with this it works fine. It also works if i remove the begin, end update thing?!?



Thanks for your help
