    "Description": "I found a problem concerning the extraction of an archive using the Extract method of the ZipEntry class. I passed the argument extractExistingFile at the Extract method\n with the value InvokeExtractProgressEvent in order to popup a window asking the user whether he wants overwrite the file. Whatever the delegate retrieves from the Cancel property, a ZipException is throw with the message \"The file already exists\". This is not the expected behaviour.\n \nThis is an excerpt of my test program:\nMain function\n              using (ZipFile zip = ZipFile.Read(buffer))\n                {\n                    zip.ExtractProgress += new EventHandler<ExtractProgressEventArgs>(zip_ExtractProgress);\n                    foreach (ZipEntry entry in zip.Entries)\n                    {\n                        if (entry.IsDirectory)\n                            continue;\n                        index = entry.FileName.LastIndexOf('/');\n                        if (index > 0)\n                        {\n                            filename = entry.FileName.Substring(index + 1);\n                            entry.FileName = filename;\n                        }\n                        else\n                            filename = entry.FileName;\n                        entry.Extract(outputPath,ExtractExistingFileAction.InvokeExtractProgressEvent);\n                    }\n                }\n \n[..]\n                void zip_ExtractProgress(object sender, ExtractProgressEventArgs e)\n         {\n            if (e.EventType == ZipProgressEventType.Extracting_ExtractEntryWouldOverwrite)\n            {\n                ZipEntry entry = e.CurrentEntry;\n                ExctractionCancelationEventArgs args = new ExctractionCancelationEventArgs(e.CurrentEntry.FileName, e.Cancel);\n                if (ExtractionWouldOverwrite != null)\n                {\n                    //Custom event which retrieve from the user whether he wants overwrite the file or not\n                    ExtractionWouldOverwrite(this, args);\n                    e.Cancel = args.Cancel;\n \n                    //Code I have added to solve the issue\n                    if (!e.Cancel)\n                        entry.ExtractExistingFile = ExtractExistingFileAction.OverwriteSilently;\n                    else\n                        entry.ExtractExistingFile = ExtractExistingFileAction.DontOverwrite;\n                }\n            }\n           }\n \nBy the way, this is a great library. Good job.\n \nRegards\n \nJérémie",
