    "Description": "Hi all,\n\nI am using the following code to zip a file. this is for mimetype of epub file. When i check the file in epub validator, it shows the error \"Mimetype file should contain only the string \"application/epub+zip\".\". So i checked the file using a hex editor and found the mimetype contains the following string. \n\"application/epub+zip..\"\nmoreover it should contains 20 byte length and my mimetype is 25 byte length. Additional 3 char at beginning and 2 char at end are added to my string.\nCan anyone help me to sort out this issue?\n\nusing (MemoryStream ms = new MemoryStream())\n            {\n                //content of the file is static and is used here directly\n                using (StreamWriter w = new StreamWriter(ms, Encoding.UTF8))\n                {\n                    w.WriteLine(\"application/epub+zip\");\n                }\n                using (ZipFile zip = new ZipFile())\n                {\n                    MemoryStream msMimetype = new MemoryStream(ms.ToArray());\n                    msMimetype.Seek(0, SeekOrigin.Begin);\n                   \n                    zip.Encryption = Ionic.Zip.EncryptionAlgorithm.None;\n                    zip.EmitTimesInUnixFormatWhenSaving = false;\n                    zip.EmitTimesInWindowsFormatWhenSaving = false;                    \n                    zip.UseZip64WhenSaving = Ionic.Zip.Zip64Option.Never;\n                    zip.CompressionMethod = Ionic.Zip.CompressionMethod.None;\n                    zip.CompressionLevel = Ionic.Zlib.CompressionLevel.None;\n                    \n                    zip.AddEntry(\"mimetype\", msMimetype);\n                  \n                  \n                    zip.Save(System.IO.Path.GetTempPath() + \"\\\\\" + FileName);\n                }\n}",
