https://bugzilla.novell.com/show_bug.cgi?id=668494#c0 Summary: System.Io.Compression.DeflateStream not working Classification: Mono Product: MonoTouch Version: unspecified Platform: x86 OS/Version: Apple iOS 4.2 Status: NEW Severity: Normal Priority: P5 - None Component: Class Libraries AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- I am using the DeflateStream object to compress a stream. The stream is a Serialized XML object. When I use the GzipStream object it works perfectly. When I switch to a DeflateStream object the output file is zero bytes long. Unfortunately I need to use the Deflate format to support integration to a legacy system. Here is some sample code that produces the 0 byte file. The .dat file will be 0 bytes while the .zip file is 4KB. I have run this on the iOS simulator and the iPhone directly. Same problem. Thanks for your help. TestRoot t; XmlSerializer ser = new XmlSerializer( typeof( TestRoot )); string sZipFileName = Path.Combine( Environment.GetFolderPath (Environment.SpecialFolder.Personal), "test.zip" ); string sDatFileName = Path.Combine( Environment.GetFolderPath (Environment.SpecialFolder.Personal), "test.dat" ); if( File.Exists( sZipFileName )) File.Delete( sZipFileName ); if( File.Exists( sDatFileName )) File.Delete( sDatFileName ); t = new TestRoot (); FileStream fsZipFile = new FileStream( sZipFileName, FileMode.Create ); FileStream fsDatFile = new FileStream( sDatFileName, FileMode.Create ); GZipStream gZipStream = new GZipStream( fsZipFile, CompressionMode.Compress ); DeflateStream deflateStream = new DeflateStream( fsDatFile, CompressionMode.Compress ); ser.Serialize( gZipStream, t); ser.Serialize( deflateStream, t); fsZipFile.Flush(); fsDatFile.Flush(); fsZipFile.Flush(); fsDatFile.Flush(); [Serializable] public class TestRoot { public List<TestClass> Test { get; set; } public TestRoot() { Test = new List<TestClass>(); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); Test.Add( new TestClass( "dfasd", "asdf", "safag" )); } } [Serializable] public class TestClass { public string A { get; set; } public string B { get; set; } public string C { get; set; } public TestClass() { } public TestClass( string a, string b, string c) { A =a; B = b; C = c; } } -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
