Hi, I need set a file name internal of gzip.
I re-compiler ICSharpCode.SharpZipLib.csproj
I modifided a class GZipOutputStream
Create a new method
private string _fname = "";
/// <summary>
/// Sets the name of internal file of gzip
/// Create by Afonso Dutra
/// </summary>
/// <param name="name">name of internal file in de gzip</param>
public void SetFileName(string name)
{
_fname = name;
}
And I modifided a exist method WriteHeader()
//AFONSO
byte[ fname = { 0 };
if (!string.IsNullOrEmpty(_fname))
{
fname = Encoding.GetEncoding("ISO-8859-1").GetBytes(_fname);
Array.Resize<byte>(ref fname, fname.Length + 1);
fname[fname.Length - 1] = 0;
}
//END AFONSO
And modifided de byte of Header
byte[ gzipHeader = {
// The two magic bytes
(byte) (GZipConstants.GZIP_MAGIC >> 8),
(byte) (GZipConstants.GZIP_MAGIC & 0xff),
// The compression type
(byte) Deflater.DEFLATED,
// The flags (not set)
(byte) (!string.IsNullOrEmpty(_fname) ? GZipConstants.FNAME : 0),
// The modification time
(byte) mod_time,
(byte) (mod_time >> 8),
(byte) (mod_time >> 16),
(byte) (mod_time >> 24),
// The extra flags
0,
// 255 The OS type (unknown)
// 0 FAT filesystem (MS-DOS, OS/2, NT/Win32)
(byte) 0 //255
};
For incluide a real file name in gzip, include is function after "baseOutputStream_.Write(gzipHeader, 0, gzipHeader.Length);"
//AFONSO
if (!string.IsNullOrEmpty(_fname))
baseOutputStream_.Write(fname, 0, fname.Length);
//END AFONSO
It´s possible incluide this code for future release?
Thanks.
