Hallo zusammen!
Ich benutze Microsoft Visual Studio und programmiere in C++. Mit der GZipSteam Klasse kann ich eine einzelne Datei zippen. Wie kann ich einen Verzeichnisbaum zippen?? Bitte detaillierte Antworten, da ich noch recht neu beim programmieren bin. Hier der code:
void GZipCompressDecompress( String^ filename )
{
Console::WriteLine( "Test compression and decompression on file {0}", filename );
FileStream^ infile;
try
{
// Open the file as a FileStream object.
infile = gcnew FileStream( filename,FileMode::Open,FileAccess::Read,FileShare::Read );
array<Byte>^buffer = gcnew array<Byte>((int)infile->Length);
// Read the file to ensure it is readable.
int count = infile->Read( buffer, 0, buffer->Length );
if ( count != buffer->Length )
{
infile->Close();
Console::WriteLine( "Test Failed: Unable to read data from file" );
return;
}
infile->Close();
//MemoryStream^ ms = gcnew MemoryStream;
FileStream^ fs = gcnew FileStream("C \temp\\test.gz,FileMode::Create,FileAccess::Write);
// Use the newly created memory stream for the compressed data.
GZipStream ^ compressedzipStream = gcnew GZipStream( fs,CompressionMode::Compress,true );
Console::WriteLine( "Compression" );
compressedzipStream->Write( buffer, 0, buffer->Length );
// Close the stream.
compressedzipStream->Close();
Console::WriteLine( "Original size: {0}, Compressed size: {1}", buffer->Length, fs->Length );
Vielen Dank im Voraus!! |
