.NET

Volevo farne uno script ma mi sembrava troppo lungo, ma troppo corto per un articolo, insomma non sapevo dove metterlo e alla fine ho deciso di piazzarlo qui, in caso il boss mi dirà.

Cmq sono un'insieme di metodi che comprimono una cartella e tutto il suo contenuto in un unico file zip mantenendo la struttura.

public static void ZipFolder(string path, string path2Save, string name, bool recursive) 
{ 
Crc32 crc = new Crc32(); if (String.IsNullOrEmpty(name)) 
name = new DirectoryInfo(path).Name; if (!name.EndsWith(".zip")) 
name += ".zip" if (!Directory.Exists(path2Save)) 
Directory.CreateDirectory(path2Save); try 
{ 
using (ZipOutputStream s = new ZipOutputStream(File.Create(path2Save + name))) 
{ 
s.SetLevel(6); 
string basepath = path.Replace(new DirectoryInfo(path).Name, String.Empty); if (basepath.EndsWith("\\\\")) 
basepath = basepath.Replace("\\\\", "\\"); 
AddToZip(path, s, crc, basepath, recursive); s.Finish(); 
s.Close(); 
} 
} 
catch (Exception e) 
{ 
File.Delete(path2Save + name); 
throw e; 
} 
} 
 private static void AddToZip(string path, ZipOutputStream s, Crc32 crc, string basepath, bool recursive) 
{ 
foreach (string srcFileName in Directory.GetFiles(path)) 
{ 
string filepath = path + @"\" + new DirectoryInfo(srcFileName).Name; 
AddFile(s, filepath, crc, basepath); 
} foreach (string strSrcSubDirectory in Directory.GetDirectories(path)) 
AddFolder(s, strSrcSubDirectory, crc, basepath); if (recursive) 
foreach (string strSrcSubDirectory in Directory.GetDirectories(path)) 
{ 
path += @"\" + new DirectoryInfo(strSrcSubDirectory).Name; 
AddToZip(strSrcSubDirectory, s, crc, basepath, recursive); 
} 
} private static void AddFile(ZipOutputStream s, string file, Crc32 crc, string basepath) 
{ 
using (FileStream fs = File.OpenRead(file)) 
{ 
byte[] buffer = new byte[fs.Length]; 
fs.Read(buffer, 0, buffer.Length); ZipEntry entry; if (string.IsNullOrEmpty(basepath)) 
entry = new ZipEntry(file.Replace(basepath, String.Empty).ToLower()); 
else 
entry = new ZipEntry(file); entry.DateTime = DateTime.Now; 
entry.Size = fs.Length; crc.Reset(); 
crc.Update(buffer); entry.Crc = crc.Value; 
s.PutNextEntry(entry); 
s.Write(buffer, 0, buffer.Length); 
} 
} private static void AddFolder(ZipOutputStream s, string file, Crc32 crc, string basepath) 
{ 
ZipEntry entry; if (string.IsNullOrEmpty(basepath)) 
entry = new ZipEntry(file.Replace(basepath, String.Empty).ToLower()); 
else 
entry = new ZipEntry(file); entry.DateTime = DateTime.Now; crc.Reset(); entry.Crc = crc.Value; 
s.PutNextEntry(entry); 
}

Va sistemata un po, per gestire bene le eccezzioni e perchè l'ho solo provata al volo ma sicuramente il codice può essere ottimiccato, però in linea di massima funziona
