之前都是想到用Process直接呼叫壓縮程式直接壓縮就好了
不過有印象還是有其他的方式
就找了一點人家寫的東東......
找到了下面這二個
DotNetZip ：http://www.codeplex.com/DotNetZip
我抓的時候是1.9版了.....裡面包了範例等等的東西
SharpZip ：http://www.icsharpcode.net/OpenSource/SharpZipLib/
直接DownLoadDLL應該就可以了不然裡面也是有範例程式
第一種方式如下：
protected void Button3_Click(object sender, EventArgs e)
{
MyZipFile();
//壓縮後直接下載檔案
FileStream fileStream = new FileStream("D:\\DotNetZip.zip", FileMode.Open);
long fileSize = fileStream.Length;
Response.ContentType = "application/zip";
Response.AddHeader("Content-Disposition", "attachment; filename=DotNetZip.zip");
Response.AddHeader("Content-Length", fileSize.ToString());
byte[] fileBuffer = new byte[fileSize];
fileStream.Read(fileBuffer, 0, (int)fileSize);
Response.BinaryWrite(fileBuffer);
Response.End();
}
//壓縮
private void MyZipFile()
{
string path = HttpContext.Current.Request.MapPath("Zip");
IEnumerable filelist = GetFiles(path);
var files = from f in filelist where f.Extension == ".bat" select f;
//DotNetZip壓縮輸出檔案
if (files.Count() > 0)
{
using (Ionic.Zip.ZipFile zip = new Ionic.Zip.ZipFile(System.Text.Encoding.Default))
{
zip.Password = "123456!";
foreach (var f in files)
{
zip.AddFile(f.FullName, "");
}
zip.Save("D:\\DotNetZip.zip");
zip.Dispose();
}
}
}
//取得檔案
private static IEnumerable GetFiles(string path)
{
string[] filenames = null;
List files = new List();
filenames = System.IO.Directory.GetFiles(path, "*.*", System.IO.SearchOption.AllDirectories);
foreach (string name in filenames)
{
files.Add(new System.IO.FileInfo(name));
}
return files;
}
//解壓縮
protected void Button4_Click(object sender, EventArgs e)
{
MyUnZipFile();
}
private void MyUnZipFile()
{
using (Ionic.Zip.ZipFile DotZip = Ionic.Zip.ZipFile.Read("D:\\DotNetZip.zip", System.Text.Encoding.Default))
{
DotZip.Password = "123456!";
DotZip.ExtractAll("D:\\");
}
}
第二種方式如下：
//取得專案路徑Zip目錄下所有含子目錄的檔案
private List GetFiles()
{
List lstFileInfo = new List();
string dir = Server.MapPath("Zip");
FileInfo info;
string[] files;
//取得dir下所有的檔案子目錄下的檔案
files = Directory.GetFiles(dir,"*.*",System.IO.SearchOption.AllDirectories);
foreach (string item in files)
{
info = new FileInfo(item);
//取得今天被寫入的檔案
//if (info.LastWriteTime.ToString("yyyyMMdd") == DateTime.Now.ToString("yyyyMMdd"))
//{
lstFileInfo.Add(info);
//}
}
return lstFileInfo;
}
//DotNetZip的壓縮方式
protected void btnDotNetZip_Click(object sender, EventArgs e)
{
//DotNetZip壓縮輸出檔案
List lstSelected = GetFiles();
if (lstSelected.Count > 0)
{
Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=" + "DotNetZip.zip");
using (Ionic.Zip.ZipFile zip = new Ionic.Zip.ZipFile(System.Text.Encoding.Default))
{
foreach (FileInfo file in lstSelected)
{
zip.AddFile(file.FullName, "");
}
zip.Save(Response.OutputStream);
zip.Dispose();
}
Response.End();
}
}
//SharpZip的壓縮方式
protected void btnSharpZip_Click(object sender, EventArgs e)
{
//SharpZip壓縮輸出檔案
List lstSelected = GetFiles();
if (lstSelected.Count > 0)
{
Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=" + "SharpZip.zip");
using (ICSharpCode.SharpZipLib.Zip.ZipOutputStream zip = new ICSharpCode.SharpZipLib.Zip.ZipOutputStream(Response.OutputStream))
{
foreach (FileInfo file in lstSelected)
{
AddZipEntry(zip,"", file.FullName);
}
zip.Finish();
zip.IsStreamOwner = false;// 避免 stream 被 zip 物件關閉
}
Response.End();
}
}
//SharpZip
private static void AddZipEntry(ICSharpCode.SharpZipLib.Zip.ZipOutputStream zip, string folder, string filename)
{
if (System.IO.Directory.Exists(filename) == true)
{
System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(filename);
string folder_ = folder + di.Name + "/";
ICSharpCode.SharpZipLib.Zip.ZipEntry zFolder = new ICSharpCode.SharpZipLib.Zip.ZipEntry(folder_);
zip.PutNextEntry(zFolder);
foreach (System.IO.DirectoryInfo d in di.GetDirectories())
AddZipEntry(zip, folder_, d.FullName);
foreach (System.IO.FileInfo f in di.GetFiles())
AddZipEntry(zip, folder_, f.FullName);
}
else if (System.IO.File.Exists(filename) == true)
{
// File
zip.SetLevel(9);
using (System.IO.FileStream fs = System.IO.File.OpenRead(filename))
{
byte[] b = new byte[fs.Length];
fs.Read(b, 0, b.Length);
ICSharpCode.SharpZipLib.Zip.ZipEntry z = new ICSharpCode.SharpZipLib.Zip.ZipEntry(folder + new System.IO.FileInfo(filename).Name);
zip.PutNextEntry(z);
zip.Write(b, 0, b.Length);
}
}
}
第三種方式如下：
protected void Button1_Click(object sender, EventArgs e)
{
//壓縮
ZipFiles("D:\\Zip","D:\\ICSharp.zip","12345");
//解壓縮
UnZipFiles("D:\\ICSharp.zip","D:\\","12345");
}
//壓縮
public static void ZipFiles(string FolderPath, string PathAndFile, string password)
{
//讀取檔案
ArrayList ar = GetFileList(FolderPath);
int TrimLength = (Directory.GetParent(FolderPath)).ToString().Length;
TrimLength += 1;
FileStream ostream;
byte[] obuffer;
ICSharpCode.SharpZipLib.Zip.ZipOutputStream oZipStream = new ICSharpCode.SharpZipLib.Zip.ZipOutputStream(File.Create(PathAndFile));
if (password != null && password != String.Empty)
oZipStream.Password = password;
oZipStream.SetLevel(9);
ICSharpCode.SharpZipLib.Zip.ZipEntry oZipEntry;
foreach (string Fil in ar)
{
oZipEntry = new ICSharpCode.SharpZipLib.Zip.ZipEntry(Fil.Remove(0, TrimLength));
oZipStream.PutNextEntry(oZipEntry);
if (!Fil.EndsWith(@"/"))
{
ostream = File.OpenRead(Fil);
obuffer = new byte[ostream.Length];
ostream.Read(obuffer, 0, obuffer.Length);
oZipStream.Write(obuffer, 0, obuffer.Length);
}
}
oZipStream.Finish();
oZipStream.Close();
}
//取得檔案(包含所有子目錄及子目錄下的檔案)
private static ArrayList GetFileList(string Dir)
{
ArrayList fils = new ArrayList();
bool Empty = true;
foreach (string file in Directory.GetFiles(Dir))
{
fils.Add(file);
Empty = false;
}
if (Empty)
{
if (Directory.GetDirectories(Dir).Length == 0)
fils.Add(Dir + @"/");
}
foreach (string dirs in Directory.GetDirectories(Dir))
{
foreach (object obj in GetFileList(dirs))
{
fils.Add(obj);
}
}
return fils;
}
//解壓縮
public static void UnZipFiles(string zipPathAndFile, string outputFolder, string password)
{
ICSharpCode.SharpZipLib.Zip.ZipInputStream s = new ICSharpCode.SharpZipLib.Zip.ZipInputStream(File.OpenRead(zipPathAndFile));
if (password != null && password != String.Empty)
s.Password = password;
ICSharpCode.SharpZipLib.Zip.ZipEntry theEntry;
string tmpEntry = String.Empty;
while ((theEntry = s.GetNextEntry()) != null)
{
string directoryName = outputFolder;
string fileName = Path.GetFileName(theEntry.Name);
if (directoryName != "")
{
Directory.CreateDirectory(directoryName);
}
if (fileName != String.Empty)
{
if (theEntry.Name.IndexOf(".ini") < 0)
{
string fullPath = directoryName + "\\" + theEntry.Name;
fullPath = fullPath.Replace("\\ ", "\\");
string fullDirPath = Path.GetDirectoryName(fullPath);
if (!Directory.Exists(fullDirPath)) Directory.CreateDirectory(fullDirPath);
FileStream streamWriter = File.Create(fullPath);
int size = 2048;
byte[] data = new byte[2048];
while (true)
{
size = s.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
streamWriter.Close();
}
}
}
s.Close();
}
