Zip complete folder using System.IO.Compression
提问by user3062805
I have one example where all the files in the folder are zipped but not the folder itself .[This code is from MSDN]
我有一个示例，其中文件夹中的所有文件都被压缩，但文件夹本身没有被压缩。[此代码来自 MSDN]
using System;
using System.IO;
using System.IO.Compression;
namespace zip
{
public class Program
{
public static void Main()
{
string directoryPath = @"c ------------------------------------------------------------------------ :\users\public\reports";
DirectoryInfo directorySelected = new DirectoryInfo(directoryPath);
foreach (FileInfo fileToCompress in directorySelected.GetFiles())
{
Compress(fileToCompress);
}
foreach (FileInfo fileToDecompress in directorySelected.GetFiles("*.gz"))
{
Decompress(fileToDecompress);
}
}
public static void Compress(FileInfo fileToCompress)
{
using (FileStream originalFileStream = fileToCompress.OpenRead())
{
if ((File.GetAttributes(fileToCompress.FullName) & FileAttributes.Hidden) != FileAttributes.Hidden & fileToCompress.Extension != ".gz")
{
using
(FileStream compressedFileStream = File.Create(fileToCompress.FullName + ".gz"))
{
using (GZipStream compressionStream = new GZipStream(compressedFileStream, CompressionMode.Compress))
{
originalFileStream.CopyTo(compressionStream);
Console.WriteLine("Compressed {0} from {1} to {2} bytes.", fileToCompress.Name, fileToCompress.Length.ToString(), compressedFileStream.Length.ToString());
}
}
}
}
}
public static void Decompress(FileInfo fileToDecompress)
{
using (FileStream originalFileStream = fileToDecompress.OpenRead())
{
string currentFileName = fileToDecompress.FullName;
string newFileName = currentFileName.Remove(currentFileName.Length - fileToDecompress.Extension.Length);
using (FileStream decompressedFileStream = File.Create(newFileName))
{
using (GZipStream decompressionStream = new GZipStream(originalFileStream, CompressionMode.Decompress))
{
decompressionStream.CopyTo(decompressedFileStream);
Console.WriteLine("Decompressed: {0}", fileToDecompress.Name);
}
}
}
}
}
}

I don't think you can zip a complete folder using System.IO.Compression, you can only compress files inside the folder. You can use DotNetZip instead. It is a 100% managed code library that can be used in any .NET application - Console, Winforms, WPF, ASP.NET, Sharepoint, Web services apps, and so on.
我不认为你可以使用 System.IO.Compression 压缩一个完整的文件夹，你只能压缩文件夹内的文件。您可以改用 DotNetZip。它是一个 100% 托管代码库，可用于任何 .NET 应用程序 - 控制台、Winforms、WPF、ASP.NET、Sharepoint、Web 服务应用程序等。
Download developer's kit package from http://dotnetzip.codeplex.com/Release/ProjectReleases.aspx.
从http://dotnetzip.codeplex.com/Release/ProjectReleases.aspx下载开发人员工具包包。
Reference necessaries including DotNetZip DLL in your application and do follows:
在您的应用程序中引用必需品，包括 DotNetZip DLL，并执行以下操作：
string[] MainDirs = Directory.GetDirectories(""c:\users\public\reports");
for (int i = 0; i < MainDirs.Length; i++)
{
using (ZipFile zip = new ZipFile())
{
zip.UseUnicodeAsNecessary = true;
zip.AddDirectory(MainDirs[i]);
zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression;
zip.Comment = "This zip was created at " + System.DateTime.Now.ToString("G");
zip.Save(string.Format("test{0}.zip", i));
}
}
Hope this helps, Thanks
希望这有帮助，谢谢
