.Net Zip Up文件
什么是使用C＃压缩文件的最佳方法？ 理想情况下，我希望能够将文件分成单个存档。
您可以使用DotNetZip来实现这一目标。 它可以在任何应用程序中自由使用。
这是一些示例代码：
try { // for easy disposal using (ZipFile zip = new ZipFile()) { // add this map file into the "images" directory in the zip archive zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images"); // add the report into a different directory in the archive zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files"); zip.AddFile("ReadMe.txt"); zip.Save("MyZipFile.zip"); } } catch (System.Exception ex1) { System.Console.Error.WriteLine("exception: " + ex1); } 如果你有4.5+版本，现在已经内置到框架中
否则，使用Ionic。
名称空间是System.IO.Packaging.ZIPPackage 。

你看过SharpZipLib了吗？
我相信你可以使用System.IO.Packaging命名空间中的类来构建zip文件 – 但每次我试图调查它时，我发现它相当令人困惑……
看看这个库： http ： //www.icsharpcode.net/OpenSource/SharpZipLib/
它非常全面，它涉及多种格式，是开源的，您可以在闭源商业应用程序中使用。
它使用起来非常简单：
byte[] data1 = new byte[...]; byte[] data2 = new byte[...]; /*...*/ var path = @"c:\test.zip"; var zip = new ZipOutputStream(new FileStream(path, FileMode.Create)) { IsStreamOwner = true } zip.PutNextEntry("File1.txt"); zip.Write(data1, 0, data1.Length); zip.PutNextEntry("File2.txt"); zip.Write(data2, 0, data2.Length); zip.Close(); zip.Dispose();
有几个图书馆 – 最受欢迎的是DotNetZip和SharpZipLib 。
嗨我用ShapLib库创建了两个方法（你可以在这里下载http://www.icsharpcode.net/opensource/sharpziplib/ ）想要分享，它们很容易使用只需传递源和目标路径（完整路径）包括文件夹/文件和扩展名）。 希望对你有所帮助！
