Actually you can use the ZipFileclass in .NET 4.0 as well. You just gotta add a reference to the System.IO.Compression.FileSystem.dllfile, located in:
实际上，您也可以ZipFile在 .NET 4.0 中使用该类。您只需添加对System.IO.Compression.FileSystem.dll文件的引用，该文件位于：
%SystemRoot%\Microsoft.NET\assembly\GAC_MSIL\System.IO.Compr??????ession.FileSyste??m\??v4??.0_4.0.0.0__??b77a??5c56??1934e089??\Syste??m.IO.C??ompr??ession.F??ileSyste????m.dll
As you see it is located in the "v4.0" folder, so it exists in .NET 4.0, but for some reason isn't referenced automatically.
如您所见，它位于“v4.0”文件夹中，因此它存在于 .NET 4.0 中，但由于某种原因未自动引用。
