Adapted from the ZipArchive and XmlSerializer.Deserialize() manual pages.

ZipArchiveEntry类具有Open()方法，该方法将流返回到文件.

The ZipArchiveEntry class has an Open() method, which returns a stream to the file.

string zipPath = @"c:\example\start.zip";

using (ZipArchive archive = ZipFile.OpenRead(zipPath))
{
    var sample = archive.GetEntry("sample.xml");
    if (sample != null)
    {
        using (var zipEntryStream = sample.Open())
        {               
            XmlSerializer serializer = new XmlSerializer(typeof(SampleClass));  

            SampleClass deserialized = 
                (SampleClass)serializer.Deserialize(zipEntryStream);
        }
    }
} 

请注意，正如MSDN上记录的那样，您需要添加对.NET程序集System.IO.Compression.FileSystem的引用才能使用ZipFile类.

Note that, as documented on MSDN, you need to add a reference to the .NET assembly System.IO.Compression.FileSystem in order to use the ZipFile class.
