Esempio

Nell'esempio seguente viene illustrato come aprire un archivio zip e eseguire l'iterazione tramite la raccolta di voci.

using System;
using System.IO;
using System.IO.Compression;

class Program

    {
        string zipPath = @".\result.zip";

        string extractPath = Console.ReadLine();

        // Normalizes the path.
        extractPath = Path.GetFullPath(extractPath);

        // Ensures that the last character on the extraction path
        // is the directory separator char.
        // Without this, a malicious zip file could try to traverse outside of the expected
        // extraction path.
        if (!extractPath.EndsWith(Path.DirectorySeparatorChar.ToString(), StringComparison.Ordinal))
            extractPath += Path.DirectorySeparatorChar;

                    string destinationPath = Path.GetFullPath(Path.Combine(extractPath, entry.FullName));
