public:
 property System::Collections::ObjectModel::ReadOnlyCollection<System::IO::Compression::ZipArchiveEntry ^> ^ Entries { System::Collections::ObjectModel::ReadOnlyCollection<System::IO::Compression::ZipArchiveEntry ^> ^ get(); };
public System.Collections.ObjectModel.ReadOnlyCollection<System.IO.Compression.ZipArchiveEntry> Entries { get; }
member this.Entries : System.Collections.ObjectModel.ReadOnlyCollection<System.IO.Compression.ZipArchiveEntry>
Public ReadOnly Property Entries As ReadOnlyCollection(Of ZipArchiveEntry)

プロパティ値

現在 zip アーカイブ内にあるエントリのコレクション。The collection of entries that are currently in the zip archive.

例外

zip アーカイブは読み取りをサポートしません。The zip archive does not support reading.

zip アーカイブが破棄されました。The zip archive has been disposed.

zip アーカイブが破損しているため、エントリを取得できません。The zip archive is corrupt, and its entries cannot be retrieved.

次の例は、zip アーカイブを開き、エントリのコレクションを反復処理する方法を示しています。The following example shows how to open a zip archive and iterate through the collection of entries.

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

class Program
{
    static void Main(string[] args)
    {
        string zipPath = @".\result.zip";

        Console.WriteLine("Provide path where to extract the zip file:");
        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;

        using (ZipArchive archive = ZipFile.OpenRead(zipPath))
        {
            foreach (ZipArchiveEntry entry in archive.Entries)
            {
                if (entry.FullName.EndsWith(".txt", StringComparison.OrdinalIgnoreCase))
                {
                    // Gets the full path to ensure that relative segments are removed.
                    string destinationPath = Path.GetFullPath(Path.Combine(extractPath, entry.FullName));

                    // Ordinal match is safest, case-sensitive volumes can be mounted within volumes that
                    // are case-insensitive.
                    if (destinationPath.StartsWith(extractPath, StringComparison.Ordinal))
                        entry.ExtractToFile(destinationPath);
                }
            }
        }
    }
}

注釈

Entriesプロパティを使用して、エントリのコレクション全体を取得します。Use the Entries property to retrieve the entire collection of entries. 名前でGetEntry 1 つのエントリを取得するには、メソッドを使用します。Use the GetEntry method to retrieve a single entry by name.
