ZipArchiveEntry.Name 屬性

定義

取得 Zip 封存中的項目檔名。

public:
 property System::String ^ Name { System::String ^ get(); };
public string Name { get; }
member this.Name : string
Public ReadOnly Property Name As String

屬性值

Zip 封存中的項目檔名。

備註

屬性 Name 包含屬性的 FullName 部分,該部分會遵循最終目錄分隔符 (\) ,而且不包含子目錄階層。 例如,如果您使用 方法在 zip CreateEntryFromFile 封存中建立兩個專案,並提供 NewEntry.txt 作為第一個專案的名稱和第AddedFolder\\NewEntry.txt二個專案,這兩個專案都會在 屬性中NameNewEntry.txt 第一個專案也會在 屬性中FullNameNewEntry.txt但第二個項目在 屬性中FullName會有 AddedFolder\\NewEntry.txt

範例

下列範例示範如何從 zip 封存擷取專案,並評估項目的屬性。 它會使用 Name 屬性來顯示項目的名稱,以及 LengthCompressedLength 屬性來計算壓縮檔案的數目。

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

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string zipPath = @"c:\example\result.zip";

            using (ZipArchive archive = ZipFile.OpenRead(zipPath))
            {
                foreach (ZipArchiveEntry entry in archive.Entries)
                {
                    float compressedRatio = (float)entry.CompressedLength / entry.Length;
                    float reductionPercentage = 100 - (compressedRatio * 100);

                    Console.WriteLine (string.Format("File: {0}, Compressed {1:F2}%", entry.Name, reductionPercentage));
                }
            }
        }
    }
}
Imports System.IO
Imports System.IO.Compression

Module Module1

    Sub Main()
        Dim zipPath As String = "c:\example\result.zip"

        Using archive As ZipArchive = ZipFile.OpenRead(zipPath)
            For Each entry As ZipArchiveEntry In archive.Entries
                Dim compressedRatio As Single = entry.CompressedLength / entry.Length
                Dim reductionPercentage As Single = 100 - (compressedRatio * 100)

                Console.WriteLine(String.Format("File: {0}, Compressed {1:F2}%", entry.Name, reductionPercentage))
            Next
        End Using
    End Sub

End Module
