ZipArchiveEntry.Name Property

.NET Framework (current version)
 

Gets the file name of the entry in the zip archive.

Namespace:   System.IO.Compression
Assembly:  System.IO.Compression (in System.IO.Compression.dll)

public string Name { get; }

Property Value

Type: System.String

The file name of the entry in the zip archive.

The Name property contains the portion of the FullName property that follows the final directory separator character (\), and does not include the subdirectory hierarchy. For example, if you create two entries in a zip archive by using the CreateEntryFromFile method and provide NewEntry.txt as the name for the first entry and AddedFolder\\NewEntry.txt for the second entry, both entries will have NewEntry.txt in the Name property. The first entry will also have NewEntry.txt in the FullName property, but the second entry will have AddedFolder\\NewEntry.txt in the FullName property.

The following example shows how to retrieve entries from a zip archive and evaluate the properties of the entries. It uses the Name property to display the name of the entry, and the Length and CompressedLength properties to calculate how much the file was compressed.

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)); 
                }
            } 
        }
    }
}
