How do you know about the file in the archives, knowing the way? SevenZipSharp

[Burma]

Can we get the file in the archives somehow?

Like DotNetZip:

ZipFile zip = new ZipFile("1.zip");
long size = zip["dir\\file.txt"].UncompressedSize;

And you're sure that ZipFile They're not moving inside? It looks like the SevenZipSharp doesn't support this indexation, but nothing prevents you from changing the method. https://msdn.microsoft.com/ru-ru/library/bb535050(v=vs.110).aspx :

using System.Linq;
...
var extractor = new SevenZipExtractor("test.7z");
var size = extractor.ArchiveFileData.First(f => f.FileName == "dir\\file.txt").Size;

If you wish, you can write a method of expansion:

public static long GetFileSize(this SevenZipExtractor extractor, string fileName)
{
    return (long)extractor.ArchiveFileData.First(f => f.FileName == fileName).Size;
}
