c# sharpcompress : How to check progress

IArchive rar = SharpCompress.Archive.Rar.RarArchive.Open(new FileInfo("ze.rar"), SharpCompress.Common.Options.None);
        rar.WriteToDirectory(Directory.GetCurrentDirectory() + "\\DATA", SharpCompress.Common.ExtractOptions.Overwrite);

With the above code i'm able to extract the rar file, however i would like to show the progress through the console. How can i check the progress?

Solution

  • This should provide a sample of how to calculate the current percentage of the extraction operation. Thanks to @MathiasRJessen for pointing out the behavior of IArchive.WriteToDirectory extension.

    IArchive rar = SharpCompress.Archive.Rar.RarArchive.Open(new FileInfo("ze.rar"), SharpCompress.Common.Options.None);
string directory = Path.Combine(Directory.GetCurrentDirectory(), "DATA");

// Calculate the total extraction size.
double totalSize = rar.Entries.Where(e => !e.IsDirectory).Sum(e => e.Size);
long completed = 0;

// Use the same logic for extracting each file like IArchive.WriteToDirectory extension.
foreach (var entry in rar.Entries.Where(e => !e.IsDirectory))
{
    entry.WriteToDirectory(directory, ExtractOptions.Overwrite);

    // Track each individual extraction.
    completed += entry.Size;
    var percentage = completed / totalSize;
    // TODO do something with percentage.
}
