How to handle unzipping ZipFile with paths that are too long/duplicate

Question

When unzipping files in Windows, I\'ll occasionally have problems with paths

1. that are too long for Windows (but okay in the original OS that created the file)

Answer 1

For the PathTooLongException problem, I found that you can't use DotNetZip. Instead, what I did was invoke the command-line version of 7-zip; that works wonders.

public static void Extract(string zipPath, string extractPath)
{
    try
    {
        ProcessStartInfo processStartInfo = new ProcessStartInfo
        {
            WindowStyle = ProcessWindowStyle.Hidden,
            FileName = Path.GetFullPath(@"7za.exe"),
            Arguments = "x \"" + zipPath + "\" -o\"" + extractPath + "\""
        };
        Process process = Process.Start(processStartInfo);
        process.WaitForExit();
        if (process.ExitCode != 0) 
        {
            Console.WriteLine("Error extracting {0}.", extractPath);
        }
    }
    catch (Exception e)
    {
        Console.WriteLine("Error extracting {0}: {1}", extractPath, e.Message);
        throw;
    }
}
