"File not found exception" trying to extract zip archive with DotNetZip

Question

public void ZipExtract(string zipfilename, string outputDirectory)
{       
    using (ZipFile zip = ZipFile.Read(zipfilename))//file not found exception
    {
        Directory.CreateDirectory(outputDirectory);
        zip.ExtractSelectedEntries("name=*.jpg,*.jpeg,*.png,*.gif,*.bmp", " ", 
            outputDirectory, ExtractExistingFileAction.OverwriteSilently);
    }
}

[HttpPost]
public ContentResult Uploadify(HttpPostedFileBase filedata)
{
    var path = Server.MapPath(@"~/Files");
    var filePath = Path.Combine(path, filedata.FileName);
    if (filedata.FileName.EndsWith(".zip"))
    {
        ZipExtract(filedata.FileName,path);
    }
    filedata.SaveAs(filePath);
    // CreateThumbnail(filePath);
    _db.Photos.Add(new Photo
        {
            Filename = filedata.FileName
        });

    _db.SaveChanges();
    return new ContentResult{Content = "1"};  
}

I try to extract the uploaded zip archive and save extracted files in a folder but "file not found" exception happens all the time. What's the mistake?

Answer 1

Have you tried setting a break point here, and see what value filedata.FileName has? (And see if it actually exists on the server.)

if (filedata.FileName.EndsWith(".zip"))
      {
        ZipExtract(filedata.FileName,path);
     }
