Create a ZipArchive from the ZipFile, and use the ExtractToFile method if the file type is acceptable:

C#

using (ZipArchive zip = ZipFile.Open(zipfile, ZipArchiveMode.Read))
    foreach (ZipArchiveEntry entry in zip.Entries)
        {
        string ext = Path.GetExtension(entry.Name).ToLower();
        if(ext == ".txt" || ext == ".xlsx")
            {
            ... sort out where you want to put it ...
            entry.ExtractToFile(outputFileNameAndPath);
            }
        }

ZipFile.Open(zipfile, ZipArchiveMode.Read)).here "zipfile" means what

What *might* be useful when opening a file?

ANd what error might that be?
What is the exact path you have given as shown with the debugger? How doesthat compare to the file system?

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - we get no other context for your project.
Imagine this: you go for a drive in the country, but you have a problem with the car. You call the garage, say "it broke" and turn off your phone. How long will you be waiting before the garage arrives with the right bits and tools to fix the car given they don't know what make or model it is, who you are, what happened when it all went wrong, or even where you are?
