        }
        
    }

Answer 1

The System.IO.Compression namespace contains the following types for compressing and decompressing files and streams. You can also use these types to read and modify the contents of a compressed file.

string fileName = Guid.NewGuid() + ifile.FileName;
string path = Path.Combine(FilesTempPath, fileName);
using (var fileStream = new FileStream(path, FileMode.Create))
{
    ifile.CopyTo(fileStream);
}

var FileZipPath = FilesTempPath + "\\" + fileName;
ZipFile.ExtractToDirectory(FileZipPath, FilesTempPath);

Answer 2

The following example from MSDN shows how to use the GZipStream class to compress and decompress a directory of files.
