Question

Im uploading zip file (compressed with winrar) to my server by FileUpload control. On the server I use this code to decompress file:

HttpPostedFile myFile = FileUploader.PostedFile;

            using (Stream inFile = myFile.InputStream)
            {
                using (GZipStream decompress = new GZipStream(inFile, CompressionMode.Decompress))
                {
                    StreamReader reader = new StreamReader(decompress);
                    string text = reader.ReadToEnd(); // Here is an error
                }
            }

But I get error:

The magic number in GZip header is not correct. Make sure you are passing in a GZip stream

Is there any way to repair this ? Im using .net 2.0

Thank You very much for help

ZIP and GZIP are not quite the same. You can use a third-party library like #ziplib to decompress ZIP files.
