Question

Im using the ZipDotNet library for C#.

I created a byte array with random data like this:

public static byte[] GetRandomBytes(int Length)
        {
            byte[] data = new byte[Length];
            Random random = new Random();
            random.NextBytes(data);
            return data;
        }

Now I want to zip those bytes to a MemoryStream and return the MemoryStream as byte array too.

public static byte[] zipFileToStream(byte[] file)
        {
            using (MemoryStream memStream = new MemoryStream())
            {
                using (ZipFile zip = new ZipFile())
                {
                    zip.AddEntry("file.txt", file);
                    zip.Save(memStream);
                }
                return memStream.ToArray();
            }
       }

When I print out the returning byte array, then there are always the same bytes in?

Can anyone help me with my issue?

Setting the MemoryStrream Position to 0 solved the issue.
