.net core Convert byte[] to list<string>

Question

in my project I use ISession to store a string list in session cache like this:

var cacheData= someStringList;
var byteArrayCache = CacheHelper.convertListToByteArray(cacheData);
HttpContext.Session.Set(CacheKeys.CacheKey, byteArrayCache);

the ISession Set method needs a byte[] as parameter.

Then I execute the GET method like this:

var byteArrayResponse = HttpContext.Session.Get(CacheKeys.CacheKey);

This GET is returned as a byte[] and I need to convert back to string list but I'm not being able to achieve it.

Any Ideas?

the ConvertListToByteArray method is the following:

 public static byte[] convertListToByteArray(List<string> list)
        {
            byte[] dataAsBytes = list.SelectMany(s =>
            System.Text.Encoding.UTF8.GetBytes(s + Environment.NewLine)).ToArray();

            return dataAsBytes;
        }

To convert the byte[] into List: You will need to remove the newline from the byte[] then loop through each char then add to the new list.

List<string> list = new List<string>();
foreach(byte byt in dataAsBytes) {
if(!byt.Equals(Environment.NewLine)) {
list.Add(byt.ToString());
}
}
return list.ToList();
