how to convert IEnumerable to byte[] in c# is there any option in c#. the IEnumerable may contain large data

IEnumerable string > myStrings = new [] { "hello" , "world" }; var myBytes = myStrings.SelectMany(s => Encoding.UTF8.GetBytes(s)).ToArray(); This will use UTF8 as encoding for the bytes. You might need to use a different encoding depending on what you want to do with the bytes afterwards. Note that - as written above - this is not directly reversible because you lose the information where one string ends and where the next one starts. If you want to, you could a NewLine (or any other identifier that you could use afterwards to split on) after each string to keep them separate: var myBytes = myStrings.Select(s => s + Environment.NewLine) . SelectMany(s => Encoding.UTF8.GetBytes(s)).ToArray();
