c# - Difference between using StreamReader.ReadLine and StreamReaderEnumerable -


is there difference between these 2 codes?

1.        using (streamreader sr = new streamreader("filepath"))   {              while ((string line = sr.readline()) != null)       {           dosomething();       }   }   2.      foreach (string line in new streamreaderenumerable("filepath"))    {        if (line != null)        {            dosomething();        }    }

is there performance concern when using 1 on other, or functional identical during runtime?

according definition steamreaderenumerable, streamreader.readline() used. noticed custom solution solution uses same method. result, recommend using option 1 since not using linq work lines. way can avoid overhead of steamreaderenumerable class.

if did need use linq access lines, steamreaderenumerable class provide simple , robust way of doing so.
