Obvious Extension Method: TextReader GetLines()

I don’t know about you, but looping through a TextReader or StreamReader looks ugly to me. I’d rather have the lines of the file returned as an IEnumerable<string>

So here it is. Easy Schpeasy.


  1.     public static class TextReaderExtensions
  2.     {
  3.         public static IEnumerable<string> GetLines(this TextReader streamReader)
  4.         {
  5.             string fileLine;
  6.             while ((fileLine = streamReader.ReadLine()) != null)
  7.             {
  8.                 yield return fileLine;
  9.             }
  10.         }
  11.     }

Now the code using it looks like this:

  1.             using (var reader = new StreamReader("someFile.txt"))
  2.             {
  3.                 foreach (var fileLine in reader.GetLines())
  4.                 {
  5.                     //pretty!
  6.                 }
  7.             }

…and you can use all your favorite Linq on there!
