title: Read double value from a file C#
body: <p>I have a txt file that the format is:</p>
  
  <pre><code>0.32423 1.3453 3.23423
  0.12332 3.1231 9.23432432
  9.234324234 -1.23432 12.23432
  ...
  </code></pre>
  
  <p>Each line has three double value. There are more than 10000 lines in this file. I can use the ReadStream.ReadLine and use the String.Split, then convert it.
  I want to know is there any faster method to do it.</p>
  
  <p>Best Regards,</p>
