title: How to write/modify/add some text in a file stored in azure file storage?
body: <p>My goal is to modify a <code>.txt</code> file in azure file storage using WindowsAzure.Storage API. I would like to know if there is any method to add some text in the file.</p>
  
  <p>Is it easier to use the <code>System.IO</code> API?</p>
  
  <p>I've already tried the <code>cloudFileStream.Write()</code> but it didn't work.</p>
  
  <p>Thank you</p>
