title: Stream TextReader to a File
body: <p>I have a <code>TextReader</code> object.</p>
  
  <p>Now, I want to stream the whole content of the <code>TextReader</code> to a File. I cannot use <code>ReadToEnd()</code> and write all to a file at once, because the content can be of high size.</p>
  
  <p>Can someone give me a sample/tip how to do this in Blocks?</p>
