title: Adding double quotes to @ string
body: <p>As far as i understood, a string with an @ in required a set of double quotes to insert the quote in to the string?</p>
  
  <p>I have tried that principle and to no avail. The following line works, but if i were to replace those strings with parameter values then i cant seem to get the correct compilation value</p>
  
  <pre><code>var node = doc.SelectSingleNode(@"//node[@label = ""Chemist Name""]/node[@label = ""John,Smith""]");
  </code></pre>
  
  <p>my attempt (of which i have tried several versions and ended up here, where i have now givn up !)</p>
  
  <pre><code>var node = doc.SelectSingleNode(@"//node[@label = " + ""+parentID+"" + "]/node[@label = " + ""+ name +"" + "]");
  </code></pre>
  
  <p>can anyone help me please? </p>
