title: What does the @ prefix do on string literals in C#
body: <p>I read some C# article to combine a path using <code>Path.Combine</code>(part1,part2).</p>
  
  <p>It uses the following:</p>
  
  <pre><code>string part1 = @"c:\temp";
  string part2 = @"assembly.txt";
  </code></pre>
  
  <p>May I know what is the use of <code>@</code> in part1 and part2?</p>
