title: Escape double quotes in a string
body: <p>Double quotes can be escaped like this:</p>
  
  <pre><code>string test = @"He said to me, ""Hello World"". How are you?";
  </code></pre>
  
  <p>But this involves adding character <code>"</code> to the string. Is there a C# function or other method to escape double quotes so that no changing in string is required?</p>
