title: C# build JSON string that has semicolons in the data
body: <p>I am creating a string as follows:</p>
  
  <pre><code>string title = "Q:hello";
  </code></pre>
  
  <p>I then want to embed this string in a JSON string to send to the client.  How do I escape the semicolon?  I don't want to use a library.</p>
