title: Json.NET object serialization - change indent char
body: <p>I have simple code to serialise my object into JSON:</p>
  
  <pre><code> Dim json As String = JsonConvert.SerializeObject(MyObject, Formatting.Indented)
  </code></pre>
  
  <p>How can I change indent char to "-" in resulting JSON? I know there is <code>JsonTextWriter.IndentChar</code> but I have no clue how to implement it together with <code>JsonConvert.SerializeObject</code></p>
