title: sum up json values
body: <p>I'm trying to sum up all the values in the json that contain the string "Example". But I have no idea how to do it.
  I'm using the "Newtonsoft.Json" framework.</p>
  
  <pre><code> {
        "Example1344": 13,
        "Example925": 16,
        "Example454Example": 24,
        "Nothing": 51,
        "Other9235": 45
        }
  </code></pre>
  
  <p>So that the result would be 53</p>
