title: Get specific json elements
body: <p>I couln't find a similar case here, hence my question. I have a json like this:</p>
  
  <pre><code>{
    "prop1": "bla",
    "propn": "bla",
    "Data": {
      "42": {
        "prop1": "bla",
        "prop2": "bla",
        "Symbol": "42"
      },
      "abc": {
        "prop1": "bla",
        "prop2": "bla",
        "Symbol": "abc"
      }
    },
    "Type": 100
  }
  </code></pre>
  
  <p>Now, how do I get all elements from Data, and the most I am interested in the ones that have the symbol property set. I tried Newtonsoft.json.linq and jobject, but got really no clue what to do here. Any guidance anyone? Thanks!
