title: How to get ID node (key) from firebase realtime database on Xamarin.Forms
body: <p>I have a firebase realtime database written like this:</p>
  <pre><code>&quot;Users&quot; : {
      &quot;6SuuMBbymrV0YaiE82YCU8Qz0bj1&quot; : {
        &quot;Name&quot; : &quot;Vincent&quot;,
        &quot;e-Mail&quot; : &quot;vinc.dl@gmail.com&quot;
      }
  </code></pre>
  <p>And I want to get the ID (6SuuMBbymrV0YaiE82YCU8Qz0bj1) and put it in a string variable, so I can use it in a query interrogation (using where).
  .Key and .Uid don't work, so how can I do it?</p>
