title: ArrayList C# Contains method query
body: <p>I have an <code>ObservableCollection&lt;myClass&gt;</code> list. It contains a 10 objects of type <code>MyClass</code>.</p>
  
  <pre><code>class MyClass
  {
    string name;
    int age;
  }
  </code></pre>
  
  <p>If I want to find all items in list where <code>age = 10</code>, can I use the <code>Contains</code> method?
  If yes how can I do this without using iteration?</p>
