  <pre><code>BindingList&lt;ClassName&gt; lst = List.Select(obj =&gt; obj.Number == "NN").ToList&lt;ClassName&gt;();

  <p>List:</p>
  
  <pre><code>BindingList&lt;ClassName&gt; List = new BindingList&lt;ClassName&gt;();

  <p>Erro:</p>
  
  <p>System.Collections.Generic.IEnumerable' does not contain a definition for 'ToList' and the best extension method overload 'System.Linq.Enumerable.ToList(System.Collections.Generic.IEnumerable)' has some invalid arguments</p>
