title: C# query List<Tuple> using LINQ
body: <p>I have a list and I need to start reading when item1 is great than myVariable.
  I can do it using a loop and an if statement but can someone help me to do it using LINQ?</p>
  
  <pre><code>var listDate = new List&lt;Tuple&lt;DateTime, double&gt;&gt;();
  
  foreach (var item in listDate)
  {
      if (item.Item1 &gt; myVariable)
           Console.WriteLine(item);
  }
