title: Is there a C# IN operator?
body: <p>In SQL, you can use the following syntax:</p>
  
  <pre><code>SELECT *
  FROM MY_TABLE
  WHERE VALUE_1 IN (1, 2, 3)
  </code></pre>
  
  <p>Is there an equivalent in C#?  The IDE seems to recognise "in" as a keyword, but I don't seem to be able to find any information on it.</p>
  
  <p>So, is it possible to do something like the following:</p>
  
  <pre><code>int myValue = 1;
  if (myValue in (1, 2, 3))
      // Do something
  </code></pre>
  
  <p>Instead of</p>
  
  <pre><code>int myValue = 1;
  if (myValue == 1 || myValue == 2 || myValue == 3)
      // Do something
  </code></pre>
