title: Linq check to see is there any NULLs in a set of DataRows?
body: <p>I have a set DataRows and I want to check if any of the fields in any of those rows has a NULL value in it. I came up with this below, but I'm not sure because I'm nesting an ALL.</p>
  
  <pre><code>result.AsEnumerable().AsQueryable().All(o =&gt; o.ItemArray.All(i=&gt;i == DBNull.Value))
  </code></pre>
  
  <p>Hard to tell because I can't put a "watch" in lambdas.</p>
