title: How do I use lambda expressions to filter DataRows?
body: <p>How can I search rows in a datatable for a row with Col1="MyValue"</p>
  
  <p>I'm thinking something like</p>
  
  <pre><code>Assert.IsTrue(dataSet.Tables[0].Rows.
      FindAll(x =&gt; x.Col1 == "MyValue" ).Count == 1);
  </code></pre>
  
  <p>But of course that doesn't work!</p>
