title: Indexed retrieval SortedDictionary<>
body: <p>I read <a href="http://msdn.microsoft.com/en-us/library/5z658b67.aspx" rel="noreferrer">here</a> that SortedDictionary does not allow indexed retrieval unlike SortedList.
  Then how can I get the <code>nameAddr["C"]</code> correctly in the following code snippet?</p>
  
  <pre><code>        SortedDictionary&lt;string, string&gt; nameAddr = new SortedDictionary&lt;string, string&gt;();
          nameAddr.Add("X", "29");
          nameAddr.Add("A", "30");
          nameAddr.Add("C", "44");           
  
          Console.WriteLine(nameAddr["C"]);
  </code></pre>
