title: Querying DataColumnCollection with LINQ
body: <p>I'm trying to perform a simple LINQ query on the Columns property of a DataTable:</p>
  
  <pre><code>from c in myDataTable.Columns.AsQueryable()
      select c.ColumnName
  </code></pre>
  
  <p>However, what I get is this:</p>
  
  <blockquote>
    <p>Could not find an implementation of the query pattern for source type 'System.Linq.IQueryable'. 'Select' not found.  Consider explicitly specifying the type of the range variable 'c'.</p>
  </blockquote>
  
  <p>How can I get the DataColumnCollection to play nice with LINQ?</p>
