title: An item with the same key has already been added - csvreader.fieldcount
body: <p>I'm trying to create an import program from CSV.</p>
  
  <p>My code is</p>
  
  <pre><code>csv = New CsvReader(New StreamReader("CSVFileLocation"), True)
  Dim fieldCount As Integer = csv.FieldCount
  </code></pre>
  
  <p>The error message "An item with the same key has already been added." on the second line.
  If I changed "HasReaders" to "False", there's no such error. But, I'm not able to get the Headers. </p>
  
  <p>Could somebody help me on this, please?</p>
  
  <p>FYI: I'm using Visual Studio 2010 version.</p>
