   Hi,
   
   I am going through the Lucene 4 Cookbook's example. Not sure how to revise 
the Java version's codes to C# as shown below. 
   
   original code : Line 55, 56
   revised code: Line 57, 58

   Any suggestion? Thanks.
   
   ```csharp
   StringReader reader = new StringReader("Lucene is mainly used for 
information retrieval and you can read more about it at lucene.apache.org.");
   StandardAnalyzer wa = new StandardAnalyzer(luceneVersion);
   TokenStream ts = null;
   
   try
   {
       ts = wa.GetTokenStream("field", reader);
       OffsetAttribute offsetAtt = ts.addAttribute(OffsetAttribute.class);
       CharTermAttribute termAtt = ts.addAttribute(CharTermAttribute.class);
       //var offsetAtt = ts.AddAttributeImpl(typeof(OffsetAttribute)) as 
OffsetAttribute;
       //CharTermAttribute termAtt = ts.AddAttribute<CharTermAttribute>();
       ts.Reset();
   
       while (ts.IncrementToken())
       {
           String token = termAtt.ToString();
           Console.WriteLine("[" + token + "]");
           Console.WriteLine("Token starting offset: " + offsetAtt.StartOffset);
           Console.WriteLine(" Token ending offset: " + offsetAtt.EndOffset);
           Console.WriteLine();
       }
       ts.End();
   }
   ```
