Answer 1

 var termAttr = tokenStream.GetAttribute<Lucene.Net.Analysis.Tokenattributes.ITermAttribute>(); while(tokenStream.IncrementToken()) { string term = termAttr.Term; } 

Answer 2

In Apache Lucene.Net 4.8, you can use this C # code: (.NET Core 2+), where term = termAttr.ToString() contains the token as a string . Full method: PrintTokens(Analyzer analyzer, string fieldName, string text) you can get in GitHub msigut / LuceneNet48Demo .

  var tokenStream = analyzer.GetTokenStream(fieldName, textToAnalyze); var termAttr = tokenStream.GetAttribute<ICharTermAttribute>(); tokenStream.Reset(); while (tokenStream.IncrementToken()) { string term = termAttr.ToString(); }
