Lucene.Net怎样对doc文件建立索引啊

Question

我现在做的只能对纯文字文件进行索引，如何对doc或docx进行内容索引？
下面这段换成doc就不行了 IndexWriter writer = null; 
                        Document doc = new Document(); 
writer = new IndexWriter(@"E:\ss\i", new StandardAnalyzer(), true);  StreamReader sr = new StreamReader(@"E:\ss\111.txt", System.Text.Encoding.GetEncoding("gb2312"));
doc.Add(new Field(@"E:\ss\111.txt", "name", Field.Store.YES, Field.Index.UN_TOKENIZED));
doc.Add(new Field("content", sr.ReadToEnd().ToString(), Field.Store.YES, Field.Index.TOKENIZED));
sr.Close();
doc.Add(Field.UnIndexed("filename", "111.txt")); 
writer.AddDocument(doc);
writer.Optimize();
writer.Close();

public void CreateMarketIndex(DataSet dsMarketResult)
        {
            try
            {
                IndexWriter writer = new IndexWriter(indexpath, getAnalyzer(), true);
                writer.mergeFactor = 3000;
                writer.minMergeDocs = 3000;
                writer.maxMergeDocs = int.MaxValue;
                for (int i = 0; i < dsMarketResult.Tables[0].Rows.Count; i++)
                {
                    Document doc = new Document();
                    doc.Add(Field.Keyword("id", dsMarketResult.Tables[0].Rows[i][0].ToString()));
                    doc.Add(Field.UnIndexed("title", ClassIndex.RemoveHTML(dsMarketResult.Tables[0].Rows[i][1].ToString())));
                    string content = dsMarketResult.Tables[0].Rows[i][1].ToString();
                    //content += dsMarketResult.Tables[0].Rows[i][2].ToString();
                    doc.Add(Field.Text("content", ClassIndex.RemoveHTML(content)));
                    writer.AddDocument(doc);
                }
                writer.Optimize();
                writer.Close();
            }
            catch(Exception exp2)
            {
                System.IO.StreamWriter write = new System.IO.StreamWriter(@"d:\index\createindexlog.txt", true, System.Text.Encoding.Unicode, 10240);
                write.WriteLine("记录时间：" + DateTime.Now.ToString());
                write.Write(exp2.ToString());
                write.Flush();
                write.Close();
            }
        }

4楼的dsMarketResult哪来的，如何和doc、xls文件结合呀

Answer 4

doc、xls先要读出里面的文本,不能直接对文件建索引的.
