除了用FileStream外，用OleDbConnection连接 TXT，达到读取的目的

string path = "D:\\"; string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Text;HDR=Yes;FMT=Delimited\""; OleDbConnection con = new OleDbConnection(conStr);//连接读取txt驱动 OleDbDataAdapter oda = null;//适配器 DataTable tblDatas = new DataTable();//存储的dt string sql = "select 时间 ,Value1 from 20110826.txt "; oda = new OleDbDataAdapter(sql, con); oda.Fill(tblDatas); 如上利用OleDbConnection 达到读取TXT为数据源的目的
