强类型 DataSet 删除数据库中的记录

FeifeiDataSet fds = new FeifeiDataSet(); FeifeiDataSetTableAdapters.studentTableAdapter stuTblapt = new FeifeiDataSetTableAdapters.studentTableAdapter(); stuTblapt.Fill(fds.student); FeifeiDataSet.studentRow reStuRow = fds.student.FindBystu_id(10010); fds.student.RemovestudentRow(reStuRow); stuTblapt.Update(reStuRow); foreach (FeifeiDataSet.studentRow sr in fds.student.Rows) { Console.WriteLine(sr.stu_id + " " + sr.stu_name + " " + sr.stu_address); }
运行之后,内存中记录删除,但数据库却没删除.....为什么?
