EF查询返回DataTable

using (SchoolContext dbCOntext = new SchoolContext())
            {
                string str = "select * from student";
                System.Data.Common.DbCommand cmd = dbCOntext.Database.Connection.CreateCommand();
                cmd.CommandText = str;
                cmd.CommandType = CommandType.Text;
                //转成sqlcommand正常查询语句。
                MySql.Data.MySqlClient.MySqlDataAdapter da = new MySql.Data.MySqlClient.MySqlDataAdapter();
                da.SelectCommand = cmd as MySql.Data.MySqlClient.MySqlCommand;
                DataTable dt = new DataTable();
                da.Fill(dt);                //List<Student> lst = (from d in dbCOntext.Students where d.StudentName == "New Student" select d).ToList();
                //List<Student> lst1 = (from d in dbCOntext.Students select d).ToList();
            }

根据上文EF动态新建数据库/表
