來自DataTable C＃的不同值

Question

我已經將xml轉換為DataTable 。 我有一個datatable類似這樣的。 它描述了一家特定酒店的房間選擇。 如果板類型，房間類型，房間價格相同，我想將其分為兩個房間。

Room 1

Boards Type            Room Type            Room Price     Sleep Up To

Room Only              Double Standard        301.280       2 Guests    

Room Only              Double Standard        301.280       2 Guests    

我想像這樣。

Room 1

Boards Type            Room Type            Room Price     Sleep Up To

Room Only              Double Standard        301.280       2 Guests  

Room 2

Boards Type            Room Type            Room Price     Sleep Up To

Room Only              Double Standard        301.280       2 Guests  

以下是我嘗試使用的代碼，沒有客人使用。 之后，我發現僅不使用任何客人就無法打破這一點。 所以我想用3列打破它，並想打印為2號房間。

PlaceHolder1.Controls.Add(new LiteralControl("<div class='type1 pd10-lr pd15-tb'>"));

                var noofroom = (from row2 in dt2.AsEnumerable()
                                where (Int64)row2["hotelcode"] == hotelcode
                                     select row2.Field<string>("guests")).Distinct();

                int a = 1;

                foreach (var rcount in noofroom)
                {


                        PlaceHolder1.Controls.Add(new LiteralControl("<div class='rhead'>" +
                 "Room " + a + "" +
                 "</div>" +
                            "<table class='roomtbl'>" +
                         "<tr>" +
                             "<td class='tdaltbg'>" +
                                 "<strong>&nbsp;" +
                             "Board Type</strong></td>" +
                             "<td class='style30'>" +
                                 "<strong>&nbsp;" +
                             "Room Type</strong></td>" +
                             "<td class='tdaltbg'>" +
                                 "<strong>&nbsp;&nbsp; Room Price</strong></td>" +
                                 "<td class='style30'>" +
                                 "<strong>&nbsp;" +
                             "Sleep Up To</strong></td>" +
                             "<td class='tdaltbg'>" +
                                 "<strong></strong></td>" +
                         "</tr>"));

                        DataRow[] drs = dt2.Select("hotelcode='" + hotelcode + "' AND guests='" + rcount + "'");
                        foreach (DataRow dr in drs)
                        {
                            PlaceHolder1.Controls.Add(new LiteralControl("<tr>" +
                                  "<td class='tdaltbg'>" +
                                     "&nbsp;" +
                                     "" + dr["board"] + "</td>" +
                                "<td class='style30'>" +
                                     "" + dr["roomtype"] + "</td>" +
                                 "<td class='tdaltbg'>" +
                                     "&nbsp;" +
                                     "£ " + dr["amount"] + "</span></td>" +
                                       "<td class='style30'>" +
                                     "&nbsp;" +
                                     " " + dr["guests"] + " Guests</span></td>" +
                                 "<td class='tdaltbg'>"));

                            PlaceHolder1.Controls.Add(new LiteralControl("<input type='radio' name='t1' data-price='308.560' checked='checked'/>" +
                                 "</td>" +

                             "</tr>"));
                        }
                        PlaceHolder1.Controls.Add(new LiteralControl("</table>"));
                        a++;

                }

請嘗試這個。 在這里，可以將多個列作為參數傳遞，對於true則傳遞true。
