C# 数据表c中的不同值

我已经将xml转换为DataTable。我有一个类似这样的数据表。请描述一家特定酒店的客房选择。我想把它分成两个房间，如果木板类型，房间类型，房间价格都一样的话

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    

我想让它像这样

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  

下面是我的代码，我已尝试使用“无来宾”来破解此代码。在那之后，我发现仅仅用不带客人的方式来打破这一局面是不正确的。所以我想用3列来打破这一点，并想打印成房间2

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++;

                }

请试试这个。这里可以将多个列作为参数传递，对于distinct为true。
