在 ASP.NET Core MVC 中顯示每個人的總值

Question

我有一個籃球統計數據的數據庫表，我想知道顯示一個單獨的表的簡單方法，該表顯示每個球員的每個統計數據的總數。

我在下面有一張圖片，展示了統計表的樣子。

我是 .NET 的新手，所以我不太確定最好的方法是什么。 我在互聯網上環顧四周，但找不到與我的問題類似的東西。

Answer 1

您可以添加顯示每個統計數據總和的表格，例如

<-----table----->
-----------------
| Player | Total |
------------------
| Player1 | 54   |
| Player2 | 60   |
| Player3 | 75   |
| Player4 | 80   |
| Player5 | 90   |
------------------

在 Html 中添加表並使用相同的模型創建此表。 在列中的每個循環 sum stat 中，例如：

    <table>
      <thead>
        <th>Player Name</th>
        <th>Stat Total</th>
     </thead>
     <tbody>
        @foreach (var stat in Model)
         {
          <tr>
            <td width ="10%">@stat.Player.FirstName @stat.Player.LastName</td>
            <td width ="10%">@stat.Points + @stat.Rebounds + @stat.Assists + @stat.Steals + @stat.Blocks</td>
          </tr>
         }
    </tbody>
  </table>

由於 stat 模型屬性數據類型是“int”，您可以輕松地將它們相加以獲得總數。
