我只想在 div 标签中显示两个项目。所以第一个 div 标签会显示两个项目或产品，然后我会添加另一个 div 标签来显示接下来的两个。我无法更改 db.Query，因为我需要来自该特定部门的数据。有没有办法做到这一点？我应该使用除 foreach 循环以外的东西吗？任何帮助，将不胜感激。如果我想要的东西令人困惑，请告诉我。谢谢！

@{
    var db = Database.Open("Kudler Internet");
    var products = db.Query("SELECT * FROM Inventory  WHERE Department='Bakery'");

}

for您可以为此使用循环的递增值。像这样的东西：

<div class="grid_6 content border_left">
@for (var i = 0; i < products.Count(); i++)
{
    <h1>@products[i].InventoryItem</h1>
    <p>@products[i].Price</p>
    <p>@products[i].Units</p>
    <br/>
    @if (i % 2 == 1)
    {
        </div>
        <div class="grid_6 content border_left">
    }
}
</div>

这应该正常输出h1andp元素，并且循环的每第二次迭代也输出div元素的关闭和重新打开。

我会使用 Linq 分组将项目组合成 2 个组。像这样：

@foreach (var grp in products
    .Select((index, item) => { index = index, item = item }))
    .GroupBy(item => item.index / 2))
{
    <div class="grid_6 content border_left">
        @foreach (var p in grp)
        {
            <h1> @p.item.InventoryItem</h1>
            <p> @p.item.Price</p>
            <p> @p.item.Units </p>
            <br/>
        }
    </div>
}
