突出最低价格

Question

目标

获取并突出显示a中小数点之间的最低价格foreach.

场景

我正在比较一些市场之间的各种产品价格.结果显示在HTML中table.该表的最后一行包含总价值,即每个产品每个市场价格的总和.

例如:

                 Market 1    Market 2  
 Xbox 360        US$119,00   US$125,00 
 Playstation 3   US$129,00   US$119,00 
 Total           US$248,00   US$244,00

View背后的代码是:

@foreach (var item in Model.Collection.Products.DistinctBy(p => p.id))
{
    <tr>
        <td>
            <p>@item.name</p>
        </td>

        @foreach (var market in Model.Markets)
        {
            <td>
                @foreach (var product in Model.Collection.Products.Where
                    (p => p.productId == item.productId && 
                     p.marketId == market.id))
                {
                    <p>@product.price</p>
                }
            </td>
        }
    </tr>
}

<tr>
    @foreach (var market in @Model.Markets)
    {
        <td class="total">
            @{
                decimal totalValue = 
                    Model.Collection.GetTotalPrice(market.marketId);
            }

            @if (totalValue == 0)
            {
                <h2>Unavailable</h2>
            }
            else
            {
                <h2>US$@totalValue</h2>
            }
        </td>
    }
</tr>

到现在为止还挺好.现在出现问题:我想强调市场之间的最低价格(最低总价) - 我该怎么做？

Answer 1

您可以将最低价格拉出来并将其用作基准.如果该特定市场的产品价格最低,则此示例在价格标签lowest上设置类别<p><=

@foreach (var market in Model.Markets)
{
    @{ 
        var marketProducts = Model.Collection.Products.Where(p => p.productId == item.productId && p.marketId == market.id).ToList();
        var lowestMarketPrice = marketProducts.Min(p => p.price);
    }
    <td>
        @foreach (var product in marketProducts)
        {
            <p @(product.price <= lowestMarketPrice ? "class=lowest" : "")>@product.price</p>
        }
    </td>
}

根据您的澄清,这里是你如何能凸显最低总跨任何市场

@{ 
    var marketTotals = Model.Markets.ToDictionary(m => m.marketId, m => Model.Collection.GetTotalPrice(m.marketId));
    var lowestTotal = marketTotals.Min(t => t.Value);
}
@foreach (var price in marketTotals)
{
    <td @(price.Value <= lowestTotal ? "class=total-lowest" : "class=total")>
        <h2>@{ price.Value == 0 ? "Unavailable" : String.Format("US${0}", price.Value) }</h2>
    </td>
}
