获取列表项中的最低/最高价格

Question

The goal

Highlight (on HTML) the item whose its price it is the lowest or biggest of a list of items.

The scenario

There is a List<Products> on my application. Four items of this list are illustrated by:

Item 01

• Product Name: Xbox 360
• Market Name: Bestbuy
• Price: US$159,90

Item 02

• Product Name: Xbox 360
• Market Name: Walmart
• Price: US$129,90

Item 03

• Product Name: Xbox 360
• Market Name: eBay
• Price: US$125,00

Item 04

• Product Name: Xbox 360
• Market Name: Amazon
• Price: US$119,90

As you can see, there is a biggest price as well as a lowest price — and I want to highlight them on HTML with some classes.

Code spotlight

The markup is:

<div class="body">
    <table class="table table-bordered table-hover">
        @foreach (var item in Model.ProductList)
        {
            <tr>
                <td><img src="@item.marketName" /></td>
                <td>US$@item.productPrice</td>
            </tr>
        }
    </table>
</div>

The foreach above iterates with the list ( Model.ProductList ) that I've mentioned before.

The question

With all those information, how can I get the lowest/biggest price of some item of this foreach ?

What I've already tried

I have already tried this:

@Model.ProductList.Min()

But this fragment of code doesn't make sense — is it to get the min of what? . Maybe something like this (of course doesn't work, but just to illustrate):

@Model.ProductList.productPrice.Min()

Ambiguous question?

I searched on Google and StackOverflow about this subject, but without success — no results found.

您需要将Lambda表达式传递给Min()来计算最小化的值：

Model.ProductList.Min(p => p.ProductPrice)
