Listing 5-19. The Contents of the DemoArray.cshtml File
@model Razor.Models.Product[]
@{
}
ViewBag.Title = "DemoArray";
Layout = "∼/Views/_BasicLayout.cshtml";
@if (Model.Length > 0) {
ProductPrice
@foreach (Razor.Models.Product p in Model) {
@p.Name
$@p.Price
}
} else {
No product data
}
I used an @if statement to vary the content based on the length of the array that I receive as the view model and a
@foreach expression to enumerate the contents of the array and generate a row in an HTML table for each of them. You can
see how these expressions match their C# counterpart. You can also see how I created a local variable called p in the foreach
loop and then referred to its properties using the Razor expressions @p.Name and @p.Price.
The result is that I generate an h2 element if the array is empty and produce one row per array item in an HTML table
otherwise. Because my data is static in this example, you will always see the same result, which I have shown in Figure 5-13.
