Maximum (M) amount of products shown on the Product page (show only first M products, others – ignored; if M == 0, then show all products)

How can I do this condition? Do I need to do it in ProductPageModel or Product.cshtml?

product.cshtml

@page
@model GetandTake.Pages.ProductModel
@{
}
<table >

    <thead>
        <tr>
            <th scope="col">ProductName</th>
            <th scope="col">QuantityPerUnit</th>
            <th scope="col">UnitPrice</th>
            <th scope="col">UnitsInStock</th>
            <th scope="col">UnitsOnOrder</th>
            <th scope="col">ReorderLevel</th>
            <th scope="col">Discontinued</th>
            <th scope="col">Category</th>
            <th scope="col">Supplier</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var product in Model.Products)
        {
            <tr>
                <td>@product.ProductName</td>
                <td>@product.QuantityPerUnit</td>
                <td>@product.UnitPrice</td>
                <td>@product.UnitsInStock</td>
                <td>@product.UnitsOnOrder</td>
                <td>@product.ReorderLevel</td>
                <td>@product.Discontinued</td>
                <td>@product.Category</td>
                <td>@product.Supplier</td>
            </tr>

        }
    </tbody>
</table>

ProductModel product.cshtml.cs

public class ProductModel : PageModel
{
    private readonly IProductService _productService;

    public IEnumerable<ProductsDTO> Products { get; private set; }

    public ProductModel(IProductService productService)
    {
        _productService = productService;
    }

    public void OnGet()
    {
        Products = _productService.GetAll();
    }
}

CodePudding user response：

if you just need to show the M first Products, just add the .Take() method from System.Linq

public void OnGet()
{
    Products = _productService.GetAll().take(M);
}

Where M is your max products number.

This is only acceptable if you're NOT seeking for pagination, but just displaying N first products.
As this is a business rule, try to put it in C# file, not in .cshtml
