ASP.Net MVC项目中的HttpCompileException

Question

I'm working on an ASP.Net MVC E-commerce project. I am receiving the following exception.

What is the reason for this exception?

Partial code:

Answer 1

a foreach loop needs a definition of some kind of collection ( List , IEnumerable , etc).

So in order to fix the issue with your partial view.. at the top you need

@model IEnumerable<Ecommerce.Models.Products>

then in your main view add

@Html.Partial("_ProductsView", Model)

so then your foreach is reading.. 'Foreach item in the List of Products' .... perform this operation

Answer 2

With reference of your image its clearing visible that you have forgotten to pass modal to partial view and since the model value is null and if you try iterate so it will throw null object exception. To fix it use following approach.

Replace @Html.Partial("_ProductsView") to @Html.Partial("_ProductsView", Model) in your view and again make sure you are passing model from controller.

One more thing before iterating list do a null check

@if(modal != null)
{
   //do your stuff
}
