Question

So I created a project to test DI in MVC 4. Yeah, that was the easy part. I have a controller that looks like this.

public class CompanyManagementController : Controller
{
     private ICompanyService companyService;

     public CompanyManagementController(ICompanyService companyService)
     {
         this.companyService = companyService;
     }

     public ActionResult Index()
     {
         return View(companyService.GetCurrentCompanies());
     }
}

What I can’t figure out is how to tell the view Index.cshtml that I have this List that I am returning to it. When I have just a POCO it’s easy. I did this

[HttpGet]
public ActionResult Create()
{
    var company = new Company();
    return View(company);
}

[HttpPost]
public ActionResult Create(Company company)
{
    using(var context = new InventoryContext())
    {
        context.Companies.Add(company);
        context.SaveChanges();
    }
    return View("Create");
}

That was super easy because I just said

@model MvcInventoryManager.Models.Company

in the Create.cshtml file.

Any hints? What I want to do is be able to loop through the list of companies that get returned.

Thanks!

Answer 1

What is the return type of companyService.GetCurrentCompanies()? That would be the type you’d want to use for binding the Model in the view. For example, if the type is IEnumerable<Company> then in your view you would declare this:

@model IEnumerable<MvcInventoryManager.Models.Company>

That way the type of the Model property would match what’s being passed to the view and you could loop through the Model:

foreach (var company in Model)
