Cannot implicitly convert type 'System.Collections.Generic.List to 'Models.CustomerViewModel'


I am trying to pass a list of data containing two objects that are contained in a custom interface,

My interface consists of

public interface ICustomersAndSitesRepository
{
    IQueryable<CustomerSite> CustomerSites { get; }
    IQueryable<Customer> Customers { get; }
    IQueryable<ICustomersAndSitesRepository> CustomerAndSites { get; }
}

Then my repository i have this method

public IQueryable <ICustomersAndSitesRepository> CustomerAndSites
    {
        get { return CustomerAndSites; }
    }

Then i have my viewmodel

public class CustomerSitesListViewModel
{
    public IList<CustomerSite> CustomerSites { get; set; }
    public PagingInfo PagingInfo { get; set; }
    public CustomerViewModel Customers { get; set; }

}

And my controller action

public ViewResult List([DefaultValue(1)] int page)
{

    var customersWithSitesToShow = customersAndSitesRepository.CustomerAndSites;
    var viewModel = new CustomerSitesListViewModel
    {                
        Customers = customersWithSitesToShow.Skip((page - 1) * PageSize).Take(PageSize).ToList(),
        PagingInfo = new PagingInfo
        {
            CurrentPage = page,
            ItemsPerPage = PageSize,
            TotalItems = customersWithSitesToShow.Count()
        }
    };

    return View(viewModel);  //Passed to view as ViewData.Model (or simply model)
}

This line throws an error as im trying to pass the collection to my paging function thats expecting a list.

    Customers = customersWithSitesToShow.Skip((page - 1) * PageSize).Take(PageSize).ToList(),

The error is

 Cannot implicitly convert type 'System.Collections.Generic.List to 'Models.CustomerViewModel'

Is there a way to convert the list that is being returned so that it can be used in the viewmodel?

This is the customer view model

public class CustomerViewModel
{
    public int Id { get; set; }
    public string CustomerName { get; set; }
    public string PrimaryContactName { get; set; }
    public string PrimaryContactNo { get; set; }
    public string PrimaryEmailAddress { get; set; }
    public string SecondaryContactName { get; set; }
    public string SecondaryContactNo { get; set; }
    public string SecondaryEmailAddress { get; set; }
    public DateTime RegisteredDate { get; set; }
    public string WasteCarrierRef { get; set; }
    public string UnitNo { get; set; }
    public string StreetName { get; set; }
    public string Town { get; set; }
    public string County { get; set; }
    public string Postcode { get; set; }
    public byte[] ImageData { get; set; }
    public string ImageMimeType { get; set; }
    public SiteViewModel Site { get; set; }
}

Solution

  • As the error says: the property CustomerSitesListViewModel.Customers is of type CustomerViewModel, but you are trying to assign a List<CustomerSite>.

    Did you mean this instead:

    CustomerSites = customersWithSitesToShow
                      .Skip((page - 1) * PageSize)
                      .Take(PageSize)
                      .ToList()
    

    or maybe this:

    Customers = new CustomerViewModel(customersWithSitesToShow...),
