Question

I have a collection:

            var results =
            from result in xml.Descendants(ns + "GetQuoteResult")
            select new SpotPriceModel
            {
                Type = result.Element(ns + "Type").Value,
                Currency = result.Element(ns + "Currency").Value,
                Date = result.Element(ns + "Date").Value,
                Time = result.Element(ns + "Time").Value,
                Rate = (decimal)result.Element(ns + "Rate"),
                Bid = (decimal)result.Element(ns + "Bid"),
                BidTime = result.Element(ns + "BidTime").Value,
                ExpTime = result.Element(ns + "ExpTime").Value,
                DisplayTime = result.Element(ns + "DisplayTime").Value,
                DisplayDate = result.Element(ns + "DisplayDate").Value,
                Ask = (decimal)result.Element(ns + "Ask"),
                AskTime = result.Element(ns + "AskTime").Value
            };

        var spot = results.First();

        return View(spot);
    }

And I have created a model of that collection:

    public class SpotPriceModel
{
    public string Type { get; set; }
    public string Currency { get; set; }
    public DateTime Date { get; set; }
    public DateTime Time { get; set; }
    public decimal Rate { get; set; }
    public decimal Bid { get; set; }
    public DateTime BidTime { get; set; }
    public DateTime ExpTime { get; set; }
    public DateTime DisplayTime { get; set; }
    public DateTime DisplayDate { get; set; }
    public decimal Ask { get; set; }
    public DateTime AskTime { get; set; }
}

I am trying to scaffold a view model of ‘spot’.

But when I compile, I get the following error:

The model item passed into the dictionary is of type 'BD.Models.SpotPriceModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[BD.Models.SpotPriceModel]'.

The view is expecting the following model type:

@model IEnumerable<BD.Models.SpotPriceModel>

Answer 1

You haven’t specified the type in your Linq query and so have created an anonymous type instead of SpotPriceModel.

         select new SpotPriceModel
        {
            Type = result.Element(ns + "Type").Value,
            Currency = result.Element(ns + "Currency").Value,
            Date = result.Element(ns + "Date").Value,
            Time = result.Element(ns + "Time").Value,
            Rate = (decimal)result.Element(ns + "Rate"),
            Bid = (decimal)result.Element(ns + "Bid"),
            BidTime = result.Element(ns + "BidTime").Value,
            ExpTime = result.Element(ns + "ExpTime").Value,
            DisplayTime = result.Element(ns + "DisplayTime").Value,
            DisplayDate = result.Element(ns + "DisplayDate").Value,
            Ask = (decimal)result.Element(ns + "Ask"),
            AskTime = result.Element(ns + "AskTime").Value
        };
