C# 调试-将数据从控制器传递到视图

我有一个收藏：

            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);
    }

    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; }
}

我为该系列创建了一个模型：

            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);
    }

    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; }
}

我正在尝试构建一个“spot”视图模型

但是当我编译时，我得到以下错误：

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]'.

视图应为以下模型类型：

@model IEnumerable<BD.Models.SpotPriceModel>

@model IEnumerable

您没有在Linq查询中指定类型，因此创建了一个匿名类型而不是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
        };

您尚未在Linq查询中指定类型，因此创建了一个匿名类型而不是SpotPriceModel

         select new SpotPriceModel
        {
            Type = result.Element(ns + "Type").Value,
            Currency = result.Element(ns + "Currency").Value,
            Date = result.Element(ns + "Date").Value,

尝试使用匿名类型，而不是使用匿名类型

IEnumerable<SpotPriceModel> 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
            }).AsEnumerable();    
        //var spot = results.First();    
        return View(results);
    }

IEnumerable results=（来自xml.subjects（ns+“GetQuoteResult”）中的结果）
选择新模型
{
类型=结果.元素（ns+“类型”）.值，
货币=结果元素（ns+“货币”）。值，
日期=结果元素（ns+“日期”）。值，
时间=结果元素（ns+时间“）。值，
速率=（十进制）结果元素（ns+“速率”），
Bid=（十进制）结果元素（ns+“Bid”），
BidTime=结果元素（ns+“BidTime”）.值，
ExpTime=result.Element（ns+“ExpTime”）.Value，
DisplayTime=result.Element（ns+“DisplayTime”）.Value，
DisplayDate=结果.元素（ns+“DisplayDate”）.值，
Ask=（十进制）result.Element（ns+“Ask”），
AskTime=result.Element（ns+“AskTime”）.Value
}).AsEnumerable（）；
//var spot=results.First（）；
返回视图（结果）；
}

不要使用匿名类型，请尝试

IEnumerable<SpotPriceModel> 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
            }).AsEnumerable();    
        //var spot = results.First();    
        return View(results);
    }

IEnumerable results=（来自xml.subjects（ns+“GetQuoteResult”）中的结果）
选择新模型
{
类型=结果.元素（ns+“类型”）.值，
货币=结果元素（ns+“货币”）。值，
日期=结果元素（ns+“日期”）。值，

速率=（十进制）结果元素（ns+“速率”），
Bid=（十进制）结果元素（ns+“Bid”），

模型在视图中声明为什么类型？模型在视图中声明为什么类型？感谢您的回复。我现在有一个新问题。。。我已经更新了这个问题。太好了，它起作用了。我的第二个问题是，我构建了一个列表，而不是详细信息视图。感谢您的回复。我现在有一个新问题。。。我已经更新了这个问题。太好了，它起作用了。我的第二个问题是，我构建了一个列表，而不是详细信息视图。感谢您的回复。我现在有一个新问题。。。我已经更新了这个问题。太好了，它起作用了。我的第二个问题是，我构建了一个列表，而不是详细信息视图。感谢您的回复。我现在有一个新问题。。。我已经更新了这个问题。太好了，它起作用了。我的第二个问题是，我构建了一个列表，而不是一个细节视图。
