MVC5 Razor值不能为null或为空。参数名称:名称

源错误:第22行:@Html.TextBoxFor(型号=> model.DailyCurrencyRates\uuu Buying货币,新建{@id=“test”,@class

我在这个问题上耽搁了好几天,无法绕过这个错误。我只想呈现一个包含父类项的部分视图。以下是我的代码:如果需要,请询问更多信息。

public ActionResult AddRecord(int index)
{
  return PartialView("_AddItem", new ForexItem { Index = index});
}

父视图

@foreach (ForexItem item in Model.ForexItems)
{
    Html.RenderPartial("_AddItem", item);
}

局部视图

@model F.Models.Entities.ForexItem

@Html.TextBoxFor(model => model.DailyCurrencyRates___BuyingCurrency, new { @id = "test", @class = "form-control" })

模型

public partial class ForexItem
 {
        public int ID { get; set; }

        [NotMapped]
        [StringLength(1000)]
        [Display(Name = "Buying")]
        public string DailyCurrencyRates___BuyingCurrency { get; set; }

        [NotMapped]
        public int Index { get; set; }
}
