Question

我有一个类似的模型：

 public class PurchaseOrderPreliminaryCSVModel
    {
        public string Item1 { get; set; }
        public string Item2 { get; set; }
        public string Item3 { get; set; }
        public string Item4 { get; set; }
        public IList<PreliminaryPurchaseOrderDesignNameViewModel> PreliminaryDesignNames { get; set; } = new List<PreliminaryPurchaseOrderDesignNameViewModel>();

        public class PreliminaryPurchaseOrderDesignNameViewModel
        {
            public List<IEnumerable> DesignName { get; set; }
        }
    }

所以我将项目对象填充为：

List<PurchaseOrderPreliminaryCSVModel> result = new List<PurchaseOrderPreliminaryCSVModel>();
 try
            {
                if (Path.GetExtension(fileName).Equals(".csv"))
                {
                    using (MemoryStream memory = new MemoryStream(model.PreliminaryFile.File))
                    {
                        using (var reader = new StreamReader(memory))

                        using (var csv = new CsvReader(reader))
                        {
                            var record = new PurchaseOrderPreliminaryCSVModel();
                            var records = csv.EnumerateRecords(record);

                            foreach (var r in records)
                            {
                                PurchaseOrderPreliminaryCSVModel tempResult = new PurchaseOrderPreliminaryCSVModel
                                {
                                    Item1 = r.Item1,
                                    Item2 = r.Item2,
                                    Item3 = r.Item3,
                                    Item4 = r.Item4,
                                };
                                result.Add(tempResult);
                            }
                        }
                    }

因此，我将ViewModel列表放入了另一个我执行的方法中：

var designNames = _purchaseOrderRepository.GetPreliminaryDesignNames(fileName);

我的问题是：如何将模型PreliminaryDesignNames { get; set; }填充到foreach中，就像这样：

result.Add(designNames);

但是指定填充该视图模型。我怎样才能做到这一点？问候

您可以使用. operator从 PurchaseOrderPreliminaryCSVModel 类型（代码中的tempResult）的实例访问 PreliminaryDesignNames 属性

...
foreach (var r in records)
{
    PurchaseOrderPreliminaryCSVModel tempResult = new PurchaseOrderPreliminaryCSVModel
    {
        Item1 = r.Item1,
        Item2 = r.Item2,
        Item3 = r.Item3,
        Item4 = r.Item4,
    };
    var designNames = _purchaseOrderRepository.GetPreliminaryDesignNames(fileName);
    tempResult.PreliminaryDesignNames.AddRange(designNames);
    result.Add(tempResult);
}
...

填充其他属性后填充视图模型
