C# 列表（型号）工厂中的列表

我想在数据列表中创建数据列表。我相信这很难解释，但我会尽量把我的问题解释清楚。我创建了数据列表，但在此列表中，一些参数也是数据列表。我必须使用此代码编写，因为这是限制（我们的工厂）。如果我获取的数据不是数据列表，那么一切都正常。问题在哪里？若我在列表中写入列表，我会得到错误。也许你能看出我的错误

程序是可编译的

问题（我使用NHibernate中的映射从第三个表中获取数据）：

重要：

public IEnumerable<DictionaryListModel> OnList(DictionayDisplayModel dictionary DisplayModel, int jtStartIndex = 0, int jtPageSize = 0, string jtSorting = null)
{
var displayModel = (DictionaryNewInfoDisplayModel)dictionaryDisplayModel;
if (displayModel == null)

var list = _dictImportantInformation.GetList().Select(
x=> new DictionaryNewInfoListModel
    {
        Id = x.Id
        Description = x.Description,
        IsActiveYN = x.IsActive,
        DestynationName = (List<DictionaryNewInfoSupportList>) x.DictImportantInformationXDestination.Select(n => new DictionaryNewInfoSupportList 
        { Id = n.Destination.Id, Name = Destination.Description}).To.List()
    }
    ).ToList();

return list;

}

将此作为答案并接受它，关闭主题的最佳方式请按照@dove request的程序进行。这个问题仍然没有回答，但你自己回答了（这很好）。因此，点击“回答你自己的问题”，将其添加为答案，两天后（我认为）你将能够接受它作为答案并将其从列表中删除。

public Ilist<dictionaryNewInfoSupportList> DestynationName;

class dictionaryNewInfoSupportList
{
public string Name {get; set;}
public int Id {get; set;}
}

public IEnumerable<DictionaryListModel> OnList(DictionayDisplayModel dictionary DisplayModel, int jtStartIndex = 0, int jtPageSize = 0, string jtSorting = null)
{
var displayModel = (DictionaryNewInfoDisplayModel)dictionaryDisplayModel;
if (displayModel == null)

var list = _dictImportantInformation.GetList().Select(
x=> new DictionaryNewInfoListModel
    {
        Id = x.Id
        Description = x.Description,
        IsActiveYN = x.IsActive,
        DestynationName = (List<DictionaryNewInfoSupportList>) x.DictImportantInformationXDestination.Select(n => new DictionaryNewInfoSupportList 
        { Id = n.Destination.Id, Name = Destination.Description}).To.List()
    }
    ).ToList();

return list;

}

var list = _dictImportantInformation.GetList().ToList().Select(
            x => new DictionaryNewInfoListModel
                     {
                         Id = x.Id,
                         Description = x.Description,
                         IsActiveYN = x.IsActive,
                         DeestynationName = x.DictImportantInformationXDestination.Select(n => new DictionaryNewInfoSupportList 
                         { Id = n.Destination.Id, Name = n.Destination.Description }).ToList()
                     }

            ).ToList();

var list = _dictImportantInformation.GetList().ToList().Select(
            x => new DictionaryNewInfoListModel
                     {
                         Id = x.Id,
                         Description = x.Description,

                     }

            ).ToList();
