RavenDB中的对象列表
本文关键字:列表 对象 RavenDB | 更新日期: 2023-09-27 17:57:57
我正在尝试在MVC项目中学习RavenDB。。。假设我们有许多文档存储在RavenDB集合中,看起来像这样:
"ShipVia": "shippers/2",
"Freight": 18.66,
"Lines": [
{
"Product": "products/25",
"ProductName": "NuNuCa Nuß-Nougat-Creme",
},
通过这样做,我成功地显示了一个单独的属性(例如"运费"):类别:
public class Orders
{
public string Freight { get; set; }
}
然后使用列表模板创建一个硬类型视图。。。这给了我数据库中所有Freights的属性。。。
我想掌握"Lines"属性,并能够看到产品和产品名称。。。尝试过这个:
namespace World.DAL
{
public class Orders
{
public string Company { get; set; }
public string Employee { get; set; }
public List<Lines> Lines { get; set; }
}
public class Lines
{
public string Product { get; set; }
public string ProductName { get; set; }
}
}
那没用。。我想刚刚返回了一个空列表。。有人能给我指正确的方向吗?
编辑:
{
"Company": "companies/65",
"Employee": "employees/5",
"OrderedAt": "1997-12-02T00:00:00.0000000",
"RequireAt": "1997-12-30T00:00:00.0000000",
"ShippedAt": "1997-12-08T00:00:00.0000000",
"ShipTo": {
"Line1": "2817 Milton Dr.",
"Line2": null,
"City": "Albuquerque",
"Region": "NM",
"PostalCode": "87110",
"Country": "USA"
},
"ShipVia": "shippers/2",
"Freight": 18.66,
"Lines": [
{
"Product": "products/25",
"ProductName": "NuNuCa Nuß-Nougat-Creme",
"PricePerUnit": 14.0,
"Quantity": 35,
"Discount": 0.25
},
{
"Product": "products/75",
"ProductName": "Rhönbräu Klosterbier",
"PricePerUnit": 7.75,
"Quantity": 18,
"Discount": 0.0
}
]
}
您的类需要与json格式完全匹配,这意味着您的类需要如下所示:
public class Orders
{
public string ShipVia { get; set; }
public string Freight { get; set; }
public List<Lines> Lines { get; set; }
}
当然,您的线路类仍然需要声明为
public class Lines
{
public string Product { get; set; }
public string ProductName { get; set; }
}
