首先我对MVC 3方法很陌生,所以请不要对我很难。我尝试使用模型绑定,以及具有另一个模型列表的模型。此模型的属性成功绑定,但列表不。模型绑定不适用于我 - MVC 3
这里是类:
public class Company
{
public int Id { get; set; }
public String Name { get; set; }
public List<Address> Addresses { get; set; }
}
public class Address
{
public int Id { get; set; }
public String Street { get; set; }
}
这是我的模型:
public class CompanyDetailsModel
{
public Classes.Company Company { get; set; }
public List<Address> Addressess { get; set; }
}
我控制器(GET)
public ActionResult Create()
{
var model = new CompanyDetailsModel();
model.Addressess = new List<Address>();
//Just for this example like this
model.Addressess.Add(new Address());
model.Addressess.Add(new Address());
return View(model);
}
我控制器(POST)
[HttpPost]
public ActionResult Create(CompanyDetailsModel CompanyDetailsModel)
{
foreach (var address in CompanyDetailsModel.Addressess)
{
//logic
}
return View();
}
检视:
(当然也导入的模型)
形式内:
foreach (var address in Model.Addressess) { <fieldset> <legend>Test</legend> @Html.EditorFor(model => address.Street) </fieldset> }
错误: [NullReferenceException异常:对象没有设置的一个实例对象。]
额外信息:我可以保存公司的所有属性,没有任何问题,使用山姆e CompanyDetailsModel。
我希望有人能帮助我/指引我走向正确的方向。
在此先感谢

我很抱歉,但我并不完全明白你的意思。你能解释一下吗?我不知道如果我解释好,但错误是在后控制器.. – Gyocol
哦确定...你发布异常的堆栈跟踪? – Ankur
是的,当然,我正在查找如何正确添加堆栈跟踪到我的问题...找不到它大声笑,在此先感谢 – Gyocol
