Asp.net mvc 3 如何在MVC3中使用两个IEnumerable

大家好，如何传递两个或多个IEnumerables列表以查看？这是我的动作控制器：

 ServicesClient client = new ServicesClient();
 client.ClientCredentials.UserName.UserName = "service_test";
 client.ClientCredentials.UserName.Password = "..";
            client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;

            ListCity[] city = client.GetCity();
            ListStreet[] street = client.GetStreet(2);

            return View(city);

var viewmodel = new MyViewModel{
                  City = client.GetCity(),
                  Street = client.GetStreet(2)
                };
return View(viewModel);

我的看法是：

model IEnumerable<ListCity>

@using icerik.EmlakServices 
@{

    Layout = "~/Views/Shared/Test.cshtml";
}


<select>

@foreach(var item in Model)
{

    <option>@Html.DisplayFor(x => item.CityName)</option>
}
</select>

模型IEnumerable
@使用icerik.emlak服务
@{
Layout=“~/Views/Shared/Test.cshtml”；
}
@foreach（模型中的var项目）
{
@DisplayFor（x=>item.CityName）
}

在这种情况下，您必须创建ViewModel。比如说：

public class MyViewModel{
  public ListCity[] City {get;set;}
  public ListStreet[] Street {get;set;}
}

然后在控制器中：

 ServicesClient client = new ServicesClient();
 client.ClientCredentials.UserName.UserName = "service_test";
 client.ClientCredentials.UserName.Password = "..";
            client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;

            ListCity[] city = client.GetCity();
            ListStreet[] street = client.GetStreet(2);

            return View(city);

var viewmodel = new MyViewModel{
                  City = client.GetCity(),
                  Street = client.GetStreet(2)
                };
return View(viewModel);

那么在你看来,

model MyViewModel

然后您可以在视图中获取集合，如

Model.City

，或

Model.Street

对于除基本情况外的所有情况，通常都会为几乎所有视图创建ViewModel。因此，正确地命名他们，这样你就知道他们在做什么。在这个例子中，我称它为

MyViewModel

，因为我不知道上下文

另外，我会将变量命名为

Cities

和

Streets

，因为它们是集合，而不仅仅是单个元素
