呈现在asp.net C＃MVC局部视图或行动

Question

我有以下型号：

public partial class CityMaster 
{ 
    public int id { get; set; } 
    public string cityname { get; set; } 
} 

public partial class CityJourny 
{ 
    public int journyId { get; set; } 
    public int fromCity { get; set; } //foreign key from citymaster 
    public int ToCity { get; set; } //foreign key from citymaster 
    public string description { get; set; } 
    public string distance { get; set; } 
} 

//View model 
public partial class VMCity 
{ 
    public CityMaster cm { get; set; } 
    public List<CityJourny> cj { get; set; } 
} 

cityview.cshtml：

@model APIModels.UserModel.VMCity 

@{ 
    ViewBag.Title = "View1"; 
} 

<h2>View1</h2> 

<fieldset> 
    <legend>VMCity</legend> 
    @Html.DisplayFor(model => model.cm.cityname) 

    @* hear I would like to display list of city from city *@ 
    @Html.Partial("Partial1",new APIModels.UserModel.VMCity()); 
</fieldset> 
<p> 
    @Html.ActionLink("Edit", "Edit", new { /* id=Model.PrimaryKey */ }) | 
    @Html.ActionLink("Back to List", "Index") 
</p> 

我应该在我的控制器行动写入显示城市数据和城市距离列表（我们提供从一个城市到其他城市的巴士服务）

不要在您的视图模型上调用new，因为这会导致使用新的空模型。

你还是使用

@Html.Partial("Partial1", @Model.APIModels.UserModel.{Name of your collection containing the cities});

或者，如果该部分只是显示一个城市，你需要遍历你的城市景观

@foreach (var city in YOUR_CITY_COLLECTION_HERE) { @Html.Partial("Partial1", city); }
