Asp.net mvc 3 剃须刀不'；无法识别列表（）？

我的观点是这样开始的：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)

这个错误是误导性的，因为它抱怨pmodel，但它似乎不喜欢List（）

我的模型如下所示：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)

公共类placemarkkml模型
{
公共视口中心模型中心{get；set；}
公共列表KmlObjectTokens{get；set；}
}

试着这样做：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)

我猜您只是想在

pmodel

实例上分配

KmlObjectTokens

属性，在这种情况下，正确的语法是：

pmodel.KmlObjectTokens = new List<string>();

pmodel.KmlObjectTokens=new List（）；

最后一句话：视图不打算包含C代码和初始化模型。这是控制员的责任。我担心您混淆了MVC模式中的职责。

尝试如下：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)

我猜您只是想在

pmodel

实例上分配

KmlObjectTokens

属性，在这种情况下，正确的语法是：

pmodel.KmlObjectTokens = new List<string>();

pmodel.KmlObjectTokens=new List（）；

您可以绕过razor将视为HTML标记的事实，如下所示：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)

创建具有字符串列表工厂的帮助器类：

 public class Helpers
 {
    public static List<string> GetNewStringList()
    {
        return new List<string>();
    }
 }

公共类助手
{
公共静态列表GetNewStringList（）
{
返回新列表（）；
}
}

在razor视图中使用该工厂创建新的字符串列表：

@pmodel.KmlObjectTokens=Helpers.GetNewStringList（）

---

但是，正如Darin所说，您不应该在MVC模式中混用职责，因此该模型应该已经包含了用数据填充的KmlObjectTokens列表。

您可以绕过razor将视为HTML标记的事实，如下所示：

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens kmlIDs = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", @pmodel, @ViewData)

public class PlacemarkKmlModel
{
    public ViewportCenterModel Center { get; set; }

    public List<string> KmlObjectTokens { get; set; }
}

@using MyNamespace.Models.Mapping
@{
    PlacemarkKmlModel pmodel = new PlacemarkKmlModel();
    pmodel.Center.Latitude = 8.52115M;
    pmodel.Center.Longitude = -80.35981667M;
    pmodel.KmlObjectTokens = new List<string>();
    pmodel.KmlObjectTokens.Add("Sample1.kml");
    pmodel.KmlObjectTokens.Add("Sample2.kml");
}
@Html.Partial("_Mapping", pmodel, ViewData)
