如何使用foreach將我的屬性從模型導入到我的視圖中？

我知道我可以使用@Html.EditorFor(model => model.ID)但在我的情況下，這是不可能的，因爲我使用一個視圖爲不同的模型（從BaseModel繼承）。

型號：

public class MyModel : IEnumerable 
{ 
    private PropertyInfo[] propertys 
    { 
     get 
     { 
      if (propertys != null) return propertys; 

      string projectName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name; 
      Type classtype = Type.GetType(string.Format("{0}.Models.{1}", projectName, FQModelname)); 
      PropertyInfo[] properties = classtype.GetProperties(); 

      return properties; 
     } 
    } 

    public int ID { get; set; } 

    public string Name { get; set; } 

    //... 

    public IEnumerator GetEnumerator() 
    { 
     return propertys.GetEnumerator(); 
    } 
} 

RazorView：

@foreach (var property in Model) 
{ 
    // [Error] need Typeargument...? 
    @Html.EditorFor(property); 
}

可以這樣做更強的類型化，但是這是一個快速實現的想法，至少，你要細化一些概念併爲你的特定項目找點工作。

void Main() 
{ 
    BaseModel baseModelTest = new Concrete() { Test = "test property" }; 

    foreach (var property in baseModelTest.EnumerateProperties()) 
    { 
     var value = baseModelTest.GetPropertyValue(property.Name); 
     value.Dump(); 
    } 


} 

public class EnumeratedProperty 
{ 
    public string Name { get; private set; } 
    public Type Type { get; private set; } 
    public EnumeratedProperty(string PropertyName, Type PropertyType) 
    { 
     this.Name = PropertyName; 
     this.Type = PropertyType; 
    } 
} 

public abstract class BaseModel 
{ 
    protected IEnumerable<PropertyInfo> PropertyInfoCache { get; set; } 
    protected IEnumerable<EnumeratedProperty> EnumeratedPropertyCache { get; set; } 
    protected BaseModel() 
    { 
     PropertyInfoCache = this.GetType().GetProperties(); 
     EnumeratedPropertyCache = PropertyInfoCache.Select(p=> new EnumeratedProperty(p.Name,p.GetType())); 
    } 
    public IEnumerable<EnumeratedProperty> EnumerateProperties() 
    { 
     return EnumeratedPropertyCache; 
    } 
    public object GetPropertyValue(string PropertyName) 
    { 
     var property = PropertyInfoCache.SingleOrDefault(i=>i.Name==PropertyName); 
     if(property!=null) 
      return property.GetValue(this,null); 
     return null; 
    } 
} 

public class Concrete : BaseModel 
{ 
    public string Test { get; set; } 
} 

....

public static class ExtensionMethods 
{ 
    public static MvcHtmlString EditorForProperty(this HtmlHelper html, BaseModel Model, EnumeratedProperty property) 
    { 
     // invoke the appropriate Html.EditorFor(...) method at runtime 
     // using the type info availible in property.Type 
     return ... 
    } 
} 

....

@foreach (var property in Model.EnumerateProperties()) 
{ 
    // call the new extention method, pass the EnumeratedProperty type 
    // and the model reference 
    @Html.EditorForProperty(Model,property); 
}

你試過@Html.EditorForModel()而不是@Html.EditorFor()？
