Question

我遇到的问题是只将第一个界面投射到Javascript。我想知道是否有任何解决方法/解决方法。

我想在Javascript中访问大约20个类。这20个类继承自BaseModel，它包含所有20个类都很重要的代码。以下是一个简单的例子：

public class Category : BaseModel
{
    public string Title {get;set;}
    public string Description {get;set;}
}

public class Item : BaseModel
{
    public string Title {get;set;}
    public string Price {get;set;}
}

public class BaseModel : INotifyPropertyChanged, IParentableViewModel
{
    //Some Important Methods that are shared between around 20 Models
}

如果我想在Javascript中访问它，我将不得不为所有20个类创建BaseModel。这是因为Javascript只能看到第一个接口的属性/方法。那么我的代码就变成了：

public class CategoryBaseModel : ICategoryModel, INotifyPropertyChanged, IParentableViewModel
{
    //Important Methods gets duplicated between CategoryBaseModel and ItemBaseModel making it harder to maintain
}

public class ItemBaseModel : IItemModel, INotifyPropertyChanged, IParentableViewModel
{
    //Important Methods gets duplicated between CategoryBaseModel and ItemBaseModel making it harder to maintain
}

这很难维护，特别是因为我有大约20种方法。

我正在寻找是否可以覆盖Javascript的setter但不知道该怎么做。这个想法是这样的：

//I want to override something like this. 
//whenever I call category.someProperty = someValue; in Javascript, it goes through this.
//When it goes through this, I can then call the SetProperty method for unknown properties in the interface
public bool JavaScriptPropertySet(object, propertyName, Value)
{
    if(object.hasProperty(propertyName))
    {
        //Set PropertyName
    }
    else
    {
        object.setProperty(propertyName, Value);
    }
}

然后我可以将我的类定义为更简单：

public interface IBaseViewModel
{
    string Title {get;set;}
    void SetProperty(propertyName, Value);
}

public class BaseModel : IBaseViewModel, INotifyPropertyChanged, IParentableViewModel
{
    //important methods

    public void SetProperty(propertyName, Value)
    {
        SetPropertyInternal(propertyName, Value);
    }

    public virtual void SetPropertyInternal(propertyName, Value)
    {
    }
}

public class Category : BaseModel
{
    public override void SetPropertyInternal(propertyName, Value)
    {
        if(propertyName == 'description')
            this.description = Value;
    }
}

有这样的方法吗？

谢谢
