使用通用列表作为属性

问题描述

大家好，

我试图在Code Project上寻找解决方案，但没有找到解决方案.因此，如果以前曾问过这个问题，请指出正确的方向.

好的，所以我试图在VS2010中使用C#实现复合设计模式结构.

首先，我使用的设计模式并不重要，但是我很好奇的是VS2010及其从我的结构生成的类图.

我创建了一个抽象的Component类，并让Composite类从中继承.我还具有从抽象的Component Class继承的Leaf Class.

为了在Component和Composite之间进行简单的聚合，可以使用ArrayList，但是我选择了通用列表.组件

.因此，现在我可以使用

  public   void  addChild(Component childComponent) 

将子级添加到我的Composite中.这有效并且很酷.但是我注意到(在VS2010中生成类图时)，没有箭头(聚集)从Composite指向我的组件类.通过使用

List<Component> component

确实存在聚合.

然后，如果我继续并绘制从Composite到Component的聚合，则会在我的Composite类中生成以下代码:

  public 组件组件
{
    获取
    {
        抛出 新 System.NotImplementedException();
    }
    设置
    {
    }
}

所以，最后是我的问题:您如何将生成的代码与List< t>一起使用.甚至有必要为此担心吗?

解决方案

Hi all,

I tried to look for a solution on this on Code Project, but found none. So if this question has been asked before, please point me in the right direction.

Ok, so I am trying to implement a Composite Design Pattern structure using C# in VS2010.

Firstly, what I''m using the design pattern for is not important, but what I am curious about is VS2010 an its Class Diagrams that it generate from my structure.

I created an abstract Component Class and have the Composite Class inheriting from that. I also have the Leaf Class inheriting from the abstract Component Class.

For a simple aggregation between Component and Composite, one can use an ArrayList, but I opted for a generic list

List<Component> component

. So now I can use a method

public void addChild(Component childComponent)

to add children to my Composite. This works and is cool. But I noticed (when generating a class diagram in VS2010) that there is no arrow (aggregation) pointing to my Component Class from Composite. An aggregation does exist through the use of my

List<Component> component

.

If I then continue and draw an aggregation from Composite to Component, the following code is generated in my Composite Class:

public Component Component
{
    get
    {
        throw new System.NotImplementedException();
    }
    set
    {
    }
}

So, finally my question: How would you use this generated code with a List<t>. Is it even necessary to worry about this?

Thanks in advance.
