次のコード例は、実装する方法を示します、IContainerインターフェイス。The following code example demonstrates how to implement the IContainer interface.

//This code segment implements the IContainer interface.  The code segment 
//containing the implementation of ISite and IComponent can be found in the documentation
//for those interfaces.

//Implement the LibraryContainer using the IContainer interface.

class LibraryContainer : IContainer
{
	private ArrayList m_bookList;

	public LibraryContainer()
	{
		m_bookList = new ArrayList();
	}

	public virtual void Add(IComponent book)
	{
		//The book will be added without creation of the ISite object.
		m_bookList.Add(book);
	}

	public virtual void Add(IComponent book, string ISNDNNum)
	{
		for(int i =0; i < m_bookList.Count; ++i)
		{
			IComponent curObj = (IComponent)m_bookList[i];
			if(curObj.Site != null)
			{
				if(curObj.Site.Name.Equals(ISNDNNum))
					throw new ArgumentException("The ISBN number already exists in the container"); 
			}
		}

		ISBNSite data = new ISBNSite(this, book);
		data.Name = ISNDNNum;
		book.Site = data;
		m_bookList.Add(book);
	}

	public virtual void Remove(IComponent book)
	{

	}

	}

注釈

コンテナーは、カプセル化し、0 個以上のコンポーネントを追跡するオブジェクトです。Containers are objects that encapsulate and track zero or more components. このコンテキストでは、包含構造は論理的なコンテインメント、非ビジュアルの包含を示します。In this context, containment refers to logical containment, not visual containment. コンポーネントと、さまざまなビジュアルと非ビジュアルの両方であるシナリオを含むシナリオでコンテナーを使用することができます。You can use components and containers in a variety of scenarios, including scenarios that are both visual and not visual.

注意 (実装者)

コンテナーには、クラスを実装する必要があります、IContainerインターフェイスで、追加、削除、およびコンポーネントを取得するためのメソッドをサポートしています。To be a container, the class must implement the IContainer interface, which supports methods for adding, removing, and retrieving components.

プロパティ

IContainer 内のすべてのコンポーネントを取得します。Gets all the components in the IContainer.

メソッド

Add(IComponent) Add(IComponent) Add(IComponent) Add(IComponent)

指定した IComponentIContainer のリストの末尾に追加します。Adds the specified IComponent to the IContainer at the end of the list.

Add(IComponent, String) Add(IComponent, String) Add(IComponent, String) Add(IComponent, String)
