ZipPackage 類別
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
實作抽象 Package 基底類別的衍生子類別,ZipPackage 類別使用 ZIP 封存檔作為容器存放區。 此類別無法獲得繼承。
public ref class ZipPackage sealed : System::IO::Packaging::Package
public sealed class ZipPackage : System.IO.Packaging.Package
type ZipPackage = class
inherit Package
Public NotInheritable Class ZipPackage
Inherits Package

範例
此範例示範如何建立基本 ZipPackage。
此範例會建立包含單一檔元件的套件,該元件是由封裝層級 PackageRelationship定義為封裝的根元素。
套件也包含影像元件,第二 PackageRelationship 個元件會定義源文檔元件與目標影像元件之間的關聯。 (影像是與檔) 搭配使用的資源。
