Przykłady

Ta sekcja zawiera dwa przykłady kodu. Pierwszy pokazuje, jak deklaratywnie określać wartości dla kilku właściwości AssemblyCollection klasy. Drugi pokazuje, jak używać składowych AssemblyCollection klasy.

Poniższy przykładowy plik konfiguracji przedstawia sposób deklaratywnego określania wartości dla kilku właściwości AssemblyCollection klasy.

<system.web>
  <compilation>
    <assemblies>
      <add assembly="mscorlib" />
      <add assembly="System, Version=2.0.0.0, Culture=neutral,

      <add assembly="System.Drawing, Version=2.0.0.0,
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.EnterpriseServices, Version=2.0.0.0,
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.Web.Mobile, Version=2.0.0.0,
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.Web.UI.MobileControls.Adapters,

W poniższym przykładzie kodu pokazano, jak używać składowych AssemblyCollection klasy.

Uwagi

Klasa AssemblyCollection nie odwołuje się do żadnego rzeczywistego elementu w bazowym pliku konfiguracji. Jest to konstrukcja, która umożliwia dostęp do zawartych w nim informacji o zestawie.
