Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie sie auf AssemblyFlagsAttribute eine Assembly anwenden und wie die Flags zur Laufzeit gelesen werden. Im Beispiel wird auch eine Instanz des Attributs erstellt und die AssemblyFlags Eigenschaft verwendet, um die Flags anzuzeigen. Ein Beispiel für das Anwenden der AssemblyFlagsAttribute Eigenschaft auf eine dynamische Assembly finden Sie unter der AssemblyName.Flags Eigenschaft.

using System.Reflection;

// Specify a combination of AssemblyNameFlags for this
// assembly.

    AssemblyNameFlags.EnableJITcompileOptimizer |
    AssemblyNameFlags.Retargetable)]

        AssemblyName thisAsmName = thisAsm.GetName(false);

        // Display the flags that were set for this assembly.
        ListFlags(thisAsmName.Flags);

        // Create an instance of AssemblyFlagsAttribute with the
        // same combination of flags that was specified for this
        // assembly. Note that PublicKey is included automatically
        // for the assembly, but not for this instance of
        // AssemblyFlagsAttribute.

Hinweise

Die AssemblyNameFlags Enumeration beschreibt die Assemblymerkmale, die mithilfe dieses Attributs festgelegt werden können.

Um auf die Flags zuzugreifen, die für eine Assembly angegeben wurden, verwenden Sie die Assembly.GetName() Eigenschaft, um ein AssemblyName Objekt abzurufen, und verwenden Sie dann die AssemblyName.Flags Eigenschaft, um einen AssemblyNameFlags Wert abzurufen.

Um Flags für eine dynamische Assembly anzugeben AssemblyNameFlags , legen Sie die AssemblyName.Flags Eigenschaft des AssemblyName Objekts fest, das Sie an die AppDomain.DefineDynamicAssembly Methode übergeben.
