Exemplos

O exemplo de código seguinte mostra como aplicar o AssemblyFlagsAttribute a um assembly e como ler as flags em tempo de execução. O exemplo também cria uma instância do atributo e usa a AssemblyFlags propriedade para mostrar as bandeiras. Para um exemplo de como aplicar o AssemblyFlagsAttribute a um conjunto dinâmico, veja a AssemblyName.Flags propriedade.

using System;
using System.Reflection;

// Specify a combination of AssemblyNameFlags for this
// assembly.
[assembly:AssemblyFlagsAttribute(
    AssemblyNameFlags.EnableJITcompileOptimizer |
    AssemblyNameFlags.Retargetable)]

public class Example
{
    public static void Main()
    {
        // Get this assembly.
        Assembly thisAsm = typeof(Example).Assembly;

        // Get the AssemblyName for this assembly.
        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.
        AssemblyFlagsAttribute afa = new AssemblyFlagsAttribute(
            AssemblyNameFlags.EnableJITcompileOptimizer |
            AssemblyNameFlags.Retargetable);

        // Get the flags. The property returns an integer, so
        // the return value must be cast to AssemblyNameFlags.
        AssemblyNameFlags anf = (AssemblyNameFlags) afa.AssemblyFlags;

        // Display the flags.
        Console.WriteLine();
        ListFlags(anf);
    }

    private static void ListFlags(AssemblyNameFlags anf)
    {
        if (anf == AssemblyNameFlags.None)
        {
            Console.WriteLine("AssemblyNameFlags.None");
        }
        else
        {
            if (0!=(anf & AssemblyNameFlags.Retargetable))
                Console.WriteLine("AssemblyNameFlags.Retargetable");
            if (0!=(anf & AssemblyNameFlags.PublicKey))
                Console.WriteLine("AssemblyNameFlags.PublicKey");

                Console.WriteLine("AssemblyNameFlags.EnableJITcompileTracking");
        }
    }

Observações

A AssemblyNameFlags enumeração descreve as características de montagem que podem ser definidas usando este atributo.

Para aceder aos flags especificados para uma montagem, use a Assembly.GetName() propriedade para obter um AssemblyName objeto e depois use a AssemblyName.Flags propriedade para obter um AssemblyNameFlags valor.

Para especificar AssemblyNameFlags flags para uma montagem dinâmica, defina a AssemblyName.Flags propriedade do AssemblyName objeto que passa para o AppDomain.DefineDynamicAssembly método.
