Como: Carregar assemblies no contexto somente reflexão

O contexto de carregamento somente reflexão permite examinar assemblies compilados para outras plataformas ou para outras versões do .NET. O código carregado neste contexto só pode ser examinado; não pode ser executado. Isso significa que os objetos não podem ser criados, porque os construtores não podem ser executados. Como o código não pode ser executado, as dependências não são carregadas automaticamente. Se você precisar examiná-los, você mesmo deve carregá-los.

Para carregar um assembly no contexto de carga somente reflexão:

  1. Use a sobrecarga de ReflectionOnlyLoad(String) método para carregar o assembly dado seu nome de exibição, ou o ReflectionOnlyLoadFrom método para carregar o assembly dado seu caminho. Se o assembly for uma imagem binária, use a sobrecarga do ReflectionOnlyLoad(Byte[]) método.

    Nota

    Você não pode usar o contexto somente reflexão para carregar uma versão do mscorlib.dll de uma versão do .NET Framework diferente da versão no contexto de execução.

  2. Se o assembly tiver dependências, o ReflectionOnlyLoad método não as carregará. Se você precisar examiná-los, você mesmo deve carregá-los.

  3. Determine se um assembly é carregado no contexto somente reflexão usando a propriedade do ReflectionOnly assembly.

  4. Se os atributos tiverem sido aplicados ao assembly ou a tipos no assembly, examine esses atributos usando a CustomAttributeData classe para garantir que nenhuma tentativa seja feita para executar código no contexto somente reflexão. Use a sobrecarga apropriada do CustomAttributeData.GetCustomAttributes método para obter CustomAttributeData objetos que representam os atributos aplicados a um assembly, membro, módulo ou parâmetro.

    Nota

    Os atributos aplicados ao assembly ou ao seu conteúdo podem ser definidos no assembly ou podem ser definidos em outro assembly carregado no contexto somente reflexão. Não há como dizer com antecedência onde os atributos estão definidos.

Exemplo

O exemplo de código a seguir mostra como examinar os atributos aplicados a um assembly carregado no contexto somente reflexão.

O exemplo de código define um atributo personalizado com dois construtores e uma propriedade. O atributo é aplicado ao assembly, a um tipo declarado no assembly, a um método do tipo e a um parâmetro do método. Quando executado, o assembly se carrega no contexto somente reflexão e exibe informações sobre os atributos personalizados que foram aplicados a ele e aos tipos e membros que ele contém.

Nota

Para simplificar o exemplo de código, o assembly carrega e examina a si mesmo. Normalmente, você não esperaria encontrar o mesmo assembly carregado no contexto de execução e no contexto somente reflexão.
