CustomAttributeData.ConstructorArguments Propriedade

Definição

Namespace:

System.Reflection

Assembly:

System.Runtime.dll

Origem:

CustomAttributeData.cs

Obtém a lista de argumentos posicionais especificados para a instância de atributo representada pelo objeto CustomAttributeData.

public:
 virtual property System::Collections::Generic::IList<System::Reflection::CustomAttributeTypedArgument> ^ ConstructorArguments { System::Collections::Generic::IList<System::Reflection::CustomAttributeTypedArgument> ^ get(); };

public virtual System.Collections.Generic.IList<System.Reflection.CustomAttributeTypedArgument> ConstructorArguments { get; }

member this.ConstructorArguments : System.Collections.Generic.IList<System.Reflection.CustomAttributeTypedArgument>

Public Overridable ReadOnly Property ConstructorArguments As IList(Of CustomAttributeTypedArgument)

Valor da propriedade

IList<CustomAttributeTypedArgument>

Uma coleção de estruturas que representa os argumentos posicionais especificados para a instância de atributo personalizado.

Exemplos

O exemplo a seguir define um atributo personalizado com quatro construtores e quatro propriedades. Duas das propriedades são somente leitura e são definidas usando os parâmetros posicionais dos construtores. As outras duas propriedades são leitura/gravação e só podem ser definidas usando argumentos nomeados. Uma propriedade posicional é uma matriz de cadeias de caracteres e uma propriedade nomeada é uma matriz de inteiros.

O atributo é aplicado ao assembly, a um tipo declarado no assembly, para um método do tipo e a um parâmetro do método. Construtores diferentes são usados para esses casos. Quando executado, o assembly é carregado no contexto somente reflexão e exibe os atributos personalizados.

O atributo aplicado ao tipo demonstra as propriedades da matriz, com argumentos posicionais e nomeados.

A ConstructorArguments propriedade é usada no ShowAttributeData método que exibe dados de atributo personalizados. Neste exemplo de código, essa propriedade é usada para exibir a lista de argumentos passados para o construtor que inicializou o atributo.

Comentários

Esse método obtém os argumentos posicionais que foram especificados para a instância de atributo personalizado sem executar nenhum código de atributo personalizado. Assim, ele pode ser usado no contexto somente reflexão.

Use o NamedArguments método para obter os argumentos nomeados especificados para a instância de atributo.
