Type.IsMarshalByRef Propriedade

Definição

Obtém um valor que indica se é realizado marshal no Type por referência.Gets a value indicating whether the Type is marshaled by reference.

public:
 property bool IsMarshalByRef { bool get(); };
public bool IsMarshalByRef { get; }
member this.IsMarshalByRef : bool
Public ReadOnly Property IsMarshalByRef As Boolean

Valor da propriedade

true se for realizado marshal no Type por referência; caso contrário, false.true if the Type is marshaled by reference; otherwise, false.

Exemplos

O exemplo a seguir demonstra as propriedades IsContextful, IsMarshalByRefe IsPrimitive da classe Type.The following example demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties of the Type class. Ele verifica se o tipo fornecido pode ser hospedado no contexto, se ele pode ser empacotado por referência e se o tipo é um tipo de dados primitivo.It checks whether the given type can be hosted in the context, whether it can be marshaled by reference, and whether the type is a primitive data type.
