Comentários

A MemberInfo classe é a classe base abstrata para classes usadas para obter informações sobre todos os membros de uma classe (construtores, eventos, campos, métodos e propriedades).The MemberInfo class is the abstract base class for classes used to obtain information about all members of a class (constructors, events, fields, methods, and properties).

Essa classe apresenta a funcionalidade básica que todos os membros fornecem.This class introduces the basic functionality that all members provide.

Notas aos Herdeiros

Ao herdar de MemberInfo , você deve substituir os seguintes membros GetCustomAttributes(Boolean) : IsDefined(Type, Boolean)e.When you inherit from MemberInfo you must override the following members: GetCustomAttributes(Boolean) and IsDefined(Type, Boolean).

Construtores

Métodos

Equals(Object)

Retorna um valor que indica se essa instância é igual a um objeto especificado.Returns a value that indicates whether this instance is equal to a specified object.

GetCustomAttributes(Boolean)

Quando substituído em uma classe derivada, retorna uma matriz de todos os atributos personalizados aplicados a esse membro.When overridden in a derived class, returns an array of all custom attributes applied to this member.

GetCustomAttributes(Type, Boolean)

Quando substituído em uma classe derivada, retorna uma matriz de atributos personalizados aplicados a esse membro e identificados por Type.When overridden in a derived class, returns an array of custom attributes applied to this member and identified by Type.

GetCustomAttributesData()

Retorna uma lista de objetos CustomAttributeData que representam dados sobre os atributos que foram aplicados ao membro de destino.Returns a list of CustomAttributeData objects representing data about the attributes that have been applied to the target member.

GetHashCode()

Retorna o código hash para essa instância.Returns the hash code for this instance.

GetType()
HasSameMetadataDefinitionAs(MemberInfo)
IsDefined(Type, Boolean)

Quando substituído em uma classe derivada, indica se um ou mais atributos do tipo especificado ou de seus tipos derivados são aplicados a esse membro.When overridden in a derived class, indicates whether one or more attributes of the specified type or of its derived types is applied to this member.

MemberwiseClone()

Cria uma cópia superficial do Object atual.Creates a shallow copy of the current Object.

(Herdado de Object)
ToString()

Retorna uma cadeia de caracteres que representa o objeto atual.Returns a string that represents the current object.

(Herdado de Object)

Operadores

Equality(MemberInfo, MemberInfo)

Indica se dois objetos MemberInfo são iguais.Indicates whether two MemberInfo objects are equal.

Inequality(MemberInfo, MemberInfo)

Indica se dois objetos MemberInfo não são iguais.Indicates whether two MemberInfo objects are not equal.

Implantações explícitas de interface

Mapeia um conjunto de nomes para um conjunto correspondente de identificadores de expedição.Maps a set of names to a corresponding set of dispatch identifiers.

_MemberInfo.GetType()

Obtém um objeto Type que representa a classe MemberInfo.Gets a Type object representing the MemberInfo class.

_MemberInfo.GetTypeInfo(UInt32, UInt32, IntPtr)

Recupera as informações do tipo de um objeto, que podem ser usadas para obter informações de tipo para uma interface.Retrieves the type information for an object, which can then be used to get the type information for an interface.

_MemberInfo.GetTypeInfoCount(UInt32)

Retorna o número de interfaces de informações do tipo que um objeto fornece (0 ou 1).Retrieves the number of type information interfaces that an object provides (either 0 or 1).

_MemberInfo.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
