備註

MemberInfo類別是類別的抽象基類,可用來取得類別的所有成員(程式、事件、欄位、方法和屬性)的相關資訊。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).

這個類別會介紹所有成員所提供的基本功能。This class introduces the basic functionality that all members provide.

給繼承者的注意事項

當您繼承自MemberInfo時,您必須覆寫下列GetCustomAttributes(Boolean)成員IsDefined(Type, Boolean):和。When you inherit from MemberInfo you must override the following members: GetCustomAttributes(Boolean) and IsDefined(Type, Boolean).

建構函式

MemberInfo()

初始化 MemberInfo 類別的新執行個體。Initializes a new instance of the MemberInfo class.

屬性

CustomAttributes

取得包含此成員之自訂屬性的集合。Gets a collection that contains this member's custom attributes.

DeclaringType

取得宣告這個成員的類別。Gets the class that declares this member.

IsCollectible

取得指出此 MemberInfo 物件是否為可回收 AssemblyLoadContext 中保存之組件一部分的值。Gets a value that indicates whether this MemberInfo object is part of an assembly held in a collectible AssemblyLoadContext.

MemberType

在衍生類別中覆寫時,取得 MemberTypes 值,指出成員類型︰方法、建構函式、事件等。When overridden in a derived class, gets a MemberTypes value indicating the type of the member - method, constructor, event, and so on.

MetadataToken

取得值,這個值可識別中繼資料項目。Gets a value that identifies a metadata element.

Module

取得用於定義型別的模組,該型別宣告以目前 MemberInfo 表示的成員。Gets the module in which the type that declares the member represented by the current MemberInfo is defined.

Name

取得目前成員的名稱。Gets the name of the current member.

ReflectedType

取得類別物件,是用來取得這個 MemberInfo 的執行個體。Gets the class object that was used to obtain this instance of MemberInfo.

方法

Equals(Object)

傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object.

GetCustomAttributes(Boolean)

在衍生類別中覆寫時,傳回套用至此成員之所有自訂屬性的陣列。When overridden in a derived class, returns an array of all custom attributes applied to this member.

GetCustomAttributes(Type, Boolean)

當在衍生的類別中覆寫時,會傳回套用至這個成員的自訂屬性陣列,並以 Type 識別。When overridden in a derived class, returns an array of custom attributes applied to this member and identified by Type.

GetCustomAttributesData()

傳回 CustomAttributeData 物件的清單,表示已套用至目標成員之屬性的資料。Returns a list of CustomAttributeData objects representing data about the attributes that have been applied to the target member.

GetHashCode()

傳回這個執行個體的雜湊碼。Returns the hash code for this instance.

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

在衍生類別中覆寫時,表示是否已有一個或多個具有指定型別或其衍生型別的屬性套用至這個成員。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()

建立目前 Object 的淺層複本 (Shallow Copy)。Creates a shallow copy of the current Object.

(繼承來源 Object)
ToString()

傳回代表目前物件的字串。Returns a string that represents the current object.

(繼承來源 Object)

運算子

Equality(MemberInfo, MemberInfo)

表示兩個 MemberInfo 物件是否相等。Indicates whether two MemberInfo objects are equal.

Inequality(MemberInfo, MemberInfo)

表示兩個 MemberInfo 物件是否不相等。Indicates whether two MemberInfo objects are not equal.

明確介面實作

_MemberInfo.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

_MemberInfo.GetType()

取得 Type 物件,表示 MemberInfo 類別。Gets a Type object representing the MemberInfo class.

_MemberInfo.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can then be used to get the type information for an interface.

_MemberInfo.GetTypeInfoCount(UInt32)

擷取物件提供的類型資訊介面數目 (0 或 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)

提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object.

ICustomAttributeProvider.GetCustomAttributes(Boolean)
ICustomAttributeProvider.GetCustomAttributes(Type, Boolean)
ICustomAttributeProvider.IsDefined(Type, Boolean)
