備註
類別 MemberInfo 是類別的抽象基類，可用來取得類別的所有成員相關資訊， (建構函式、事件、欄位、方法和屬性) 。
這個類別介紹所有成員提供的基本功能。
給實施者的注意事項
當您繼承自 MemberInfo 時，必須覆寫下列成員： GetCustomAttributes(Boolean) 和 IsDefined(Type, Boolean) 。
建構函式
| MemberInfo() |
初始化 MemberInfo 類別的新執行個體。 |
屬性
| CustomAttributes |
取得包含此成員之自訂屬性的集合。 |
| DeclaringType |
取得宣告這個成員的類別。 |
| 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。 |
| 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。 |
| MetadataToken |
取得值，這個值可識別中繼資料項目。 |
| 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。 |
| Name |
取得目前成員的名稱。 |
| ReflectedType |
取得類別物件，是用來取得這個 |
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。 |
| Equals(Object) |
判斷指定的物件是否等於目前的物件。 (繼承來源 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。 |
| 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。 |
| 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。 |
| GetHashCode() |
傳回這個執行個體的雜湊碼。 |
| GetHashCode() |
做為預設雜湊函式。 (繼承來源 Object) |
| GetType() |
探索成員的屬性並提供成員中繼資料的存取。 |
| GetType() |
取得目前執行個體的 Type。 (繼承來源 Object) |
| HasSameMetadataDefinitionAs(MemberInfo) |
取得成員的屬性相關資訊，並提供成員中繼資料的存取。 |
| 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。 |
| MemberwiseClone() |
建立目前 Object 的淺層複製。 (繼承來源 Object) |
| ToString() |
傳回代表目前物件的字串。 (繼承來源 Object) |
運算子
| Equality(MemberInfo, MemberInfo) |
表示兩個 MemberInfo 物件是否相等。 |
| Inequality(MemberInfo, MemberInfo) |
表示兩個 MemberInfo 物件是否不相等。 |
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)。 |
| _MemberInfo.GetType() |
取得 Type 物件，表示 MemberInfo 類別。 |
| _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。 |
| _MemberInfo.GetTypeInfoCount(UInt32) |
擷取物件提供的類型資訊介面數目 (0 或 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。 |
| ICustomAttributeProvider.GetCustomAttributes(Boolean) |
傳回這個成員中定義的所有自訂屬性的陣列 (但具名屬性除外)，如果沒有自訂屬性，則傳回空陣列。 |
| ICustomAttributeProvider.GetCustomAttributes(Type, Boolean) |
傳回這個成員中定義的自訂屬性陣列 (依類型識別)，如果沒有該類型的自訂屬性，則傳回空陣列。 |
| ICustomAttributeProvider.IsDefined(Type, Boolean) |
指出此成員上是否有定義一個或多個 |
擴充方法
| GetCustomAttribute(MemberInfo, Type) |
擷取指定型別的自訂屬性，此屬性套用至指定成員。 |
| GetCustomAttribute(MemberInfo, Type, Boolean) |
擷取只訂型別的自訂屬性，此屬性套用至指定成員，並且可選擇性檢查該成員的祖系。 |
| GetCustomAttribute<T>(MemberInfo) |
擷取指定型別的自訂屬性，此屬性套用至指定成員。 |
| GetCustomAttribute<T>(MemberInfo, Boolean) |
擷取只訂型別的自訂屬性，此屬性套用至指定成員，並且可選擇性檢查該成員的祖系。 |
| GetCustomAttributes(MemberInfo) |
擷取套用至指定成員的自訂屬性集合。 |
| GetCustomAttributes(MemberInfo, Boolean) |
擷取自訂屬性集合，此集合套用至指定成員，並且可選擇性檢查該成員的祖系。 |
| GetCustomAttributes(MemberInfo, Type) |
擷取指定型別的自訂屬性集合，此集合套用至指定成員。 |
| GetCustomAttributes(MemberInfo, Type, Boolean) |
擷取指定型別的自訂屬性集合，此集合套用至指定成員，並且可選擇性檢查該成員的祖系。 |
| GetCustomAttributes<T>(MemberInfo) |
擷取指定型別的自訂屬性集合，此集合套用至指定成員。 |
| GetCustomAttributes<T>(MemberInfo, Boolean) |
擷取指定型別的自訂屬性集合，此集合套用至指定成員，並且可選擇性檢查該成員的祖系。 |
| IsDefined(MemberInfo, Type) |
指出是否將所指定型別的自訂屬性套用至指定的成員。 |
| IsDefined(MemberInfo, Type, Boolean) |
指出指定之型別的自訂屬性是否會套用至指定的成員，以及選擇性地套用到其上階。 |
| GetMetadataToken(MemberInfo) |
取得指定成員的中繼資料語彙基元 (如果有)。 |
| HasMetadataToken(MemberInfo) |
傳回值，指出所指定成員是否有可用的中繼資料語彙基元。 |
