屬性在邏輯上與欄位相同。 屬性是物件的狀態具名層面,其值通常可透過 get
和 set
存取子存取。 屬性可以是唯讀的,在此情況下不支援集合例程。
若要判斷屬性是否為 static
,您必須呼叫 GetGetMethod 或 方法來取得 MethodInfoget
或 set
存取子的 GetSetMethod ,並檢查其 IsStatic 屬性。
這個類別中的數個方法假設 get
屬性的存取子和 set
存取子方法具有特定格式。 和 set
方法的get
簽章必須符合下列慣例:
方法的 get
傳回型別和方法的最後一個自變數 set
必須相同。 這是屬性的類型。
get
和 set
方法必須具有相同的索引數目、類型和順序。
如果未遵循此格式,則 和 SetValue
方法的行為GetValue
是未定義的。
PropertyInfo
當 的 inherit
true
GetCustomAttributes
參數未逐步執行型別階層時,呼叫 。ICustomAttributeProvider.GetCustomAttributes 使用 System.Attribute 來繼承自定義屬性。
給實施者的注意事項
當您繼承自 PropertyInfo時,必須覆寫下列成員: GetValue(Object, Object[])、 SetValue(Object, Object, BindingFlags, Binder, Object[], CultureInfo)、 GetAccessors(Boolean)、 GetGetMethod(Boolean)、 GetSetMethod(Boolean)、 和 GetIndexParameters()。
