屬性

備註

EditableAttribute 資料欄位上的屬性存在時,會指出使用者是否應該能夠變更欄位的值。The presence of the EditableAttribute attribute on a data field indicates whether the user should be able to change the field's value.

這個類別不會強制執行,也不保證欄位是可編輯的。This class neither enforces nor guarantees that a field is editable. 無論這個屬性的存在與否,基礎資料存放區都可以讓欄位變更。The underlying data store might allow the field to be changed regardless of the presence of this attribute.
