備註

Values使用 屬性來存取插入記錄的欄位值。 例如,您可以使用這些值來保留插入記錄的記錄。

屬性會 Values 傳回實 OrderedDictionary 作 介面的物件 System.Collections.Specialized.IOrderedDictionary 。 物件 OrderedDictionary 包含 System.Collections.DictionaryEntry 代表插入記錄欄位的物件。 若要存取功能變數名稱,請使用 Keys 物件的 OrderedDictionary 屬性。 同樣地,您可以使用 屬性來存取域值 Values

注意

做為快捷方式,您也可以使用 物件的索引子 OrderedDictionary 直接存取域值。 使用索引子的優點是它會直接傳回域值。 依賴欄位順序的資料來源控制項 (,例如 AccessDataSource) 只能依索引存取域值。
