備註
在執行階段， CustomPropertyToolPart會尋找ResourcesAttribute類別。如果找到， CustomPropertyToolPart會逐一查看的LoadResource方法 (您必須覆寫這個方法) 使用ResourcesAttribute的資源值。如果找不到資源，則會將CustomPropertyToolPart使用者介面建立具有預設值。否則， CustomPropertyToolPart使用者介面是建置當地語系化的值。Microsoft.NET Framework 只會提供當地語系化值的屬性標籤、 描述及類別標籤。不會當地語系化的基底屬性名稱。如果沒有定義ResourcesAttribute類別， CustomPropertyToolPart使用者介面會回復為非當地語系化的中繼資料 (也就是CategoryAttribute、 DescriptionAttribute、 FriendlyNameAttribute和屬性的內部名稱)。
Examples
下列程式碼範例示範如何將自訂屬性時， CustomPropertyToolPart使用者介面中顯示的當地語系化。
