Message in Chinese (Traditional) (中文（繁體）)
無法將值新增至集合，因為集合已包含相同類型的項目: '<var>Type Name</var>'。此集合每一類型僅支援一個例項。
Unlocalized message
The value could not be added to the collection, as the collection already contains an item of the same type: '<var>Type Name</var>'. This collection only supports one instance of each type.
