下列範例示範 AddRange 類別的 方法和各種其他方法，這些方法 List<T> 會處理範圍。 字串的陣列會建立並傳遞至建構函式，以數位的元素填入清單。 系統會 AddRange 呼叫 方法，並將清單當做其自變數。 結果是清單的目前元素會新增至清單結尾，並複製所有元素。

集合中的項目順序會保留在 中 List<T>。
如果新的 Count (目前 Count 加上集合大小) 大於 Capacity，則會藉由自動重新配置內部數位以容納新元素來增加的容量 List<T> ，而現有的元素會在新增專案之前複製到新的數位。
如果 可以容納新元素而不增加 Capacity，這個方法是 o (n) 作業，其中 n 是要加入的項目數目。List<T> 如果需要增加容量以容納新的元素，這個方法會變成 O (nm) 作業，其中 n +  是要加入的項目數目，而 m 是 Count。
