範例

以下範例建立一個八元組陣列，其組成部分為整數，包含一組質數範圍。 範例中先以未排序順序顯示陣列元素，先排序陣列，然後再以排序順序顯示陣列。 輸出顯示陣列已被排序為 Item1，也就是元組的第一個分量。 請注意，範例中並未直接呼叫該 IComparable.CompareTo(Object) 方法。 此方法由 方法 Sort(Array) 隱含呼叫，針對陣列中的每個元素。

備註

此成員為明確介面成員實作。 它只能在實 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 例投射到 IComparable 介面時使用。

此方法提供 IComparable.CompareTo 類別的實作 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 。 雖然此方法可直接呼叫，但通常由預設的集合排序方法（如 Array.Sort(Array) 和 SortedList.Add）呼叫，以排序集合成員。

此方法使用預設物件比較器來比較每個元件。
