範例

以下範例建立了一個包含美式職業美式足球跑衛生涯統計數據的物件陣列 Tuple<T1,T2,T3,T4,T5> 。 這五個組成部分包括球員姓名、出賽場次、衝球或衝球次數、總碼數，以及達陣次數。 範例中每個元組的組成部分以未排序順序顯示，然後排序陣列，然後呼叫 ToString 以排序順序顯示每個元組。 輸出顯示陣列已依名稱排序，名稱是第一個元件。 請注意，範例中並未直接呼叫該 IComparable.CompareTo 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> 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> 。 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 IComparable.CompareTo(Object) 方法使用預設的物件比較器來比較每個元件。
