Tuple<T1,T2,T3,T4,T5>.IComparable.CompareTo(Object) 方法
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
將目前的 Tuple<T1,T2,T3,T4,T5> 物件與指定的物件比較,並傳回可指出目前物件在排序次序中,是否在指定物件之前、之後或者相同之位置的整數。
virtual int System.IComparable.CompareTo(System::Object ^ obj) = IComparable::CompareTo;
int IComparable.CompareTo (object obj);
abstract member System.IComparable.CompareTo : obj -> int
override this.System.IComparable.CompareTo : obj -> int
Function CompareTo (obj As Object) As Integer Implements IComparable.CompareTo
參數
- obj
- Object
要與目前執行個體比較的物件。
傳回
帶正負號的整數,可指出此執行個體以及排序次序中 obj
的相對位置,如下表所示。
值 | 描述 |
---|---|
負整數 | 這個執行個體位於 obj 之前。
|
零 | 這個執行個體和 obj 的排序位置相同。
|
正整數 | 這個執行個體位於 obj 之後。
|
實作
例外狀況
obj
不是 Tuple<T1,T2,T3,T4,T5> 物件。
範例
下列範例會建立物件陣列 Tuple<T1,T2,T3,T4,T5> ,其中包含在美國專業足球中回場的職涯統計資料。 這五個元件包含玩家的名稱、他播放的遊戲數目、攜帶次數或嘗試次數、取得的百分比總數,以及評分的觸控次數。 此範例會依未排序的順序顯示陣列中每個 Tuple 的元件、排序陣列,然後呼叫 ToString 以排序次序顯示每個 Tuple。 輸出顯示陣列已依名稱排序,這是第一個元件。 請注意,此範例不會直接呼叫 IComparable.CompareTo 方法。 這個方法是由 陣列中每個元素的 方法隱含 Sort(Array) 呼叫。

備註
這個成員是明確介面成員實作, 只有在 Tuple<T1,T2,T3,T4,T5> 執行個體轉換成 IComparable 介面時,才能使用這個成員。
這個方法提供 IComparable.CompareTo 類別的實作 Tuple<T1,T2,T3,T4,T5> 。 雖然可以直接呼叫 方法,但最常由集合排序方法的預設多載呼叫,例如 Array.Sort(Array) 和 SortedList.Add ,以排序集合的成員。
警告
方法 IComparable.CompareTo 適用于排序作業。 當比較的主要用途是判斷兩個物件是否相等時,就不應該使用它。 若要判斷兩個物件是否相等,請呼叫 Tuple<T1,T2,T3,T4,T5>.Equals(Object) 方法。
方法 IComparable.CompareTo(Object) 會使用預設物件比較子來比較每個元件。
