 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

範例

以下範例會建立一個物件陣列 Tuple<T1,T2,T3,T4> ，其組成部分包括棒球投手的名字、投球局數，以及被擊出的安打數和自責分數。 它會以未排序順序顯示陣列中每個元組的組成部分，然後對陣列進行排序，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(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> 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> 。 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）來排序集合成員。

此 IComparable.CompareTo 方法使用預設的物件比較器來比較每個元件。
