Tuple<T1,T2,T3,T4,T5>.IComparable.CompareTo(Object) 方法
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
比较当前 Tuple<T1,T2,T3,T4,T5> 对象与指定对象，并返回一个整数，该整数指示当前对象在排序顺序中的位置：是在指定对象之前、之后还是在与指定对象相同的位置。
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 -> intFunction CompareTo (obj As Object) As Integer Implements IComparable.CompareTo参数
- obj
- Object
要与当前实例进行比较的对象。
返回
一个带符号整数，指示此实例和 obj 在排序顺序中的相对位置，如下表所示。
| 值 | 说明 |
|---|---|
| 负整数 | 此实例位于 obj 之前。
|
| 零 | 此实例在排序顺序中的位置与 obj 相同。
|
| 正整数 | 此实例位于 obj 之后。
|
实现
例外
obj 不是 Tuple<T1,T2,T3,T4,T5> 对象。
示例
以下示例创建一个 对象数组 Tuple<T1,T2,T3,T4,T5> ，其中包含在美国职业足球中后退的职业统计信息。 这五个组成部分包括玩家的姓名、他玩的游戏次数、携带或尝试次数、获得的总码数和得分的触地次数。 该示例按未排序顺序显示数组中每个元组的组件，对数组进行排序，然后调用 ToString 以按排序顺序显示每个元组。 输出显示数组已按名称（这是第一个组件）排序。 请注意，该示例不直接调用 IComparable.CompareTo 方法。 此方法由 Sort(Array) 数组中的每个元素的 方法隐式调用。

注解
此成员是显式接口成员的实现。 它只能在 Tuple<T1,T2,T3,T4,T5> 实例被强制转换为 IComparable 接口时使用。
此方法为 类提供 IComparable.CompareTo 实现 Tuple<T1,T2,T3,T4,T5> 。 虽然 可以直接调用 方法，但它通常由集合排序方法（如 和 SortedList.Add）Array.Sort(Array)的默认重载调用，以便对集合的成员进行排序。
注意
方法 IComparable.CompareTo 适用于排序操作。 当比较的主要目的是确定两个对象是否相等时，不应使用它。 若要确定两个 对象是否相等，请调用 Tuple<T1,T2,T3,T4,T5>.Equals(Object) 方法。
方法 IComparable.CompareTo(Object) 使用默认的对象比较器来比较每个组件。
