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。

返回一个值，该值指示当前的 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 对象是否与指定对象相等。

public:
 override bool Equals(System::Object ^ obj);

public override bool Equals (object obj);

public override bool Equals (object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

参数

obj: Object

与该实例进行比较的对象。

Boolean

如果当前实例等于指定对象，则为 true；否则为 false。

示例

以下示例定义包含质数的五 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 个对象。然后，它将第一个对象与其余每个对象进行比较。正如输出所示，只有第一个和最后 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 一个对象是相等的，因为它们具有具有相同值的组件数。

注解

obj如果参数满足以下所有条件，则参数被视为等于当前实例：

它是一个 Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> 对象。
它的组件总数与当前实例的类型相同。
其组件 (包括其嵌套组件) 等于当前实例的组件。相等性由每个组件的默认相等比较器确定。
