Tuple<T1,T2,T3,T4,T5,T6>.Equals(Object) 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Tuple.cs

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

public:
 override bool Equals(System::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。

返回

Boolean

如果当前实例等于指定对象，则为 true；否则为 false。

示例

以下示例定义一个包含 1960 年到 2000 年洛杉矶和纽约人口数据的性别数组。 每个性别的第一个部分标识城市。 第一、第三和第四个性别者包含纽约的数据。 第一个性别是第四个性别的重复项。 第三个性别将城市标识为“纽约市”，而不是“纽约”。 如示例所示，只有第四个性交等于第一个性别。

注解

在 obj 以下条件下， 参数被视为等于当前实例：

• 它是一个 Tuple<T1,T2,T3,T4,T5,T6> 对象。

• 其六个组件的类型与当前实例的类型相同。

• 其六个组件等于当前实例的组件。 相等性取决于每个组件的默认对象相等比较器。
