类型参数

T1

元组的唯一一个分量的类型。The type of the tuple's only component.

继承: Object
Tuple<T1>

属性: SerializableAttribute

实现: IStructuralComparable IStructuralEquatable IComparable ITuple

注解

元组是具有特定数量和值序列的数据结构。A tuple is a data structure that has a specific number and sequence of values. Tuple<T1>类表示1元组，即单一实例，它是具有单个组件的元组。The Tuple<T1> class represents a 1-tuple, or singleton, which is a tuple that has a single component. 在应用程序开发中，单一实例相对很少使用。A singleton is used comparatively rarely in application development.

可以 Tuple<T1> 通过调用 Tuple<T1> 构造函数或静态方法来实例化对象 Tuple.Create 。You can instantiate a Tuple<T1> object by calling either the Tuple<T1> constructor or the static Tuple.Create method. 您可以使用只读实例属性检索元组的单个组件的值 Item1 。You can retrieve the value of the tuple's single component by using the read-only Item1 instance property.

构造函数

Tuple<T1>(T1)

初始化 Tuple<T1> 类的新实例。Initializes a new instance of the Tuple<T1> class.

属性

Item1

获取 Tuple<T1> 对象的单一分量的值。Gets the value of the Tuple<T1> object's single component.

方法

Equals(Object)	返回一个值，该值指示当前的 Tuple<T1> 对象是否与指定对象相等。Returns a value that indicates whether the current Tuple<T1> object is equal to a specified object.
GetHashCode()	返回当前 Tuple<T1> 对象的哈希代码。Returns the hash code for the current Tuple<T1> object.
GetType()	获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object)
ToString()	返回表示此 Tuple<T1> 实例的值的字符串。Returns a string that represents the value of this Tuple<T1> instance.

显式接口实现

IComparable.CompareTo(Object)	将当前 Tuple<T1> 对象与指定对象进行比较，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位于指定对象之前、之后还是与其位置相同。Compares the current Tuple<T1> object to a specified object, and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
IStructuralComparable.CompareTo(Object, IComparer)	使用指定的比较器将当前的 Tuple<T1> 对象与指定对象进行比较，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、之后还是与其相同。Compares the current Tuple<T1> object to a specified object by using a specified comparer, and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
IStructuralEquatable.Equals(Object, IEqualityComparer)	返回一个值，该值根据指定的比较方法指示当前的 Tuple<T1> 对象是否与指定对象相等。Returns a value that indicates whether the current Tuple<T1> object is equal to a specified object based on a specified comparison method.
IStructuralEquatable.GetHashCode(IEqualityComparer)	使用指定的计算方法计算当前 Tuple<T1> 对象的哈希代码。Calculates the hash code for the current Tuple<T1> object by using a specified computation method.
ITuple.Item[Int32]	获取 `Tuple` 元素的值。Gets the value of the `Tuple` element.
ITuple.Length	获取 `Tuple` 中的元素数。Gets the number of elements in the `Tuple`.

扩展方法

Deconstruct<T1>(Tuple<T1>, T1)	将具有 1 个元素的元组解构为不同的变量。Deconstructs a tuple with 1 element into a separate variable.
ToValueTuple<T1>(Tuple<T1>)	将 `Tuple` 类的实例转换为 `ValueTuple` 结构的实例。Converts an instance of the `Tuple` class to an instance of the `ValueTuple` structure.
