ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>.IStructuralEquatable.Equals(Object, IEqualityComparer) ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>.IStructuralEquatable.Equals(Object, IEqualityComparer) ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>.IStructuralEquatable.Equals(Object, IEqualityComparer) Method

定义

返回一个值,该值指示基于指定的比较方法,当前 ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> 实例是否与指定的对象相等。Returns a value that indicates whether the current ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> instance is equal to a specified object based on a specified comparison method.

 virtual bool System.Collections.IStructuralEquatable.Equals(System::Object ^ other, System::Collections::IEqualityComparer ^ comparer) = System::Collections::IStructuralEquatable::Equals;
bool IStructuralEquatable.Equals (object other, System.Collections.IEqualityComparer comparer);
Function Equals (other As Object, comparer As IEqualityComparer) As Boolean Implements IStructuralEquatable.Equals

参数

other
Object Object Object

与该实例进行比较的对象。The object to compare with this instance.

comparer
IEqualityComparer IEqualityComparer IEqualityComparer

一个对象,该对象定义用于评估两个对象是否相等的方法。An object that defines the method to use to evaluate whether the two objects are equal.

返回

如果当前实例等于指定对象,则为 true;否则为 falsetrue if the current instance is equal to the specified objects; otherwise, false.

实现

注解

此成员是显式接口应用。This member is an explicit interface implementation. 仅可使用何时ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>实例转换为IStructuralEquatable接口。It can only be used when the ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> instance is cast to an IStructuralEquatable interface.

IEqualityComparer.Equals仅当调用实现other不是null,并可以成功地强制转换为ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>对象具有相同的类型的组件 (包括那些在嵌套的元组对象) 的相同的总数当前实例。The IEqualityComparer.Equals implementation is called only if other is not null, and if it can be successfully cast to a ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> object that has the same total number of components (including those in nested tuple objects) of the same types as the current instance. IStructuralEquatable.Equals(Object, IEqualityComparer)方法的第一次传入Item1的值ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>对象进行比较IEqualityComparer.Equals实现。The IStructuralEquatable.Equals(Object, IEqualityComparer) method first passes the Item1 values of the ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> objects to be compared to the IEqualityComparer.Equals implementation. 如果此方法调用返回true,方法是再次调用,传递Item2的两个值ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>对象。If this method call returns true, the method is called again and passed the Item2 values of the two ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> objects. 此过程将继续,直到该方法调用返回false时,它将比较一对特定的值或这两个Rest值传递给该方法。This continues until the method call returns false when it compares a specific pair of values, or the two Rest values are passed to the method.
