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

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);
abstract member System.Collections.IStructuralEquatable.Equals : obj * System.Collections.IEqualityComparer -> bool
override this.System.Collections.IStructuralEquatable.Equals : obj * System.Collections.IEqualityComparer -> bool
Function Equals (other As Object, comparer As IEqualityComparer) As Boolean Implements IStructuralEquatable.Equals

参数

other
Object

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

comparer
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

Boolean

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. 它只能在 ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> 实例被强制转换为接口时使用 IStructuralEquatableIt can only be used when the ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> instance is cast to an IStructuralEquatable interface.

IEqualityComparer.Equals仅当不为时,才会调用实现 other null ,并且如果它可以成功地强制转换为 ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> 具有相同的组件总数 (包括嵌套元组对象) 与当前实例相同的类型的对象。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)方法首先传递 Item1 ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest> 要与实现进行比较的对象的值 IEqualityComparer.EqualsThe 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 ,将再次调用方法并传递 Item2 两个对象的值 ValueTuple<T1,T2,T3,T4,T5,T6,T7,TRest>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,直到方法调用 false 在比较特定对值时返回,或将两个 Rest 值传递给方法。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.
