Observable.SequenceEqual(IObservable, IObservable) method¶

Defined in

Type: Observable Namespace: System.Reactive.Linq Assembly: System.Reactive.dll

Applies to

netstandard2.0

Overloads¶

1. public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IObservable<TSource> second)
2. public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IObservable<TSource> second, IEqualityComparer<TSource> comparer)
3. public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IEnumerable<TSource> second)
4. public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IEnumerable<TSource> second, IEqualityComparer<TSource> comparer)

1. Overload¶

public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IObservable<TSource> second)

Summary: Determines whether two sequences are equal by comparing the elements pairwise.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`first`	IObservable	First observable sequence to compare.
`second`	IObservable	Second observable sequence to compare.

Returns: IObservable -- An observable sequence that contains a single element which indicates whether both sequences are of equal length and their corresponding elements are equal according to the default equality comparer for their type.

Remarks

The return type of this operator differs from the corresponding operator on IEnumerable in order to retain asynchronous behavior.

Exceptions

Type	Condition
System.ArgumentNullException	`first` or `second` is null.

2. Overload¶

public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IObservable<TSource> second, IEqualityComparer<TSource> comparer)

Summary: Determines whether two sequences are equal by comparing the elements pairwise using a specified equality comparer.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`first`	IObservable	First observable sequence to compare.
`second`	IObservable	Second observable sequence to compare.
`comparer`	IEqualityComparer	Comparer used to compare elements of both sequences.

Returns: IObservable -- An observable sequence that contains a single element which indicates whether both sequences are of equal length and their corresponding elements are equal according to the specified equality comparer.

Remarks

The return type of this operator differs from the corresponding operator on IEnumerable in order to retain asynchronous behavior.

Exceptions

Type	Condition
System.ArgumentNullException	`first` or `second` or `comparer` is null.

3. Overload¶

public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IEnumerable<TSource> second)

Summary: Determines whether an observable and enumerable sequence are equal by comparing the elements pairwise.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`first`	IObservable	First observable sequence to compare.
`second`	IEnumerable	Second observable sequence to compare.

Returns: IObservable -- An observable sequence that contains a single element which indicates whether both sequences are of equal length and their corresponding elements are equal according to the default equality comparer for their type.

Remarks

The return type of this operator differs from the corresponding operator on IEnumerable in order to retain asynchronous behavior.

Exceptions

Type	Condition
System.ArgumentNullException	`first` or `second` is null.

4. Overload¶

public static IObservable<bool> SequenceEqual<TSource>(this IObservable<TSource> first, IEnumerable<TSource> second, IEqualityComparer<TSource> comparer)

Summary: Determines whether an observable and enumerable sequence are equal by comparing the elements pairwise using a specified equality comparer.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`first`	IObservable	First observable sequence to compare.
`second`	IEnumerable	Second observable sequence to compare.
`comparer`	IEqualityComparer	Comparer used to compare elements of both sequences.

Returns: IObservable -- An observable sequence that contains a single element which indicates whether both sequences are of equal length and their corresponding elements are equal according to the specified equality comparer.

Remarks

The return type of this operator differs from the corresponding operator on IEnumerable in order to retain asynchronous behavior.

Exceptions

Type	Condition
System.ArgumentNullException	`first` or `second` or `comparer` is null.
