Observable.SequenceEqual<TSource> Method (IObservable<TSource>, IObservable<TSource>, IEqualityComparer<TSource>)

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

Namespace:  System.Reactive.Linq
Assembly:  System.Reactive (in System.Reactive.dll)

[ExtensionAttribute]
public:
generic<typename TSource>

    IObservable<TSource>^ first, 
    IObservable<TSource>^ second, 
    IEqualityComparer<TSource>^ comparer

JScript does not support generic types and methods.

Type Parameters

• TSource
  The type of source.

Parameters

• first
  Type: System.IObservable<TSource>
  First observable sequence to compare.

• second
  Type: System.IObservable<TSource>
  Second observable sequence to compare.

• comparer
  Type: System.Collections.Generic.IEqualityComparer<TSource>
  A comparer used to compare elements of both sequences.

Return Value

Type: System.IObservable<Boolean>
True if two sequences are equal by comparing the elements pairwise using a specified equality comparer; otherwise, false.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
