Observable.GroupJoin<TLeft, TRight, TLeftDuration, TRightDuration, TResult> Method

Correlates the elements of two sequences based on overlapping durations, and groups the results.

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

public static IObservable<TResult> GroupJoin<TLeft, TRight, TLeftDuration, TRightDuration, TResult>(
	this IObservable<TLeft> left,
	IObservable<TRight> right,
	Func<TLeft, IObservable<TLeftDuration>> leftDurationSelector,
	Func<TRight, IObservable<TRightDuration>> rightDurationSelector,
	Func<TLeft, IObservable<TRight>, TResult> resultSelector

Type Parameters


The type of left.


The type of right.


The type of left duration.


The type of right duration.


The type of result.


Type: System.IObservable<TLeft>
The left observable sequence to join elements for.
Type: System.IObservable<TRight>
The right observable sequence to join elements for.
Type: System.Func<TLeft, IObservable<TLeftDuration>>
A function to select the duration of each element of the left observable sequence, used to determine overlap.
Type: System.Func<TRight, IObservable<TRightDuration>>
A function to select the duration of each element of the right observable sequence, used to determine overlap.
Type: System.Func<TLeft, IObservable<TRight>, TResult>
A function invoked to compute a result element for any element of the left sequence with overlapping elements from the right observable sequence.

Return Value

Type: System.IObservable<TResult>
An observable sequence that contains result elements computed from source elements that have an overlapping duration.

Usage Note

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