Type Parameters
- TLeft
The type of left.
- TRight
The type of right.
- TLeftDuration
The type of left duration.
- TRightDuration
The type of right duration.
- TResult
The type of result.
Parameters
- left
Type: System.IObservable<TLeft>
The left observable sequence to join elements for.
- right
Type: System.IObservable<TRight>
The right observable sequence to join elements for.
- leftDurationSelector
Type: System.Func<TLeft, IObservable<TLeftDuration>>
A function to select the duration of each element of the left observable sequence, used to determine overlap.
- rightDurationSelector
Type: System.Func<TRight, IObservable<TRightDuration>>
A function to select the duration of each element of the right observable sequence, used to determine overlap.
- resultSelector
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. For more information, see or .
