Observable.Replay<TSource, TResult> Method (IObservable<TSource>, Func<IObservable<TSource>, IObservable<TResult>>, Int32, TimeSpan, IScheduler)
Returns an observable sequence that is the result of invoking the selector on a connectable observable sequence that shares a single subscription to the underlying sequence replaying bufferSize notifications within window.

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

Type Parameters
- TSource
The type of source.
- TResult
The type of result.
Parameters
- source
Type: System.IObservable<TSource>
The source sequence whose elements will be multicasting through a single shared subscription.
- selector
Type: System.Func<IObservable<TSource>, IObservable<TResult>>
The selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence.
- bufferSize
Type: System.Int32
The maximum element count of the replay buffer.
- window
Type: System.TimeSpan
The maximum time length of the replay buffer.
- scheduler
Type: System.Reactive.Concurrency.IScheduler
The scheduler where connected observers within the selector function will be invoked on.
Return Value
Type: System.IObservable<TResult>
An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
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 .
