Type Parameters
- TSource
The type source.
Parameters
- source
Type: System.IObservable<TSource>
The source sequence to produce buffers over.
- timeSpan
Type: System.TimeSpan
The maximum time length of a buffer.
- count
Type: System.Int32
The maximum element count of a buffer.
- scheduler
Type: System.Reactive.Concurrency.IScheduler
The scheduler to run buffering timers on.
Return Value
Type: System.IObservable<IList<TSource>>
The observable sequence of buffers.
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 .
