Type Parameters
- TSource
The type of source.
Parameters
- source
Type: System.Reactive.Linq.IQbservable<TSource>
The source sequence to produce windows over.
- timeSpan
Type: System.TimeSpan
The maximum time length of a window.
- count
Type: System.Int32
The maximum element count of a window.
- scheduler
Type: System.Reactive.Concurrency.IScheduler

Return Value
Type: System.Reactive.Linq.IQbservable<IObservable<TSource>>
A queryable observable sequence of windows.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IQbservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
