Type Parameters

  • TSource
    The type of source.


  • timeShift
    Type: System.TimeSpan
    The interval between creation of consecutive windows.

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 .
