Observable.Switch(IObservable>) method¶

Overloads¶

• 1. public static IObservable<TSource> Switch<TSource>(this IObservable<IObservable<TSource>> sources)
• 2. public static IObservable<TSource> Switch<TSource>(this IObservable<Task<TSource>> sources)

1. Overload¶

public static IObservable<TSource> Switch<TSource>(this IObservable<IObservable<TSource>> sources)

Summary: Transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence. Each time a new inner observable sequence is received, unsubscribe from the previous inner observable sequence.

Type parameters

Parameters

Returns: IObservable -- The observable sequence that at any point in time produces the elements of the most recent inner observable sequence that has been received.

Exceptions

2. Overload¶

public static IObservable<TSource> Switch<TSource>(this IObservable<Task<TSource>> sources)

Summary: Transforms an observable sequence of tasks into an observable sequence producing values only from the most recent observable sequence. Each time a new task is received, the previous task's result is ignored.

Type parameters

Parameters

Returns: IObservable -- The observable sequence that at any point in time produces the result of the most recent task that has been received.

Remarks

If the tasks support cancellation, consider manual conversion of the tasks using FromAsync, followed by a switch operation using Switch.
