Observable.ObserveOn(IObservable, IScheduler) method¶

Defined in

Type: Observable Namespace: System.Reactive.Linq Assembly: System.Reactive.dll

Applies to

netstandard2.0

Overloads¶

1. public static IObservable<TSource> ObserveOn<TSource>(this IObservable<TSource> source, IScheduler scheduler)
2. public static IObservable<TSource> ObserveOn<TSource>(this IObservable<TSource> source, SynchronizationContext context)

1. Overload¶

public static IObservable<TSource> ObserveOn<TSource>(this IObservable<TSource> source, IScheduler scheduler)

Summary: Wraps the source sequence in order to run its observer callbacks on the specified scheduler.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`source`	IObservable	Source sequence.
`scheduler`	[IScheduler](#	Scheduler to notify observers on.

Returns: IObservable -- The source sequence whose observations happen on the specified scheduler.

Remarks

This only invokes observer callbacks on a scheduler. In case the subscription and/or unsubscription actions have side-effects that require to be run on a scheduler, use SubscribeOn.

Exceptions

Type	Condition
System.ArgumentNullException	`source` or `scheduler` is null.

2. Overload¶

public static IObservable<TSource> ObserveOn<TSource>(this IObservable<TSource> source, SynchronizationContext context)

Summary: Wraps the source sequence in order to run its observer callbacks on the specified synchronization context.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`source`	IObservable	Source sequence.
`context`	SynchronizationContext	Synchronization context to notify observers on.

Returns: IObservable -- The source sequence whose observations happen on the specified synchronization context.

Remarks

This only invokes observer callbacks on a synchronization context. In case the subscription and/or unsubscription actions have side-effects that require to be run on a synchronization context, use SubscribeOn.

Exceptions

Type	Condition
System.ArgumentNullException	`source` or `context` is null.
