Observable.DelaySubscription(IObservable, TimeSpan) method¶

Defined in

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

Applies to

netstandard2.0

Overloads¶

1. public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, TimeSpan dueTime)
2. public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, TimeSpan dueTime, IScheduler scheduler)
3. public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, DateTimeOffset dueTime)
4. public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, DateTimeOffset dueTime, IScheduler scheduler)

1. Overload¶

public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, TimeSpan dueTime)

Summary: Time shifts the observable sequence by delaying the subscription with the specified relative time duration.

Type parameters

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

Parameters

Name	Type	Description
`source`	IObservable	Source sequence to delay subscription for.
`dueTime`	TimeSpan	Relative time shift of the subscription.

Returns: IObservable -- Time-shifted sequence.

Remarks

This operator is more efficient than Delay but postpones all side-effects of subscription and affects error propagation timing.

The side-effects of subscribing to the source sequence will be run on the default scheduler. Observer callbacks will not be affected.

Exceptions

Type	Condition
System.ArgumentNullException	`source` is null.
System.ArgumentOutOfRangeException	`dueTime` is less than TimeSpan.Zero.

2. Overload¶

public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, TimeSpan dueTime, IScheduler scheduler)

Summary: Time shifts the observable sequence by delaying the subscription with the specified relative time duration, using the specified scheduler to run timers.

Type parameters

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

Parameters

Name	Type	Description
`source`	IObservable	Source sequence to delay subscription for.
`dueTime`	TimeSpan	Relative time shift of the subscription.
`scheduler`	[IScheduler](#	Scheduler to run the subscription delay timer on.

Returns: IObservable -- Time-shifted sequence.

Remarks

This operator is more efficient than Delay but postpones all side-effects of subscription and affects error propagation timing.

The side-effects of subscribing to the source sequence will be run on the specified scheduler. Observer callbacks will not be affected.

Exceptions

Type	Condition
System.ArgumentNullException	`source` or `scheduler` is null.
System.ArgumentOutOfRangeException	`dueTime` is less than TimeSpan.Zero.

3. Overload¶

public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, DateTimeOffset dueTime)

Summary: Time shifts the observable sequence by delaying the subscription to the specified absolute time.

Type parameters

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

Parameters

Name	Type	Description
`source`	IObservable	Source sequence to delay subscription for.
`dueTime`	DateTimeOffset	Absolute time to perform the subscription at.

Returns: IObservable -- Time-shifted sequence.

Remarks

This operator is more efficient than Delay but postpones all side-effects of subscription and affects error propagation timing.

The side-effects of subscribing to the source sequence will be run on the default scheduler. Observer callbacks will not be affected.

Exceptions

Type	Condition
System.ArgumentNullException	`source` is null.

4. Overload¶

public static IObservable<TSource> DelaySubscription<TSource>(this IObservable<TSource> source, DateTimeOffset dueTime, IScheduler scheduler)

Summary: Time shifts the observable sequence by delaying the subscription to the specified absolute time, using the specified scheduler to run timers.

Type parameters

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

Parameters

Name	Type	Description
`source`	IObservable	Source sequence to delay subscription for.
`dueTime`	DateTimeOffset	Absolute time to perform the subscription at.
`scheduler`	[IScheduler](#	Scheduler to run the subscription delay timer on.

Returns: IObservable -- Time-shifted sequence.

Remarks

This operator is more efficient than Delay but postpones all side-effects of subscription and affects error propagation timing.

The side-effects of subscribing to the source sequence will be run on the specified scheduler. Observer callbacks will not be affected.

Exceptions

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