1. Overload¶

public static IObservableAsync<long> Timer(TimeSpan dueTime)

View source

Summary: Creates an observable sequence that produces a single value (0) after the specified delay, then completes.

Parameters

Name	Type	Description
`dueTime`	TimeSpan	The time span after which to produce the value. Must be non-negative.

Returns: IObservableAsync -- An observable sequence that produces a single value after the specified delay and then completes.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	Thrown if `dueTime` is negative.

2. Overload¶

public static IObservableAsync<long> Timer(TimeSpan dueTime, TimeProvider? timeProvider)

View source

Summary: Creates an observable sequence that produces a single value (0) after the specified delay, then completes.

Parameters

Name	Type	Description
`dueTime`	TimeSpan	The time span after which to produce the value. Must be non-negative.
`timeProvider`	TimeProvider?	An optional time provider for controlling timing. If null, System is used.

Returns: IObservableAsync -- An observable sequence that produces a single value after the specified delay and then completes.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	Thrown if `dueTime` is negative.

3. Overload¶

public static IObservableAsync<long> Timer(TimeSpan dueTime, TimeSpan period)

View source

Summary: Creates an observable sequence that produces a single value (0) after the specified delay, then continues to produce sequential values at each specified period.

Parameters

Name	Type	Description
`dueTime`	TimeSpan	The initial delay before the first value is produced. Must be non-negative.
`period`	TimeSpan	The interval between subsequent values after the initial delay. Must be positive.

Returns: IObservableAsync -- An observable sequence that produces values starting after the initial delay and continuing at the specified period.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	Thrown if `dueTime` is negative or `period` is non-positive.

4. Overload¶

public static IObservableAsync<long> Timer(TimeSpan dueTime, TimeSpan period, TimeProvider? timeProvider)

View source

Summary: Creates an observable sequence that produces a single value (0) after the specified delay, then continues to produce sequential values at each specified period.

Parameters

Name	Type	Description
`dueTime`	TimeSpan	The initial delay before the first value is produced. Must be non-negative.
`period`	TimeSpan	The interval between subsequent values after the initial delay. Must be positive.
`timeProvider`	TimeProvider?	An optional time provider for controlling timing. If null, System is used.

Returns: IObservableAsync -- An observable sequence that produces values starting after the initial delay and continuing at the specified period.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	Thrown if `dueTime` is negative or `period` is non-positive.
