TickCount

Gets a value that indicates the current tick count measured as milliseconds from an arbitrary reference time. The default implementation leverages . This is generally more efficient than GetStopwatchTime(), but provides less precision.

Declaration
long TickCount { get; }
Property Value
Type Description
System.Int64

Delay(Int32, CancellationToken)

Creates a cancellable task that completes after a specified time interval. This is equivalent to , and facilitates unit tests that use virtual time.

Declaration
Task Delay(int millisecondsDelay, CancellationToken cancellationToken)
Parameters
Type Name Description
System.Int32 millisecondsDelay

The number of milliseconds to wait before completing the returned task, or -1 to wait indefinitely.
CancellationToken cancellationToken

A cancellation token to observe while waiting for the task to complete.
Returns
Type Description
Task

A task that represents the time delay.

Delay(TimeSpan, CancellationToken)

Creates a cancellable task that completes after a specified time interval. This is equivalent to , and facilitates unit tests that use virtual time.

Declaration
Task Delay(TimeSpan delay, CancellationToken cancellationToken)
Parameters
Type Name Description
TimeSpan delay

The time span to wait before completing the returned task, or TimeSpan.FromMilliseconds(-1) to wait indefinitely.
CancellationToken cancellationToken

A cancellation token to observe while waiting for the task to complete.
Returns
Type Description
Task

A task that represents the time delay.
