<DoesServiceRequestAttribute>
Public Function GetPageRangesDiffAsync (
	previousSnapshotTime As DateTimeOffset,
	cancellationToken As CancellationToken
) As Task(Of IEnumerable(Of PageDiffRange))

Parameters

previousSnapshotTime

Type: System.DateTimeOffsetSystem::DateTimeOffsetSystem.DateTimeOffsetSystem.DateTimeOffset

A DateTimeOffset representing the snapshot timestamp to use as the starting point for the diff. If this CloudPageBlob represents a snapshot, the previousSnapshotTime parameter must be prior to the current snapshot timestamp.

cancellationToken

Type: System.Threading.CancellationTokenSystem.Threading::CancellationTokenSystem.Threading.CancellationTokenSystem.Threading.CancellationToken

A CancellationToken to observe while waiting for a task to complete.

Return Value

Type: System.Threading.Tasks.Task<IEnumerable<PageDiffRange>>System.Threading.Tasks::Task<IEnumerable<PageDiffRange^>^>^System.Threading.Tasks.Task<IEnumerable<PageDiffRange>>System.Threading.Tasks.Task(Of IEnumerable(Of PageDiffRange))

A Task<TResult><TResult><'TResult>(Of TResult) object that is an enumerable collection of type PageRange that represents the asynchronous operation.
