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.

offset

Type: System.Nullable<Int64>System::Nullable<Int64>System.Nullable<Int64>System.Nullable(Of Int64)

The starting offset of the data range, in bytes. Must be a multiple of 512.

length

Type: System.Nullable<Int64>System::Nullable<Int64>System.Nullable<Int64>System.Nullable(Of Int64)

The length of the data range, in bytes. Must be a multiple of 512.

accessCondition

Type: Microsoft.WindowsAzure.Storage.AccessConditionMicrosoft.WindowsAzure.Storage::AccessCondition^Microsoft.WindowsAzure.Storage.AccessConditionMicrosoft.WindowsAzure.Storage.AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.

options

Type: Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob::BlobRequestOptions^Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob.BlobRequestOptions

A BlobRequestOptions object that specifies additional options for the request.

operationContext

Type: Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage::OperationContext^Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage.OperationContext

An OperationContext object that represents the context for the current operation.

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.
