<DoesServiceRequestAttribute> Public Function BeginGetPageRangesDiff ( previousSnapshotTime As DateTimeOffset, offset As Nullable(Of Long), length As Nullable(Of Long), accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, callback As AsyncCallback, state As Object ) As ICancellableAsyncResult
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 over which to list page ranges, 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 over which to list page ranges, 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.
- callback
-
Type:
System.AsyncCallbackSystem::AsyncCallback^System.AsyncCallbackSystem.AsyncCallback
An AsyncCallback delegate that will receive notification when the asynchronous operation completes.
- state
-
Type:
System.ObjectSystem::Object^System.ObjectSystem.Object
A user-defined object that will be passed to the callback delegate.
Return Value
Type: Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage::ICancellableAsyncResult^Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage.ICancellableAsyncResultAn ICancellableAsyncResult that references the asynchronous operation.
