CloudAppendBlob.BeginAppendFromByteArray Method

Definition

Namespace:

Microsoft.Azure.Storage.Blob

Assembly:

Microsoft.Azure.Storage.Blob.dll

Package:

Microsoft.Azure.Storage.Blob v11.2.3

Overloads

BeginAppendFromByteArray(Byte[], Int32, Int32, AsyncCallback, Object)	Begins an asynchronous operation to append the contents of a byte array to an append blob. Recommended only for single-writer scenarios.
BeginAppendFromByteArray(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)	Begins an asynchronous operation to append the contents of a byte array to an append blob. Recommended only for single-writer scenarios.

BeginAppendFromByteArray(Byte[], Int32, Int32, AsyncCallback, Object)

Begins an asynchronous operation to append the contents of a byte array to an append blob. Recommended only for single-writer scenarios.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginAppendFromByteArray (byte[] buffer, int index, int count, AsyncCallback callback, object state);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginAppendFromByteArray : byte[] * int * int * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendFromByteArray : byte[] * int * int * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Overridable Function BeginAppendFromByteArray (buffer As Byte(), index As Integer, count As Integer, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

buffer

Byte[]

An array of bytes.

index

Int32

The zero-based byte offset in buffer at which to begin uploading bytes to the blob.

count

Int32

The number of bytes to be written to the blob.

callback

AsyncCallback

An AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state

Object

A user-defined object that will be passed to the callback delegate.

Returns

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes

DoesServiceRequestAttribute

Remarks

Use this method only in single-writer scenarios. Internally, this method uses the append-offset conditional header to avoid duplicate blocks, which may cause problems in multiple-writer scenarios.

Public Overridable Function BeginAppendFromByteArray (buffer As Byte(), index As Integer, count As Integer, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

buffer

Byte[]

An array of bytes.

index

Int32

The zero-based byte offset in buffer at which to begin uploading bytes to the blob.

count

Int32

The number of bytes to be written to the blob.

accessCondition

AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed.

options

BlobRequestOptions

A BlobRequestOptions object that specifies additional options for the request.

operationContext

OperationContext

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

callback

AsyncCallback

An AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state

Object

A user-defined object that will be passed to the callback delegate.

Returns

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes

DoesServiceRequestAttribute

Remarks

Use this method only in single-writer scenarios. Internally, this method uses the append-offset conditional header to avoid duplicate blocks, which may cause problems in multiple-writer scenarios. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario.
