Definition

Namespace:

Microsoft.Azure.Storage.Blob

Assembly:

Microsoft.Azure.Storage.Blob.dll

Package:

Microsoft.Azure.Storage.Blob v11.2.3

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

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual void AppendFromByteArray (byte[] buffer, int index, int count, Microsoft.Azure.Storage.AccessCondition accessCondition = default, Microsoft.Azure.Storage.Blob.BlobRequestOptions options = default, Microsoft.Azure.Storage.OperationContext operationContext = default);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member AppendFromByteArray : byte[] * int * int * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unit
override this.AppendFromByteArray : byte[] * int * int * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unit

Public Overridable Sub AppendFromByteArray (buffer As Byte(), index As Integer, count As Integer, Optional accessCondition As AccessCondition = Nothing, Optional options As BlobRequestOptions = Nothing, Optional operationContext As OperationContext = Nothing)

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. If null, default options are applied to the request.

operationContext

OperationContext

An OperationContext object that represents the context for the current 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.
