Uploads the contents of a byte array to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.

public virtual void UploadFromByteArray (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);

Public Overridable Sub UploadFromByteArray (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.

Implements

UploadFromByteArray(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext)

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. To append data to an append blob that already exists, see AppendFromByteArray(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext).
