Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

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.

[Microsoft.Azure.Storage.DoesServiceRequest]
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);

abstract member UploadFromByteArray : byte[] * int * int * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unit

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).
