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>]

override this.AppendFromByteArray : byte[] * int * int * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unitPublic 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
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.
