Package:
Microsoft.Azure.Storage.Blob v11.2.3

Overloads

UploadFromStream(Stream, AccessCondition, BlobRequestOptions, OperationContext)

Uploads a stream to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.
UploadFromStream(Stream, Int64, AccessCondition, BlobRequestOptions, OperationContext)

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

Parameters

source
Stream

A Stream object providing the blob content.

accessCondition
AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.

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

UploadFromStream(Stream, 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 AppendFromStream(Stream, AccessCondition, BlobRequestOptions, OperationContext).
