Definition

Overloads

AppendFromStream(Stream, AccessCondition, BlobRequestOptions, OperationContext)

Appends a stream to an append blob. Recommended only for single-writer scenarios.

AppendFromStream(Stream, Int64, AccessCondition, BlobRequestOptions, OperationContext)

Appends a stream to an append blob. Recommended only for single-writer scenarios.

AppendFromStream(Stream, AccessCondition, BlobRequestOptions, OperationContext)

Appends a stream to an append blob. Recommended only for single-writer scenarios.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual void AppendFromStream (System.IO.Stream source, 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 AppendFromStream : System.IO.Stream * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unit
override this.AppendFromStream : System.IO.Stream * Microsoft.Azure.Storage.AccessCondition * Microsoft.Azure.Storage.Blob.BlobRequestOptions * Microsoft.Azure.Storage.OperationContext -> unit
Public Overridable Sub AppendFromStream (source As Stream, Optional accessCondition As AccessCondition = Nothing, Optional options As BlobRequestOptions = Nothing, Optional operationContext As OperationContext = Nothing)

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.

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.
