Namespace:
Microsoft.Azure.Storage.Blob
Assembly:
Microsoft.Azure.Storage.Blob.dll
Package:
Microsoft.Azure.Storage.Blob v11.2.3

Overloads

BeginAppendText(String, AsyncCallback, Object)

Begins an asynchronous operation to append a string of text to an append blob. This API should be used strictly in a single writer scenario because the API internally uses the append-offset conditional header to avoid duplicate blocks which does not work in a multiple writer scenario.
BeginAppendText(String, Encoding, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)

Begins an asynchronous operation to append a string of text to an append blob. This API should be used strictly in a single writer scenario because the API internally uses the append-offset conditional header to avoid duplicate blocks which does not work in a multiple writer scenario.

Public Overridable Function BeginAppendText (content As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

content
String

A string containing the text to upload.

callback

An AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state
Object

A user-defined object that will be passed to the callback delegate.

Returns

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.

operationContext
OperationContext

An OperationContext object that represents the context for the current operation.

callback
AsyncCallback

An AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state
Object

Remarks

If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario.
