CloudAppendBlob.BeginAppendText Method

Definition

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.

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.
