Parameters

content

Type: System.StringSystem::String^System.StringSystem.String

A string containing the text to upload.

callback

Type: System.AsyncCallbackSystem::AsyncCallback^System.AsyncCallbackSystem.AsyncCallback

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

state

Type: System.ObjectSystem::Object^System.ObjectSystem.Object

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

Return Value

Type: Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage::ICancellableAsyncResult^Microsoft.WindowsAzure.Storage.ICancellableAsyncResultMicrosoft.WindowsAzure.Storage.ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

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. To append data to an append blob that already exists, see BeginAppendText.
