CloudAppendBlob.BeginUploadText Method (String, AsyncCallback, Object) (Microsoft.WindowsAzure.Storage.Blob)
From Microsoft Windows Azure Storage Blob
Begins an asynchronous operation to upload a string of text to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.
Namespace:
Microsoft.WindowsAzure.Storage.Blob
Assembly:
Microsoft.WindowsAzure.Storage (in Microsoft.WindowsAzure.Storage.dll)
Syntax

string content,
AsyncCallback callback,
object state

) As ICancellableAsyncResult
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.ICancellableAsyncResultAn 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.
