Overloads
| BeginUploadText(String, AsyncCallback, Object) |
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. |
| BeginUploadText(String, Encoding, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object) |
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. |
BeginUploadText(String, AsyncCallback, Object)
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.

abstract member BeginUploadText : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginUploadText : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResultPublic Overridable Function BeginUploadText (content As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResultParameters
- content
- String
A string containing the text to upload.
- callback
- AsyncCallback
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 ICancellableAsyncResult that references the asynchronous 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. To append data to an append blob that already exists, see BeginAppendText(String, AsyncCallback, Object).

- content
- String
A string containing the text to upload.
- encoding
- Encoding
A Encoding object that indicates the text encoding to use. If null, UTF-8 will be used.
- accessCondition
- AccessCondition
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

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. To append data to an append blob that already exists, see BeginAppendText(String, Encoding, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object).
