  • Reference

Definition

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

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.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginUploadText (string content, AsyncCallback callback, object state);
[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginUploadText : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginUploadText : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
Public Overridable Function BeginUploadText (content As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

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

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes
DoesServiceRequestAttribute

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).

Public Overridable Function BeginUploadText (content As String, encoding As Encoding, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

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

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

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes
DoesServiceRequestAttribute

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).
