Storage Client Library for Windows Phone (Version 7.0)

Initiates 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.

	content As String,
	encoding As Encoding,
	accessCondition As AccessCondition,
	options As BlobRequestOptions,
	operationContext As OperationContext,
	cancellationToken As CancellationToken
) As Task

Parameters

content

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

A string containing the text to upload.

encoding

Type: System.Text.EncodingSystem.Text::Encoding^System.Text.EncodingSystem.Text.Encoding

A Encoding object that indicates the text encoding to use. If null, UTF-8 will be used.

accessCondition

Type: Microsoft.WindowsAzure.Storage.AccessConditionMicrosoft.WindowsAzure.Storage::AccessCondition^Microsoft.WindowsAzure.Storage.AccessConditionMicrosoft.WindowsAzure.Storage.AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed.

options

Type: Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob::BlobRequestOptions^Microsoft.WindowsAzure.Storage.Blob.BlobRequestOptionsMicrosoft.WindowsAzure.Storage.Blob.BlobRequestOptions

A BlobRequestOptions object that specifies additional options for the request.

operationContext

Type: Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage::OperationContext^Microsoft.WindowsAzure.Storage.OperationContextMicrosoft.WindowsAzure.Storage.OperationContext

An OperationContext object that represents the context for the current operation.

cancellationToken

Type: System.Threading.CancellationTokenSystem.Threading::CancellationTokenSystem.Threading.CancellationTokenSystem.Threading.CancellationToken

A CancellationToken to observe while waiting for a task to complete.

Return Value

Type: System.Threading.Tasks.TaskSystem.Threading.Tasks::Task^System.Threading.Tasks.TaskSystem.Threading.Tasks.Task

A Task object that represents 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. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetryAbsorbConditionalErrorsOnRetryAbsorbConditionalErrorsOnRetryAbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario. To append data to an append blob that already exists, see AppendTextAsync.
