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.

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. 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 BeginAppendText.
