Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)
Usage

Dim instance As CloudBlobContainer Dim options As BlobRequestOptions Dim callback As AsyncCallback Dim state As Object Dim returnValue As IAsyncResult returnValue = instance.BeginSetMetadata(options, callback, state) |
Syntax
| Visual Basic |

Public Function BeginSetMetadata ( _ options As BlobRequestOptions, _ callback As AsyncCallback, _ state As Object _ ) As IAsyncResult |
| C# |

Parameters
- options
Type: Microsoft.WindowsAzure.StorageClient.BlobRequestOptions
An object that specifies any additional options for the request.
- callback
Type: System.AsyncCallback
The callback delegate that will receive notification when the asynchronous operation completes.
- state
Type: System.Object
A user-defined object that will be passed to the callback delegate.
Return Value
Type: System.IAsyncResult
An IAsyncResult that references the asynchronous operation.
Remarks
The BeginSetMetadata method writes the metadata values that are specified by the container's Metadata property to the service. Note that setting the Metadata property sets metadata values on the container reference only; you must call BeginSetMetadata or SetMetadata to write them to the service.
