CloudBlobContainer.SetMetadata Method (BlobRequestOptions)

Updated: April 24, 2013

[This topic is part of the Microsoft Azure Storage Client Library 1.7, which has been deprecated. See Storage Client Library for the latest version.]

Sets the container's user-defined metadata, using a conditional request based on the BlobRequestOptions that you specify.

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

用法
Dim instance As CloudBlobContainer
Dim options As BlobRequestOptions

instance.SetMetadata(options)

public:
void SetMetadata (
	BlobRequestOptions^ options
)

Parameters

options

Type: Microsoft.WindowsAzure.StorageClient.BlobRequestOptions

An object that specifies any additional options for the request.

The following code example defines some metadata for a container and writes it to the container.

static void WriteContainerMetadata(Uri blobEndpoint, string accountName, string accountKey)
{
    //Create service client for credentialed access to the Blob service.
    CloudBlobClient blobClient = 
        new CloudBlobClient(blobEndpoint, 
                            new StorageCredentialsAccountAndKey(accountName, accountKey));

    //Return a container reference.
    CloudBlobContainer container = new CloudBlobContainer("mycontainer", blobClient);

    //Create the container if it does not exist.
    container.CreateIfNotExist();

    //Define some metadata for the container.
    container.Metadata["category"] = "images";
    container.Metadata["owner"] = "azureix";

    //Write the metadata to the service. Set a retry policy on the call.
    container.SetMetadata(
        new BlobRequestOptions() 
            { RetryPolicy = RetryPolicies.RetryExponential(10, RetryPolicies.DefaultClientBackoff) } 
        );}

The SetMetadata 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 blob reference only; you must call SetMetadata or BeginSetMetadata to write them to the service.

You can also set metadata on a container when the container is created, without calling SetMetadata.
