CloudBlob.SetMetadata Method ()

Updated: April 24, 2013

[This topic is part of the Windows Azure Storage Client Library 1.7, which has been deprecated. The current recommended version is Storage Client Library 3.0.]

Updates the blob's metadata.

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

'Utilisation

public void SetMetadata ()

The following code example writes metadata to a blob.

static void WriteBlobMetadata(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 blob reference.
    CloudBlob blob = new CloudBlob("mycontainer/myblob.txt", blobClient);

    // Write some text to the blob.
    blob.UploadText("this is a text blob");

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

    // Write the metadata to the service.
    blob.SetMetadata();
}

The SetMetadata method writes the metadata values that are specified by the blob's Metadata property to the service. Note that setting the Metadata property sets metadata values on the blob reference only; you must call BeginSetMetadata or SetMetadata to write them to the service.
