CloudBlob.Metadata Property

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.]

Gets the blob's user-defined metadata.

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

用法
Dim instance As CloudBlob
Dim value As NameValueCollection

value = instance.Metadata

public NameValueCollection Metadata { get; }

Property Value

Type: System.Collections.Specialized.NameValueCollection

The metadata of the blob.

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 FetchAttributes method populates the system properties and user-defined metadata of a blob. Before reading the properties or metadata of a blob, you should always call this method or the BeginFetchAttributes method to retrieve the latest values for the properties and metadata of the blob from the service.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
