Type: System.Collections.Specialized.NameValueCollection

The metadata of the blob.

Example

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();
}

Remarks

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.

Thread Safety

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