Storage Client Library NET API

[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.]

Retrieves the container's attributes, including its system properties and user-defined metadata.

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

Usage

Visual Basic
Dim instance As CloudBlobContainer

instance.FetchAttributes

Syntax

Visual Basic
Public Sub FetchAttributes
C#
public void FetchAttributes ()
C++
public:
void FetchAttributes ()
J#
JScript

Example

The following code example fetches the container's attributes and writes out its properties and metadata.

C# Copy Code
static void ListContainerPropertiesAndMetadata(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));

    //Get a reference to a container.
    CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");

    //Populate the container's attributes.
    container.FetchAttributes();

    //List some container properties.
    Console.WriteLine("Container: " + container.Name);
    Console.WriteLine();

    Console.WriteLine("Container properties:");
    Console.WriteLine("\tLastModifiedUTC: " + container.Attributes.Properties.LastModifiedUtc);
    Console.WriteLine("\tETag: " + container.Attributes.Properties.ETag);
    Console.WriteLine();

    //Enumerate the container's metadata.
    foreach (var metadataKey in container.Metadata.Keys)
    {
        Console.WriteLine("Metadata name: " + metadataKey.ToString());
        Console.WriteLine("Metadata value: " + container.Metadata.Get(metadataKey.ToString()));
    }
}

Remarks

The FetchAttributes method begins an operation to populate the container's system properties and user-defined metadata. Before reading a container's properties or metadata, you should always call this method or the BeginFetchAttributes method to retrieve the latest values for the container's properties and metadata from the service.
