Parameters

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.
