CloudBlobContainer.Create 方法 (BlobRequestOptions)
程序集： Microsoft.WindowsAzure.StorageClient（在 microsoft.windowsazure.storageclient.dll 中）
Containers are created immediately beneath the storage account. It's not possible to nest one container beneath another.
You can specify metadata on the container at the time that you created it. In this case, the call to Create writes the metadata to the new container, so it's not necessary to also call SetMetadata.
The Create method throws a StorageClientException if the specified container already exists. The error code returned by the service is ContainerAlreadyExists. If a container with the same name is still being deleted, the service returns error code ContainerBeingDeleted.
You can optionally create a default or root container for your storage account. The root container may be inferred from a URL requesting a blob resource. The root container makes it possible to reference a blob from the top level of the storage account hierarchy, without referencing the container name. To add the root container to your storage account, create a container named $root.
