Syntax
| Visual Basic |
|---|
Public Function GetBlockBlobReference ( _ blobAddress As String, _ snapshotTime As Nullable(Of DateTime) _ ) As CloudBlockBlob |
| C# |
|---|
public CloudBlockBlob GetBlockBlobReference ( string blobAddress, Nullable<DateTime> snapshotTime ) |
| C++ |
|---|
public: CloudBlockBlob^ GetBlockBlobReference ( String^ blobAddress, Nullable<DateTime> snapshotTime ) |
| J# |

| JScript |

Parameters
- blobAddress
Type: System.String
The absolute URI to the blob, or a relative URI beginning with the container name.
- snapshotTime
Type: System.Nullable
The snapshot timestamp, if the blob is a snapshot.
Return Value
Type: Microsoft.WindowsAzure.StorageClient.CloudBlockBlobA reference to a block blob.Remarks
The GetBlockBlobReference method returns a reference to the named block blob, but it does not indicate whether the blob exists, as it does not make a round-trip to the service. If you need to ascertain the blob's existence, call a method such as FetchAttributes, and handle the resulting StorageClientException in the event the blob does not exist. The FetchAttributes method executes a HEAD request to populate the blob's properties and metadata and as such is a lightweight option for determining whether the blob exists.
