CloudBlob.Delete Method ()

Updated: April 24, 2013

[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.]

Deletes the blob.

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

'Usage
Dim instance As CloudBlob

instance.Delete

'Declaration
Public Sub Delete

The following code example enumerates through the blobs in a container and deletes each blob.


static void DeleteBlobsAndSnapshots1(Uri blobEndpoint, string accountName, string accountKey)
{
    CloudBlobClient   blobClient = new CloudBlobClient(blobEndpoint, 
        new StorageCredentialsAccountAndKey(accountName, accountKey));

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

    // Since the Delete method exists only on CloudBlob objects (and not on IListBlobItem objects),
    // specify the Flat Blob Listing option, to ensure that ListBlobs() returns only CloudBlob objects.
    BlobRequestOptions options = new BlobRequestOptions();

    options.UseFlatBlobListing = true;

    // Delete each Blob in the container.
    foreach (CloudBlob blob in container.ListBlobs(options))
    {
        Console.WriteLine(blob.Uri);
        blob.Delete();
    }
}

A blob that has snapshots cannot be deleted unless the snapshots are also deleted. If a blob has snapshots, specify the options parameter, setting the DeleteSnapshotsOption property to specify how the snapshots should be handled when the blob is deleted. If you attempt to delete a blob without also deleting its snapshots, this method will fail with HTTPStatusCode.Conflict.

The Delete method will fail if the blob does not exist. To delete the blob only if it exists, use the DeleteIfExists method.
