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 if it exists.

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

'Usage
Dim instance As CloudBlob
Dim returnValue As Boolean

returnValue = instance.DeleteIfExists

'Declaration
Public Function DeleteIfExists As Boolean

Return Value

Type: System.Boolean

true if the blob was deleted; otherwise, false.

The following code example deletes a blob if it already exists.

static void UploadTextToBlob1(Uri blobEndpoint, string accountName, string accountKey)
{
    // Create a service client for credentialed access to the Blob service.
    CloudBlobClient blobClient = 
        new CloudBlobClient(blobEndpoint, new StorageCredentialsAccountAndKey(accountName, accountKey));

    // Return a reference to the blob.
    CloudBlob blob = blobClient.GetBlobReference("mycontainer/myblob.txt");

    // Delete the blob if it already exists
    blob.DeleteIfExists();
}

A blob that has snapshots cannot be deleted unless the snapshots are also deleted. If a blob has snapshots, use the DeleteSnapshotsOption property to specify how the snapshots should be handled when the blob is deleted.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
