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.
