示例1: LockAsync
/// <summary>
/// Creates a cloud lock, returning a class representing the lock.
/// </summary>
/// <param name="blob">The blob to lock.</param>
/// <returns>A <see cref="CloudLock"/> representing the lock, or null if no lock could be obtained.</returns>
public static async Task<CloudLock> LockAsync(CloudBlob blob)
{
// this creates the blob container
await blob.Container.CreateIfNotExistAsync();
// this creates the blob
await blob.CreateIfNotExistAsync();
// this leases the (possibly newly created) blob
var leaseId = await CloudBlobExtensions.TryAcquireLease(blob);
if (leaseId == null)
return null;
// this maintains the lease
var cts = new CancellationTokenSource();
return new CloudLock(blob, leaseId, cts);
