示例1: AutoRenewLease
public AutoRenewLease(CloudBlob blob)
{
this.blob = blob;
blob.Container.CreateIfNotExist();
try
{
blob.UploadByteArray(new byte[0], new BlobRequestOptions { AccessCondition = AccessCondition.IfNoneMatch("*") });
}
catch (StorageClientException e)
{
if (e.ErrorCode != StorageErrorCode.BlobAlreadyExists
&& e.StatusCode != HttpStatusCode.PreconditionFailed) // 412 from trying to modify a blob that's leased
{
throw;
}
}
leaseId = blob.TryAcquireLease();
if (HasLease)
{
renewalThread = new Thread(() =>
{
Thread.Sleep(TimeSpan.FromSeconds(40));
blob.RenewLease(leaseId);
});
renewalThread.Start();
}
