示例1: DoOnceAsync
public static async Task DoOnceAsync(CloudBlob blob, Func<Task> action, TimeSpan pollingFrequency)
{
// blob.Exists has the side effect of calling blob.FetchAttributes, which populates the metadata collection
while (!blob.Exists() || blob.Metadata["progress"] != "done")
{
using (var @lock = await CloudLock.LockAsync(blob))
{
if (@lock != null)
{
await action();
blob.Metadata["progress"] = "done";
await blob.SetMetadataAsync(@lock._leaseId);
}
else
{
await TaskEx.Delay(pollingFrequency);
}
}
}
}示例2: DoOnce
