[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginDownloadBlockList (AsyncCallback callback, object state);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginDownloadBlockList : AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginDownloadBlockList : AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Overridable Function BeginDownloadBlockList (callback As AsyncCallback, state As Object) As ICancellableAsyncResult

参数

callback: AsyncCallback
