public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginDownloadText (AsyncCallback callback, object state);

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

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

参数

callback: AsyncCallback

在 AsyncCallback 异步操作完成时接收通知的委托。

state: Object
