参数

target: Stream

一个 Stream 表示目标流的对象。

offset: Nullable<Int64>

开始下载 Blob 的偏移量（以字节为单位）。

length: Nullable<Int64>

要从 Blob 下载的数据的长度（以字节为单位）。

callback: AsyncCallback

在 AsyncCallback 异步操作完成时接收通知的委托。

state: Object

将传递给回调委托的用户定义对象。

ICancellableAsyncResult

引用 ICancellableAsyncResult 异步操作的。

属性: DoesServiceRequestAttribute
