BeginDownloadToFile(String, FileMode, AsyncCallback, Object)

开始异步操作，将 Blob 的内容下载到文件。

public Microsoft.Azure.Storage.ICancellableAsyncResult BeginDownloadToFile (string path, System.IO.FileMode mode, AsyncCallback callback, object state);

abstract member BeginDownloadToFile : string * System.IO.FileMode * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Function BeginDownloadToFile (path As String, mode As FileMode, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

参数

path: String

包含目标文件路径的字符串。

mode: FileMode

一个 FileMode 枚举值，用于确定如何打开或创建文件。

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
