BeginUploadFromFile(String, AsyncCallback, Object)

开始异步操作，将文件上传到文件服务。如果服务上已存在该文件，则会覆盖该文件。

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

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

Public Overridable Function BeginUploadFromFile (path As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

参数

path: String

提供内容的文件。

callback: AsyncCallback

异步操作完成时接收通知的回调委托。

state: Object

将传递给回调委托的用户定义对象。
