如何访问WebClient.DownloadDataAsync获取的数据？

Question

（这是的后续问题。）

我想异步读取无穷无尽的音频流，以便对获取的数据进行 JIT 分析。使用 WebClient 对象的 DownloadDataAsync 方法，我可以轻松启动下载，请参阅以下 Win 窗体项目：

Imports System.Net      'For WebClient

Public Class Form1
    Private WithEvents c As New WebClient()

    Protected Overrides Sub Finalize()
        c.Dispose()
        MyBase.Finalize()
    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim u As New Uri("http://flower.serverhostingcenter.com:8433/;")
        c.DownloadDataAsync(u)
    End Sub

    Private Sub c_DownloadProgressChanged(sender As Object, e As DownloadProgressChangedEventArgs) Handles c.DownloadProgressChanged
        Debug.Print(e.BytesReceived.ToString & " B received.")
    End Sub
End Class

并且流似乎在流动，根据 DownloadProgressChanged 事件的输出到即时 window:

2920 B received.
48180 B received.
56940 B received.
61320 B received.
87600 B received.
94900 B received.
160436 B received.
162060 B received.
227596 B received.
...

但是，我找不到一种方法来也读取获得的数据。由于这是一个无穷无尽的流，DownloadDataCompleted 将永远不会触发（除了使用的事件之外，任何其他事件也不会触发）。

如何访问获取的数据？

Answer 1

将 OpenReadAsync 与 OpenReadCompleted 事件结合使用。

Private Sub c_OpenReadCompleted(sender As Object, e As OpenReadCompletedEventArgs) Handles c.OpenReadCompleted
   Dim stream = e.Result
End Sub
