我最近能够成功使用一个名为RokuDotNet的库。它是用 C# 编写的,但您可以将其作为项目加载到您的解决方案中并从 VB.NET 中引用它。
这大致是我使用它的方式:
Imports RokuDotNet.Client
Public Class Form1
Private _discoveryClient As RokuDeviceDiscoveryClient
Public Sub New()
_discoveryClient = New RokuDeviceDiscoveryClient
AddHandler _discoveryClient.DeviceDiscovered, AddressOf DiscoveryHandler
End Sub
Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles MyBase.Shown
_discoveryClient.DiscoverDevicesAsync()
End Sub
Private Async Sub DiscoveryHandler(sender As Object, e As DeviceDiscoveredEventArgs)
If InvokeRequired Then
BeginInvoke(New Action(Sub() DiscoveryHandler(sender, e)))
Return
End If
' Get the display name for the device (if the user entered one when setting it up)
Dim deviceInfo = Await e.Device.Query.GetDeviceInfoAsync
Dim name = deviceInfo.UserDeviceName
If String.IsNullOrEmpty(name) Then
name = deviceInfo.ModelName
End If
AddDevice(e.Device, name)
End Sub
Private Sub AddDevice(device As RokuDevice, name As String)
' Your code here
End Sub
End Class
您可能希望在该异步函数中的 await 周围添加一个 try/catch,以便在出现网络问题时显示错误。
