如何从PowerShell自动化获得输出？

Question

我正在尝试将输出和PowerShell实例的输出发布到文本框中。我的代码：

Private Sub ViewServiceLogToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles ViewServiceLogToolStripMenuItem.Click
    Using ps As PowerShell = PowerShell.Create()
        Dim logFilePathName As String = "some path to log file"
        ps.AddScript(String.Format("get-content {0} -wait", logFilePathName))
        Dim outputCollection As PSDataCollection(Of PSObject) = New PSDataCollection(Of PSObject)
        AddHandler outputCollection.DataAdded, AddressOf LogFileOutput
        Dim result As IAsyncResult = ps.BeginInvoke(Of PSObject, PSObject)(Nothing, outputCollection)
    End Using
End Sub

Sub LogFileOutput(send As Object, data As DataAddedEventArgs)
    LogTextBox.Text += data.ToString
End Sub

我不确定这是否正在运行。永远不会引发在LogFileOutput处理程序子句中放置断点。感谢。
