Runspace02-codevoorbeeld (VB.NET)

Hier is de VB.NET broncode voor het Runspace02-voorbeeld. In dit voorbeeld wordt de klasse System.Management.Automation.Runspaceinvoke gebruikt om de Get-Process cmdlet synchroon uit te voeren. Windows Formulieren en gegevensbinding worden vervolgens gebruikt om de resultaten weer te geven in een DataGridView-besturingselement.

Codevoorbeeld

Imports System
Imports System.Collections
Imports System.Collections.ObjectModel
Imports System.Windows.Forms
Imports System.Management.Automation.Runspaces
Imports System.Management.Automation

Namespace Microsoft.Samples.PowerShell.Runspaces

    Class Runspace02

        Shared Sub CreateForm()
            Dim form As New Form()
            Dim grid As New DataGridView()
            form.Controls.Add(grid)
            grid.Dock = DockStyle.Fill

            ' Create an instance of the RunspaceInvoke class.
            ' This takes care of all building all of the other
            ' data structures needed...
            Dim invoker As New RunspaceInvoke()

            Dim results As Collection(Of PSObject) = _
                invoker.Invoke("get-process | sort-object ID")

            ' The generic collection needs to be re-wrapped in an ArrayList
            ' for data-binding to work...
            Dim objects As New ArrayList()
            objects.AddRange(results)

            ' The DataGridView will use the PSObjectTypeDescriptor type
            ' to retrieve the properties.
            grid.DataSource = objects

            form.ShowDialog()

        End Sub 'CreateForm


        ''' <summary>

        ''' <remarks>
        ''' This sample demonstrates the following:
        ''' 1. Creating an instance of the RunspaceInvoke class.
        ''' 2. Using this instance to invoke a PowerShell command.
        ''' 3. Using the output of RunspaceInvoke in a DataGridView
        '''    in a Windows Forms application

        Shared Sub Main(ByVal args() As String)
            Runspace02.CreateForm()

    End Class 'Runspace02
