Runspace02 (VB.NET) コード サンプル

Runspace02 サンプルの VB.NET ソース コードを次に示します。 このサンプルでは、System.Management.Automation.RunspaceInvoke クラスを使用して、Get-Process コマンドレットを同期的に実行します。 その後、Windows フォームとデータ バインディングを使用して、DataGridView コントロールに結果を表示します。

        ''' <summary>
        ''' This sample uses the RunspaceInvoke class to execute

        ''' <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
        ''' </remarks
