Runspace01 (VB.NET) 代码示例

下面是 创建运行指定命令的控制台应用程序中所述的运行空间的代码示例。 为此,应用程序调用一个运行空间,然后调用一个命令。 (请注意,此应用程序不指定运行空间配置信息,也不会显式创建管道。调用的命令是 Get-Process cmdlet。

代码示例

Imports System.Management.Automation.Runspaces

Namespace Microsoft.Samples.PowerShell.Runspaces

    Module Runspace01
        ' <summary>
        ' This sample uses the RunspaceInvoke class to execute
        ' the Get-Process cmdlet synchronously. The name and
        ' handlecount are then extracted from  the PSObjects
        ' returned and displayed.
        ' </summary>
        ' <param name="args">Unused</param>
        ' <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 PSObject to extract properties from the objects
        '    returned by this command.
        ' </remarks>
        Sub Main()
            ' Create an instance of the RunspaceInvoke class.

            ' data structures needed...

            Console.WriteLine("Process              HandleCount")

            ' returned...
