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
Imports System.Collections.Generic
Imports System.Text
Imports System.Management.Automation
Imports System.Management.Automation.Host
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.
' This takes care of all building all of the other
' data structures needed...
Dim invoker As RunspaceInvoke = New RunspaceInvoke()
Console.WriteLine("Process HandleCount")
Console.WriteLine("--------------------------------")
' Now invoke the runspace and display the objects that are
' returned...
For Each result As PSObject In invoker.Invoke("Get-Process")
Console.WriteLine("{0,-20} {1}", _
result.Members("ProcessName").Value, _
result.Members("HandleCount").Value)
Next
System.Console.WriteLine("Hit any key to exit...")
System.Console.ReadKey()
