此示例演示如何使用 System.Management.Automation.PowerShell 类同步运行 Get-Process 和 Sort-Object cmdlet。
Get-Process cmdlet 返回本地计算机上运行的每个进程的 system.Diagnostics.Process 对象，Sort-Object 根据其 System.Diagnostics.Process.Id* 属性对对象进行排序。 这些命令的结果通过使用 System.Windows.Forms.DataGridView 控件显示。
要求
此示例需要 Windows PowerShell 2.0。
演示
此示例演示了以下内容。
创建 System.Management.Automation.PowerShell 对象以运行命令。
将命令添加到 System.Management.Automation.PowerShell 对象的管道。
同步运行命令。
使用 System.Windows.Forms.DataGridView 控件在 Windows 窗体应用程序中显示命令的输出。
示例
此示例在 Windows PowerShell 提供的默认运行空间中同步运行 Get-Process 和 Sort-Object cmdlet。 输出使用 System.Windows.Forms.DataGridView 控件显示在窗体中。
