从c应用程序运行powershell

你好，在powershell中有一个包含21行代码的文件。我需要一种用c#中的按钮运行这个文件的方法。我在Visual Studio 2010中使用c#。如果有实现的方法，请告诉我。

$Proc = Get-Process | Sort-Object CPU -Descending
$cores = Get-WmiObject Win32_processor
$memory = Get-WmiObject Win32_OperatingSystem
$Total = 10
$num = 1

If ($num -gt $Total) {
    break #break the loop
}
[string] $strID=[System.Convert]::ToString($objItm.ID)
[string] $strProcessName=[System.Convert]::ToString($objItm.ProcessName)
[string] $strCPU=[System.Convert]::ToString($objItm.CPU)
[string] $strNUM=[System.Convert]::ToString($num)
$info=$strNUM+"-"+$strID+"-"+$strProcessName+"-"+$strCPU
$num += 1
$info|Add-Content c://scripts/prueba.txt
}
//Code c#
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create(); 
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open(); RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline(); 
pipeline.Commands.Add(scriptFile)
Execute PowerShell script results = pipeline.Invoke();

例如，我需要按下一个按钮，使脚本发生
