如何在 ZD7EFA19FBE7D3972FD5ADB6024223D74 中将 powershell 脚本传递给 Windows PowerShell 主机

Question

I would like to use the methods of Windows PowerShell Host on C# project (.NETFramework) I had installed System.Management.Automation.dll on my project to run the commands of PowerShell on C#.

我的目标是传递我的 ps1 文件，其中包含：

$ProcessName = "Notepad"
$Path = "D:\FolderName\data.txt"

$CpuCores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors 
$Samples = (Get-Counter "\Process($Processname*)\% Processor Time").CounterSamples 
$Samples | Select @{Name="CPU %";Expression={[Decimal]::Round(($_.CookedValue / $CpuCores), 2)}} | Out-File -FilePath $Path -Append 

到 C# 中的本机实现。 这将返回进程的 CPU 使用率。 I want to use the PowerShell Object to avoid to have the ps1 file, because I want to write the previous commands on C# using the System.Management.Automation.PowerShell class, example:

PowerShell powerShellCommand = PowerShell.Create();
powerShellCommand.AddCommand("Get-WMIObject");
powerShellCommand.AddArgument("Win32_ComputerSystem");
powerShellCommand.AddArgument("NumberOfLogicalProcessors ");

您知道如何将其转移到 powershell Object 和 C# 上的方法吗？

您可以将参数块（ param() ）添加到脚本并调用它：

const string script = @"
    param(
        [string] $ProcessName,
        [string] $Path
    )

    $CpuCores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors
    $Samples = (Get-Counter ""\Process($ProcessName*)\% Processor Time"").CounterSamples
    $Samples |
        Select @{Name=""CPU %"";Expression={[Decimal]::Round(($_.CookedValue / $CpuCores), 2)}} |
        Out-File -FilePath $Path -Append";

PowerShell powerShellCommand = PowerShell.Create();
powerShellCommand
    .AddScript(script)
    .AddParameters(new PSPrimitiveDictionary
    {
        { "ProcessName", "Notepad" },
        { "Path", @"D:\FolderName\data.txt" }
    })
    .Invoke();
