我想在C++编程中执行PowerShell命令。我已经编辑好了需要运行的命令语句。PowerShell_CMD、XML_File

这样的代码怎么样：system("powershell 'echo \"hello from powershell\"'");？不过我不知道对于比这更复杂的东西有多实用... - Blaze

我认为对于像您图像中展示的这样复杂的内容，倾向于导出一个临时的ps1文件是明智的。接着，可以将@Blaze的答案调整为“system("powershell -f temp.ps1");” - Matt R

我这里的假设是您正在尝试将-auto添加到参数中。在审查提供的图像后，我也会更改PowerShell代码。

$task = Get-ScheduledTask "Test"
$items = @{}
if ($task.Actions.Execute -ne $null) {$items.Add('Execute', "$($task.Actions.Execute)")} 
$items.Add('Argument', "$($task.Actions.Arguments) -auto") 
if ($task.Actions.WorkingDirectory -ne $null) {$items.Add('WorkingDirectory',"$($task.Actions.WorkingDirectory)")} 
$action = New-ScheduledTaskAction @items
$task.Actions = $action
Set-ScheduledTask -InputObject $task

更简单易懂。

要在c++中运行此代码，您应将代码转储到临时文件中。

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ofstream file;
    file.open("test.ps1");

    string newArg = "-auto";
    string powershell;
    powershell = "$task = Get-ScheduledTask \"Test\"\n";
    powershell += "$items = @{}\n";
    powershell += "if ($task.Actions.Execute -ne $null) {$items.Add('Execute', \"$($task.Actions.Execute)\")} \n";
    powershell += "$items.Add('Argument', \"$($task.Actions.Arguments) " + newArg + "\") \n"; // 'Argument' not a typo
    powershell += "if ($task.Actions.WorkingDirectory -ne $null) {$items.Add('WorkingDirectory',\"$($task.Actions.WorkingDirectory)\")} \n";
    powershell += "$action = New-ScheduledTaskAction @items\n";
    powershell += "$task.Actions = $action\n";
    powershell += "Set-ScheduledTask -InputObject $task\n";
    file << powershell << endl;
    file.close();

    system("powershell -ExecutionPolicy Bypass -F test.ps1");

    remove("test.ps1");
}
