从PowerShell捕获输出而不使用PowerShell对象

Question

在我的c＃app中有一些按钮，当用户点击此按钮时，应用程序会运行一个PowerShell脚本。

弹出一个powershell窗口，用户在电源外壳窗口中看到结果。

我正试图从powershell窗口获取输出，并在我的应用程序的某些文本框中显示输出。

这是我的代码：

int ExecuteScript(string path)
        {
            // this is the script that i would run in a process and would monitor. You don't need to put anything
            // in the script just put it to sleep for like 1 minute or so.
            string command; 
            RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
            Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
            runspace.Open();

            RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
            scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

            command = "$job = [Diagnostics.Process]::Start(\"powershell.exe\", \"" + path + "\")"; // * if $null is passed it needs to be '$null' *
            scriptInvoker.Invoke(command);

            int pid = 0;
            foreach (PSObject result in scriptInvoker.Invoke("$job.id"))
            {
                if (result != null)
                {

                    pid = Convert.ToInt32(result.ToString());
                }
            }
            return pid;

        }

对于某些版本问题，我没有使用PowerShell对象来运行脚本
