使用C＃运行Powershell脚本，异常

Question

I am trying to run a powershell script and I have tried two different approaches but get exceptions from both. What code do I need to add or what do I need to change?

Inside the script am I trying to add a parameter;

Param([string]$MainDoc="not")

First approch with Pipeline() and Command():

public static void RunPowerShell(string filePath, string parameterValue, string parameterName)
        {

            try
            {

                Runspace runspace = RunspaceFactory.CreateRunspace();
                runspace.Open();

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

                Pipeline pipeline = runspace.CreatePipeline();
                Command command = new Command(filePath);

                CommandParameter argParam = new CommandParameter(parameterName, parameterValue);
                command.Parameters.Add(argParam);

                pipeline.Commands.Add(command);

                pipeline.Invoke();
                runspace.Close();

            }catch(Exception e){

                System.Diagnostics.Debug.WriteLine(e.GetBaseException());

            }
        }

Exception from this code:

System.Management.Automation.Host.HostException: Cannot invoke this function because the current host does not implement it.
   at System.Management.Automation.Internal.Host.InternalHostRawUserInterface.ThrowNotInteractive()
   at System.Management.Automation.Internal.Host.InternalHostRawUserInterface.get_ForegroundColor()
   at Microsoft.PowerShell.Commands.ConsoleColorCmdlet.get_ForegroundColor()
   at Microsoft.PowerShell.Commands.WriteHostCommand.PrintObject(Object o)
   at Microsoft.PowerShell.Commands.WriteHostCommand.PrintObject(Object o)
   at Microsoft.PowerShell.Commands.WriteHostCommand.ProcessRecord()
   at System.Management.Automation.Cmdlet.DoProcessRecord()
   at System.Management.Automation.CommandProcessor.ProcessRecord()

Second approach with Process():

public static void RunPowerShell(string filePath, string parameterValue, string parameterName)
        {

            try
            {

                Process p = new Process();

                p.StartInfo.UseShellExecute = false;
                p.StartInfo.RedirectStandardOutput = true;

                p.StartInfo.FileName = filePath;
                p.StartInfo.Arguments = " -" + parameterName + " " + parameterValue;

                p.Start();

            }
            catch (Exception e)
            {

                System.Diagnostics.Debug.WriteLine(e.GetBaseException());

            }
        }

This code gives exception:

System.ComponentModel.Win32Exception (0x80004005): The specified executable is not a valid application for this OS platform.
   at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)
   at System.Diagnostics.Process.Start()

Which I just can not understand since it should be valid for my OS platform.

What have I missed and what should I change? This should be a simple task, just running one Powershell with one argument.

Thnx in advance

Answer 1

The answer that helped were to preface it with Powershell.exe as the code below. filePath contains the path to the powershell script and the parameterValue contains the value for the powershell scripts parameter.

public static void RunPowerShell(string filePath, string parameterValue)
            {

                try
                {

                    Process.Start("C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\Powershell.exe", "" + filePath + " '" + parameterValue + "'");

                }
                catch (Exception e)
                {

                    System.Diagnostics.Debug.WriteLine(e.GetBaseException());

                }
            }
