Executing a PowerShell script from C# with Parameters

[Jose_49]

Sup. I'm adapting this solution to a Windows Forms solution. So far I've been able to execute the `Get-WUList` command with no problems. But it doesn't seem to go well with the `Hide-WUUpdate`. This is what I've tried so far:

 

    public class PowerShellController : IPowerShell
    {

        //Created at a global scope so anyone can fetch it.
        InitialSessionState initial;
        RunspaceInvoke scriptInvoker;
        Runspace runspace;
        PowerShell ps;

        //The View to Control
        IView view;

        //The Helper GridViewProcessor class
        IGridViewProcessor gp;

        //Initializing the Controller - Loads the Module.
        public PowerShellController()
        {
            initial = InitialSessionState.CreateDefault();
            initial.ImportPSModule(new string[] { @"C:\Users\Jose\Documents\WindowsPowerShell\Modules\PSWindowsUpdate\PSWindowsUpdate.psd1" });
            scriptInvoker = new RunspaceInvoke();
            scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted -Scope Process");

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

            using (ps = PowerShell.Create())
            {
                ps.Runspace = runspace;
            }

            //Console.WriteLine("Please Wait. This will take a while to load.");

        }


        public void SetView(IView view, IGridViewProcessor gp)
        {
            this.view = view;
            this.gp = gp;
        }


        public void GetAvailableUpdates()
        {

            MessageBox.Show("Ok. The program will kind of hang. This is normal." +
                            "This Means that it will start looking for updates "
                );

            IEnumerable<PSObject> WUList; //Placeholder for the PS Executed Command

            using (ps = PowerShell.Create())
            {
                //Adds the PowerShell Command
                ps.Commands.AddCommand("Get-WUList");
                //Executes the PowerShell command
                WUList = ps.Invoke();
            }
            
            //Loads the Model - Can be later on rewritten for Ninject Support.
            List<WindowsUpdate> model = new List<WindowsUpdate>();
            int id = 1;
            foreach (PSObject result in WUList)
            {
                WindowsUpdate item = new WindowsUpdate
                {
                    Id = id,
                    Name = result.Members["Title"].Value.ToString(),
                    Size = result.Members["Size"].Value.ToString(),
                    Type = UpdateType.Undefined,

                };
                model.Add(item);
                id++; //Icnrease ID count
                //Console.WriteLine("Update Name {0} --- Size: {1}", result.Members["Title"].Value.ToString(), result.Members["Size"].Value.ToString());
            }

            //Adds it to the view:
            view.AddUpdateToGrid(model);
        }

        public void HideSelectedUpdates(DataGridView grid)
        {
            //Gets SelectedUpdates to the WindowsUpdate model
            var SelectedUpdates = gp.GetSelectedUpdates(grid);
            using (ps = PowerShell.Create())
            {
                foreach (var update in SelectedUpdates)
                {
                    ps.Commands.Clear();
                    ps.Commands.AddCommand("Hide-WUUpdate").AddParameter("Title",update.Name).AddParameter("Confirm", false);
                                        
                    //ps.Commands.AddCommand("Hide-WUUpdate -Title \""+update.Name+"\"");
                   var result = ps.Invoke();
                    
                }

            }

            MessageBox.Show("Updates Have been hidden");

        }

    }

The method I can't seem to work is the `HideSelectedUpdates(DataGridView grid)`.

Script gets executed and no exceptions are thrown, but it doesn't seem to reflect any changes at all.

Any suggestions?

Your ps.Invoke is returning result .... is there any clues in that?

So far, the "errors" key are throwing no values at all!
