How to pass arguments to a powershell script from C# program?

Question

I have a script file sample.ps1 which has the following command :

copy-item C:\source -destination C:\destination.

Instead of hard coding the value for source and destination I want to pass it as arguments to the script.

copy-item $source -destination $destination.

I want to call this script from a stand alone client and pass the source and destination as parameters. I have the following program to execute the script file :

            string shellUri = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
            string userName = "MachineName\\Administrator";
            string password = "Password";
            SecureString securePassword = new SecureString();

            foreach (char c in password)
            {
                securePassword.AppendChar(c);
            }
            PSCredential credential = new PSCredential(userName, securePassword);
            WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, "machinename", 5985, "/wsman", shellUri, credential);
            using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
            {

                runspace.Open();
        String file = "C:\\scripts\\Sample.ps1";
                Pipeline pipeline = runspace.CreatePipeline();

                pipeline.Commands.AddScript(System.IO.File.ReadAllText(file));
        }

I want to pass the parameters to the script Sample.ps1 through the C# program. How is that possible?

Instead of reading the file and using Commands.AddScript to inject its contents as text, I'd rather use the Commands.Add method to add a command that would call the Sample.ps1 script directly, as a file:

pipeline.Commands.Add( "C:\\dirWithNoSpaces\\scripts\\Sample.ps1 -param1 value1");

but be careful about escaping.. I've just read that if there any spaces in the path, it has to be quoted:

pipeline.Commands.Add( "&\"C:\\dir with spaces\\scripts\\Sample.ps1\" -param1 value1");

However, if you'd like to keep it as you have it now, you might look for some ways to add 'parameters' in Pipeline or Runspace objects. For example, I've just found this: Runspace.InitialSessionState - you inject some initial variables to the runtime environment, so you could use it to pass values to inlined-scripts. However, the values will already be in-variables, not in the ARGV or such.

FYI: I have not tried it. I'm basing on this question. It should work, but still I just guess.

I tried the above method without parameter, but I am getting the following error : 'Unhandled Exception: System.Management.Automation.RemoteException: The term 'C:\scripts\Sample.ps1' is not recognized as the name of a cmdlet, function, scrip t file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.'
