I having issues with passing arguments to PowerShell via C#
I am getting the following exception:
"A command that prompts the user failed because the host program or the command type does not support user interaction. Try a host program that supports user interaction, such as the Windows PowerShell Console or Windows PowerShell ISE, and remove prompt-related commands from command types that do not support user interaction, such as Windows PowerShell workflows"
cs:
private static void RunPowershellScript(string scriptFile, string scriptParameters)
{
string scriptParameters = "param1 param2";
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
Command scriptCommand = new Command(scriptFile);
Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
foreach (string scriptParameter in scriptParameters.Split(' '))
{
CommandParameter commandParm = new CommandParameter(null, scriptParameter);
commandParameters.Add(commandParm);
scriptCommand.Parameters.Add(commandParm);
}
pipeline.Commands.Add(scriptCommand);
Collection<PSObject> psObjects;
psObjects = pipeline.Invoke();
}
ps:
Function Foo ($arg1, $arg2)
{
Write-Host $arg1
Write-Host $arg2
}
Foo $args[0] $args[1]
What am i missing here? how can i make this work?
The exception is not about arguments. Either do not use commands that require host UI implemented ( Write-Host
included) or implement you own custom host ( PSHost
) and this UI ( PSHostUserInterface
). Here is the example of a simple host (and there is much more on MSDN about this, if you choose this way): http://msdn.microsoft.com/en-us/library/windows/desktop/ee706559(v=vs.85).aspx
For simple tasks implementing a host with UI is too much, perhaps. You may consider simply to define a function Write-Host
with the same arguments and implement it so that it works in your specific case (eg does [Console]::WriteLine(...)
). This function should be defined in the script or better made available for it in a different way, eg invoke another script with it defined in the global scope.
PS And if you have your custom host then use one of the CreateRunspace()
overloads that takes a host instance as an argument in order to link the host and the runspace.
