Question

I am writing PS script that will be integrated with the C# based Windows Form Application. This is what I have tried/done already:

1. I am able to run PS scripts through the runspace and pipeline, however i encounter the error while I am trying to run the script that uses functions, saying: ” Cannot invoke this function because the current host does not implement it.”

2. I have researched the problem and I have found very few people who had encoutered similar problem, however one of the solutions underlined that I need to use (add) the following $ConfirmPreference = “None”, ,-Confirm:$false, -Force

3. However when I tried that the following error message appeared: ” Missing expression after unary operator ‘-‘. “ You can see that I have tried to concatenate the strings by assigning them to the variables, but that did not help. I do not have any idea how to solve it, has anyone got any ideas? Any help will be much appreciated.

      // create Powershell runspace
      Runspace runspace = RunspaceFactory.CreateRunspace();
      // open it
      runspace.Open();
   
      // create a pipeline and feed it the script text
      Pipeline pipeline = runspace.CreatePipeline();
   
      //allow the functions to be exec
      string sa = "$ConfirmPreference = \"None\" ";
      string se = " -Confirm:$false -Force";
      string s = sa +scriptText + se;
      pipeline.Commands.AddScript(s);
   

Answer 1

-Confirm:$false -Force are meant to be function parameters, they don’t exist on their own.

Do-Something -param1 'foo' -Confirm:$false -Force

But even if you modify every function call with these parameters, it probably won’t solve all of your issues. See here for more options.
