I am running powershell script from c#.
string scriptPath = "/script/myscript.ps1";
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptPath);
Collection<PSObject> results = pipeline.Invoke();
for example if my myscript.ps1 file below;
$test=4
$test++
$test
How to get the variable test value after executing the script. I need to get that value to my c# program.
I know I am late to this, but in your script, you need to add global: in front of the variable you want to return in the Powershell script, so for example:
$global:test = 4
in Powershell script. In C# after you open the runspace, invoke the policy changer, set up the pipline, you do
var result = runspace.SessionStateProxy.PSVariable.GetValue("test");
string variable_to_return_from_ps_script = "test";
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
//
// here you write the code to invoke the PS script, pipeline, pass parameters etc...
// just like the code you already have
//
// and here's how you retrieve a variable test from PS
var out_var = runspace.SessionStateProxy.PSVariable.GetValue(variable_to_return_from_ps_script);
Console.WriteLine("Variable ${0} value is: ", variable_to_return_from_ps_script);
Console.WriteLine(out_var.ToString());
