Execute PowerShell Script from C# - powershell

Question

I need to make an application which will run Power-Shell and run command Get-Dedupjob, but I received the following error:
the term "Get-Dedupjob" is not recognized as the name of a cmdlet,
function, script file, or operable program.
Although mentioned command works properly when I run this in power-shell (show deduplication jobs).
I suppose that problem could be that program doesn't run command as administrator.
Is there some solution ho to run this as admin? Or where could be the problem?
private void button5_Click(object sender, EventArgs e)
{
// Get-Dedupjob
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript("Get-Dedupjob");
// execute the script
Collection<PSObject> results = pipeline.Invoke();
// close the runspace
runspace.Close();
// convert the script result into a single string
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
textBox1.Text = Convert.ToString(stringBuilder);
}

Answer 1

You should import the corresponding psd1 file

Answer 2

private void button5_Click(object sender, EventArgs e)
{
// Get-Dedupjob
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = rs;
ps.AddCommand("Get-Dedupjob");
// execute the script
Collection<PSObject> results = ps.Invoke();
// convert the script result into a single string
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
textBox1.Text = Convert.ToString(stringBuilder);
// close the runspace
runspace.Close();
}
You will need to create powershell object to run the powershell commands. Following are the using statement imports you need to have for the above to work.
using System.Management.Automation; // Windows PowerShell namespace.
using System.Management.Automation.Runspaces; // Windows PowerShell namespace.
