如何在C#表单中设置Powershell ExecutionPolicy？

using System;
using System.Management.Automation;

namespace PowerShellExecutionPolicy
{
    class Program
    {
        static void Main(string[] args)
        {
            using (PowerShell ps = PowerShell.Create())
            {
                ps.AddCommand("Set-ExecutionPolicy")
                    .AddParameter("ExecutionPolicy", "RemoteSigned")
                    .AddParameter("Scope", "CurrentUser")
                    .AddParameter("Force");

                ps.Invoke();
            }

            Console.WriteLine("Powershell ExecutionPolicy has been set successfully.");
            Console.ReadLine();
        }
    }
}
