I recently came across a situation where I wanted to restart my program with administrator privileges if it was run with no parameters so the program could execute an install sequence.
I used the following code in a .NET 7.0 Console application...
using System.Diagnostics;
using System.Security.Principal;
class Stuff
{
static void Install()
{
try
{
//check if we are running as administrator currently
if (!new WindowsPrincipal(WindowsIdentity.GetCurrent()).IsInRole(WindowsBuiltInRole.Administrator))
{
//Start new process as administrator. Environment.ProcessPath is the path of what we are currently running.
Process.Start(new ProcessStartInfo { FileName = Environment.ProcessPath, UseShellExecute = true, Verb = "runas" });
//Exit current process
Environment.Exit(0);
}
}
//if user selects "no" from adminstrator request.
catch
{
Console.WriteLine("Administrative rights are required for installing this application.\nPress any key to exit.");
Console.ReadKey(true);
Environment.Exit(0);
}
//Do stuff...
Console.WriteLine("Install complete\nPress any key to exit\n");
Console.ReadKey(true);
Environment.Exit(0);
}
public static void Main(string[] args)
{
if (args.Length == 0)
Install();
else
{
//Do stuff...
}
}
}
