C# start a application as admin with password

I am new to programming with C# and am looking for an answer. I have already looked around on this website, but I'm not entirely sure how to do it. For my work I am developing a desktop application to restart devices / drivers in Windows 10. I do this with devcon, but when i start devcon as a administrator it asks for a username and password. I know the username and password, but it will not start as a admin. The code below works, but asks for admin login details.

//Test Devcon with admin rights
Process proc = new Process();
ProcessStartInfo PSI =
new ProcessStartInfo(@"C:\Devon\devcon.exe");
PSI.WindowStyle = ProcessWindowStyle.Hidden;
PSI.UseShellExecute = true;
PSI.Verb = "runas";
proc.StartInfo = PSI;
proc.Start();

// Disable WIFI
PSI.Arguments = (@"disable *VEN_168C");
Process.Start(PSI);

System.Threading.Thread.Sleep(3000);

//Enable WIFI
PSI.Arguments = (@"enable *VEN_168C");
Process.Start(PSI);
