Running CMD as administrator with an argument from C#

Question

I want to run cmd.exe as administrator with arguments from C# in order to prevent a UAC popup. This is necessary in order to use it as an automated installation

Answer 1

I have been using this code:

        string[] commands = File.ReadAllLines(commandFile);
        foreach (string command in commands)
        {
            Process process = new Process();
            ProcessStartInfo startInfo = new ProcessStartInfo();
            //startInfo.WindowStyle = ProcessWindowStyle.Hidden;
            startInfo.WorkingDirectory = @"C:\Windows\System32";
            startInfo.FileName = "cmd.exe";
            startInfo.Arguments = "/user:Administrator \"cmd /K " + command + "\"";
            process.StartInfo = startInfo;
            process.Start();
        }

As you can see: Trying this code from 'Run' in VS will not give admin, But if you compile this program and run it externally as admin it will. I used this batch file to test privilege level.

@echo off
goto check_Permissions

:check_Permissions
echo Administrative permissions required. Detecting permissions...

net session >nul 2>&1
if %errorLevel% == 0 (
    echo Success: Administrative permissions confirmed.
) else (
    echo Failure: Current permissions inadequate.
)

pause >nul
