Elevating privileges doesn't work with UseShellExecute=false

Question

I want to start a child process (indeed the same, console app) with elevated privileges but with hidden window.

I do next:

var info = new ProcessStar         


        

Answer 1

In my case, it was ok to get the outputs once the elevated child process is done. Here's the solution I came up. It uses a temporary file :

var output = Path.GetTempFileName();
var process = Process.Start(new ProcessStartInfo
{
    FileName = "cmd",
    Arguments = "/c echo I'm an admin > " + output, // redirect to temp file
    Verb = "runas", // UAC prompt
    UseShellExecute = true,
});
process.WaitForExit();
string res = File.ReadAllText(output);
// do something with the output
File.Delete(output);
