how to use c# run batch file as Administrator to install windows services

Question

I have create a batch file which use to install my program as windows services. Content of the batch file:

> C:\Project\Test\InstallUtil.exe
> "C:\Project\Test\ROServerService\Server\bin\Debug\myservices.exe"

Currently it needs the user to right-click the batch file and 'Run as Administrator' in order to success. How do we avoid 'Run as Administrator'? I mean can we use some command in the batch file to tell Windows to run this batch file as administrator?

Answer 1

This way worked for me in the past:

string exe = @"C:\Project\Test\InstallUtil.exe";
string args = @"C:\Project\Test\ROServerService\Server\bin\Debug\myservices.exe";
var psi = new ProcessStartInfo();
psi.CreateNoWindow = true; //This hides the dos-style black window that the command prompt usually shows
psi.FileName = @"cmd.exe";
psi.Verb = "runas"; //This is what actually runs the command as administrator
psi.Arguments = "/C " + exe + " " + args;
try {
    var process = new Process();
    process.StartInfo = psi;
    process.Start();
    process.WaitForExit();
}
catch (Exception){
    //If you are here the user clicked decline to grant admin privileges (or he's not administrator)
}

Note that I'm running the commands in your batch file directly here, but of course you can also run the batch file itself:

string bat = @"C:\path\to\your\batch\file.bat";
var psi = new ProcessStartInfo();
psi.CreateNoWindow = true; //This hides the dos-style black window that the command prompt usually shows
psi.FileName = @"cmd.exe";
psi.Verb = "runas"; //This is what actually runs the command as administrator
psi.Arguments = "/C " + bat;
