c# - Elevating process privilege programmatically? -

-

i'm trying install service using installutil.exe invoked through process.start. here's code:

processstartinfo startinfo = new processstartinfo (m_strinstallutil, strexepath); system.diagnostics.process.start (startinfo);

where m_strinstallutil qualified path , exe "installutil.exe" , strexepath qualified path/name service.

running command line syntax elevated command prompt works; running app (using above code) not. assume i'm dealing process elevation issue, how run process in elevated state? need @ shellexecute this?

this on windows vista. running process in vs2008 debugger elevated admin privilege.

i tried setting startinfo.verb = "runas"; didn't seem solve problem.

you can indicate new process should started elevated permissions setting verb property of startinfo object 'runas', follows:

startinfo.verb = "runas";

this cause windows behave if process has been started explorer "run administrator" menu command.

this mean uac prompt come , need acknowledged user: if undesirable (for example because happen in middle of lengthy process), you'll need run entire host process elevated permissions create , embed application manifest (uac) require 'highestavailable' execution level: cause uac prompt appear app started, , cause child processes run elevated permissions without additional prompting.

edit: see edited question state "runas" didn't work you. that's strange, should (and me in several production apps). requiring parent process run elevated rights embedding manifest should work, though.
