Windows Embedded POSReady 2009上的C＃Process.Start（）管理员特权

Question

I am attempting to call a batch file with administrator privileges in some C# code using System.Diagnostic 's Process.Start() as mentioned here: How to start a Process as administrator mode in C# .

I call the built executable from an elevated command prompt as well as with runas /user:administrator program.exe . The subprocess succeeds when called outside of my program, but fails at its administrator tasks when called by my program.

I have attempted using a manifest and setting the Process.Verb = "runas" , but no luck there.

The subprocess installs a driver and my program verifies the version number if that's relevant.

Thank you for the help!

Answer 1

Make sure you have the following lines in your application's manifest:

  <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
  </requestedPrivileges>

Your application will spawn other processes at the same elevation level as itself. Meaning that if your application runs as a non-administrator, every process it spawns will run without administrative permissions, too.

Make sure your parent application has elevated permissions before you start your batch file.

Answer 2

Turns out administrator privileges are only given to executables when using runas , so you can't call the batch file directly. Instead of p.StartInfo.FileName = program.bat , you should call it with p.StartInfo.FileName = "cmd.exe" and p.StartInfo.Arguments = " /C ..." .
