Answer 1

You can embed this manifest into your application.

<?xml version="1.0" encoding="utf-8" ?>  <asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">     <assemblyIdentity version="1.0.0.0" name="MyApplication" />     <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">         <security>             <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">                 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />             </requestedPrivileges>         </security>     </trustInfo> </asmv1:assembly>

Here is the sample code to run your application as admin.

ProcessStartInfo proc = new ProcessStartInfo(); proc.UseShellExecute = true; proc.WorkingDirectory = Environment.CurrentDirectory; proc.FileName = Application.ExecutablePath; proc.Verb = "runas"; try {     Process.Start(proc); } catch {     // The user refused the elevation.     // Do nothing and return directly ...     return; } Application.Exit();  // Quit itself 

Set the ProcessStartInfo.Verb to “runas” will let it run as admin. Here is related FAQ
