C # The program runs as an administrator by default.

In the previous blog, I wrote how to update the system time through network time. At that time, I did not test the system successfully. Later I thought about whether it was my operating system (developed on Win8 at that time). At that time, I guess the permission was insufficient and the system time could not be modified. So I ran it once as an administrator and the test was successful! It turned out to be a permission issue.ProgramWhich is run as Administrator by default.Code. Let's see how it is implemented!

 

The program runs as an administrator by default.

 Static   Void Main ( String  [] ARGs ){  /*  ** When the current user is an administrator, directly start the application. * if the user is not an administrator, use the startup object to start the application to ensure that the application runs as an administrator.  */             //  Obtain the Windows User ID for the current Logon System. Security. Principal. windowsidentity identity = System. Security. Principal. windowsidentity. getcurrent ();  //  Create a Windows user topic  Application. enablevisualstyles (); system. Security. Principal. windowsprincipal principal = New  System. Security. Principal. windowsprincipal (identity );  //  Determine whether the current logon user is an administrator              If (Principal. isinrole (system. Security. Principal. windowsbuiltinrole. Administrator )){  //  If it is an administrator, run  Application. enablevisualstyles (); application. Run (  New  Form1 ());}  Else  {  //  Create a startup object System. Diagnostics. processstartinfo startinfo = New System. Diagnostics. processstartinfo ();  //  Set the running File Startinfo. filename = System. Windows. Forms. application. executablepath;  //  Set startup parameters Startinfo. Arguments = string. Join ( "   "  , ArgS );  //  Set the startup action to run as Administrator Startinfo. verb = " RunAs  "  ;  //  If it is not an administrator, start UAC  System. Diagnostics. process. Start (startinfo );  //  Exit  System. Windows. Forms. application. Exit ();}} 

 

 

Open the program. CS file in the program set and replace the code in the main method with the above Code to run the program as an administrator by default.
