You ll want to modify the manifest that gets embedded in the program  This works on Visual nbsp Studio nbsp 2008 and higher  Project   Add New Item  select  Application Manifest File   Change the  lt requestedExecutionLevel gt  element to     lt requestedExecutionLevel level  requireAdministrator  uiAccess  false    gt    The user gets the UAC prompt when they start the program  Use wisely  their patience can wear out quickly

THIS DOES NOT FORCE APPLICATION TO WORK AS ADMINISTRATOR   This is a simplified version of the this answer  above by  NG public bool IsUserAdministrator         try               WindowsIdentity user   WindowsIdentity GetCurrent            WindowsPrincipal principal   new WindowsPrincipal user           return principal IsInRole WindowsBuiltInRole Administrator             catch               return false

Another way of doing this  in code only  is to detect if the process is running as admin like in the answer by  NG   And then open the application again and close the current one   I use this code when an application only needs admin privileges when run under certain conditions  such as when installing itself as a service  So it doesn t need to run as admin all the time like the other answers force it too   Note in the below code NeedsToRunAsAdmin is a method that detects if under current conditions admin privileges are required  If this returns false the code will not elevate itself  This is a major advantage of this approach over the others   Although this code has the advantages stated above  it does need to re-launch itself as a new process which isn t always what you want   private static void Main string   args        if  NeedsToRunAsAdmin    amp  amp   IsRunAsAdmin                  ProcessStartInfo proc   new ProcessStartInfo            proc UseShellExecute   true          proc WorkingDirectory   Environment CurrentDirectory          proc FileName   Assembly GetEntryAssembly   CodeBase           foreach  string arg in args                        proc Arguments    String Format     0       arg                      proc Verb    runas            try                       Process Start proc                     catch                       Console WriteLine  This application requires elevated credentials in order to operate correctly                         else                 Normal program logic             private static bool IsRunAsAdmin         WindowsIdentity id   WindowsIdentity GetCurrent        WindowsPrincipal principal   new WindowsPrincipal id        return principal IsInRole WindowsBuiltInRole Administrator

I implemented some code to do it manually   using System Security Principal  public bool IsUserAdministrator         bool isAdmin      try               WindowsIdentity user   WindowsIdentity GetCurrent            WindowsPrincipal principal   new WindowsPrincipal user           isAdmin   principal IsInRole WindowsBuiltInRole Administrator             catch  UnauthorizedAccessException ex                isAdmin   false            catch  Exception ex                isAdmin   false            return isAdmin

As per   lt requestedExecutionLevel level  highestAvailable  uiAccess  false    gt    you will want to add an application manifest if you don t already have one or don t know how to add one  As some projects don t automatically add a separate manifest file  first go to project properties  navigate to the Application tab and check to make sure your project is not excluding the manifest at the bottom of the tap    Next  right click project Add new Item Last  find and click Application Manifest File

You can create the manifest using ClickOnce Security Settings  and then disable it   Right click on the Project - gt  Properties - gt  Security - gt  Enable ClickOnce Security Settings   After you clicked it  a file will be created under the Project s properties folder called app manifest once this is created  you can uncheck the Enable ClickOnce Security Settings option  Open that file and change this line     lt requestedExecutionLevel level  asInvoker  uiAccess  false    gt    to     lt requestedExecutionLevel  level  requireAdministrator  uiAccess  false    gt    This will make the program require administrator privileges

Adding a requestedExecutionLevel element to your manifest is only half the battle  you have to remember that UAC can be turned off  If it is  you have to perform the check the old school way and put up an error dialog if the user is not administrator   call IsInRole WindowsBuiltInRole Administrator  on your thread s CurrentPrincipal
