Create an name.exe.manifest







level="requireAdministrator"

uiAccess="false"/>







VS Command prompt : mt.exe -manifest menu.exe.manifest -outputresource:menu.exe;#1



Post build event:

"$(DevEnvDir)\..\Tools\Bin\mt.exe" -manifest "$(ProjectDir)$(TargetName).exe.manifest" -outputresource:"$(TargetDir)$(TargetName).exe;#1"



For VS2010,

Project Properties > Configuration Properties > Linker > Manifest File

Change the 'UAC Execution Level' to the desired value.

Access command line arguments in C#

There are two common ways to read command line arguments in C#. First, you can override the Main method with an array of strings, which are command line arguments. For example, the following code loops through the command line arguments and print them on the console.




static void Main(string[] args)



{



foreach(string arg in args)



{



Console.WriteLine(arg);



}



Console.ReadLine();



}



You can do so using the Environment class, which has a static method called GetCommandLineArgs, which returns an array of strings containing the arguments. The following code reads the command line arguments using Environment.GetCommandLineArgs method.




foreach (string arg in Environment.GetCommandLineArgs())



{



Console.WriteLine(arg);



}

Run the application in admin mode

You'll want to modify the manifest that gets embedded in the program. Works on VS2008 + 2010: Project + Add New Item, select "Application Manifest File". Change the element to:

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 a error dialog if the user is not admin (Call IsInRole(WindowsBuiltInRole.Administrator) on your threads CurrentPrincipal)
