Windows 7和Vista UAC - 以編程方式請求C中的高程＃

Question

我有一個程序只需要在非常罕見的情況下提升管理員權限，因此我不想設置我的清單以要求永久提升。

如何僅在需要時以編程方式請求提升？

我使用C＃

Answer 1

WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()); 
bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator); 

if (!hasAdministrativeRight) 
{ 
    RunElevated(Application.ExecutablePath); 
    this.Close(); 
    Application.Exit(); 
} 

private static bool RunElevated(string fileName) 
{ 
    //MessageBox.Show("Run: " + fileName); 
    ProcessStartInfo processInfo = new ProcessStartInfo(); 
    processInfo.Verb = "runas"; 
    processInfo.FileName = fileName; 
    try 
    { 
     Process.Start(processInfo); 
     return true; 
    } 
    catch (Win32Exception) 
    { 
     //Do nothing. Probably the user canceled the UAC window 
    } 
    return false; 
}
