程序发布后，必须以管理员身份登陆

    项目中打包程序，在后续更新时需要管理员身份运行，固将程序运行时，使用管理员运行。

作如下设置

1）在App.cs中增加以下代码：

        /// 

        /// 检查是否是管理员身份
        /// 
        private void CheckAdministrator()
        {
            var wi = WindowsIdentity.GetCurrent();
            var wp = new WindowsPrincipal(wi);

            bool runAsAdmin = wp.IsInRole(WindowsBuiltInRole.Administrator);

            if (!runAsAdmin)
            {
                // It is not possible to launch a ClickOnce app as administrator directly,
                // so instead we launch the app as administrator in a new process.
                var processInfo = new ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase);

                // The following properties run the new process as administrator
                processInfo.UseShellExecute = true;
                processInfo.Verb = "runas";

                // Start the new process
                try
                {
                    Process.Start(processInfo);
                }
                catch (Exception ex)
                {
                    ex.WriteLog();
                }

                // Shut down the current process
                Environment.Exit(0);
            }
        }

2）重写 OnStartup 函数 

protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            CheckAdministrator();

//如果不是管理员，程序会直接退出。

StartupUri = new Uri("MainWindow.xaml", UriKind.RelativeOrAbsolute); }
