Winform程序管理员身份启动

winform 程序如何实现启动时自动判断是否为管理员身份启动，并强制用管理员身份启动。

代码如下：

static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            try
            {
                //处理未捕获的异常   
                Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
                //处理UI线程异常   
                Application.ThreadException += Application_ThreadException;
                //处理非UI线程异常   
                AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;

                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                WindowsIdentity identity= WindowsIdentity.GetCurrent();
                WindowsPrincipal principal = new WindowsPrincipal(identity);
                if(principal.IsInRole(WindowsBuiltInRole.Administrator))
                {
                    Application.Run(Form1());
                }
                else
                {
                    ProcessStartInfo startInfo = new ProcessStartInfo();
                    startInfo.UseShellExecute = true;
                    startInfo.WorkingDirectory = Environment.CurrentDirectory;
                    startInfo.FileName=Application.ExecutablePath;
                    //设置启动动作
                    startInfo.Verb = "runas";
                    try
                    {
                        Process.Start(startInfo);
                    }
                    catch (Exception ex)
                    {
                        var strDateInfo = "出现应用程序未处理的异常：" + DateTime.Now + "\r\n";
                        var str = string.Format(strDateInfo + "异常类型：{0}\r\n异常消息：{1}\r\n异常信息：{2}\r\n",
                                      ex.GetType().Name, ex.Message, ex.StackTrace);
                        MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);//进行弹窗提示
                    }
                }
            }
            catch (Exception ex)
            {
                var strDateInfo = "出现应用程序未处理的异常：" + DateTime.Now + "\r\n";
                var str = string.Format(strDateInfo + "异常类型：{0}\r\n异常消息：{1}\r\n异常信息：{2}\r\n",
                              ex.GetType().Name, ex.Message, ex.StackTrace);
                MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);//进行弹窗提示
                //Environment.Exit(0);
            }
        }

        /// <summary>
        ///错误弹窗

            }
            MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);

        }


        static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            var error = e.ExceptionObject as Exception;
            var strDateInfo = "出现应用程序未处理的异常：" + DateTime.Now + "\r\n";
            var str = error != null ? string.Format(strDateInfo + "Application UnhandledException:{0};\n\r堆栈信息:{1}", error.Message, error.StackTrace) : string.Format("Application UnhandledError:{0}", e);
            MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
            //Environment.Exit(0);
        }
