winform 判断重复检测，是否开启相同应用程序 和 线程异常捕获

 

在Program.cs入口处添加方法：

 

 #region Mutex
        private static Mutex mutex = null;
        /// <summary>
        /// 重复启动检测
        /// </summary>
        /// <remarks>
        /// tips:此逻辑不能放在Main方法中
        /// Mutex会被销毁，需专门封装判断方法
        /// </remarks>
        private static void GlobalMutex()
        {
            // 是否第一次创建mutex
            bool newMutexCreated = false;
            string mutexName = "Global\\" + "GH.DistributeCar_K3";
            try
            {
                mutex = new Mutex(false, mutexName, out newMutexCreated);

                if (!newMutexCreated)
                {
                    MessageDxUtil.ShowTips("另一个窗口已在运行，不能重复运行。");
                    System.Threading.Thread.Sleep(1000);
                    Environment.Exit(1);//退出程序
                }
            }
            catch (Exception ex)
            {
                Console.Write(ex.Message);
                System.Threading.Thread.Sleep(1000);
                Environment.Exit(1);
            }
        }
        #endregion

　　

  #region ThreadExpection
        /// <summary>
        /// UI线程全局异常处理
        /// </summary>
        /// <param name="sender"></param>

        static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
        {
            log4NetUtil.Error("Application_ThreadException", e.Exception);
            string message = $"{e.Exception.Message}\r\n操作发生错误，您需要退出系统么？";
            if (DialogResult.Yes == MessageDxUtil.ShowYesNoAndError(message))
            {
                Environment.Exit(1);
            }
        }
        #endregion

 

 　　　　#region UnhandledException
        /// <summary>
        /// 非UI线程全局异常处理
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            Exception ex = e.ExceptionObject as Exception;
            log4NetUtil.Error(e.ToString(), ex);
            string message = $"{ex.Message}\r\n操作发生错误，您需要退出系统么？";
            if (DialogResult.Yes == MessageDxUtil.ShowYesNoAndError(message))
            {
                Application.Exit();
            }
        }
        #endregion

 

Main调用示例:

 

  　　　　/// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            GlobalMutex();

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            // 全局异常捕获
            Application.ThreadException += Application_ThreadException;
            AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;

            BonusSkins.Register();
            SkinManager.EnableFormSkins();
            UserLookAndFeel.Default.SetSkinStyle("DevExpress Style");
            Application.Run(new FrmMain());
        }
