[C#]限制程序只能运行一個实例 （防多开）

    Process[] processes = Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName); // no ".exe"
    if (processes.Length > 1)
    {
      log.Fatal("Another instance is running.");
      Environment.Exit(1);
    }
    

    Process[] processes = Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName); // no ".exe"
    if (processes.Length > 1)
    {
      log.Fatal("Another instance is running.");
      Environment.Exit(0);
    }
