Write a service that detects once in 5 minutes, whether a process is started or not, and if it is not, the process is started

  Public Partial classService1:servicebase { PublicService1 () {InitializeComponent (); }        protected Override voidOnStart (string[] args) {System.Timers.Timer timer1=NewSystem.Timers.Timer (); Create a timer timer1.

After the creation is finished, you need to install the service to the computer.

The simplest way to install a service:

1. C:\\window\microsoft. Net\ ... 4.5 (3.5,4.0) below InstallUtil.exe and InstallUtilLib.dll copied to the service project Bin\Debug directory

2. Create a new TXT file, enter InstallUtil (-e) WindowsService1.exe Save as Install.bat, and then double-click the file to install the service.

3.1 Enter Services.msc to view the service, find the service just installed, start on it.

3.2 or under CMD, enter the net start service name. such as: net start Service1

The simplest way to uninstall a service: (It's a good idea to stop the service before you uninstall net stop Service1)

1. C:\\window\microsoft. Net\ ... 4.5 (3.5,4.0) below InstallUtil.exe and InstallUtilLib.dll copied to the service project Bin\Debug directory

2. Create a new TXT file, enter Installutil-u WindowsService1.exe Save as Uninstall.bat, and then double-click the file to uninstall the service.

3 Enter Services.msc View service and you can see that the uninstalled service is gone.

Installation and uninstallation services can also be written to a C # program:

Once written to a C # program, running the. exe file directly is OK.
