Examples of Windows services
Here is a test case, the service named Service1 Black is automatically generated, the red part of the code I added, green for me to add the comment, this case has no other meaning, just insert the record into the database.
Using System;
Using System.Collections;
Using System.ComponentModel;
Using System.Data;
Using System.Diagnostics;
Using System.ServiceProcess;
Using System.Configuration.Install;
Using Sysdata.db; Namespace Servertest

This call is required by the Windows.Forms Component Designer.
InitializeComponent (); TODO: Add any initialization after the initcomponent call
} Main entry point of the process
static void Main ()
{
System.serviceprocess.servicebase[] ServicesToRun;
Multiple User services can be run in the same process. To add
Another service is added to this process, please change the downstream
To create another service object. For example
//
ServicesToRun = new system.serviceprocess.servicebase[] {new Service1 (), New MySecondUserService ()};
//
ServicesToRun = new system.serviceprocess.servicebase[] {new Service1 ()}; System.ServiceProcess.ServiceBase.Run (ServicesToRun);
} <summary>
Designer supports required methods-do not use the Code Editor
Modify the contents of this method.
