This article mainly explains "how to create a Windows service program in C #". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to create a Windows service program in C#".

C # create Windows service program:

Before I introduce how to create a Windows service program in C #, let me introduce the namespaces and class libraries related to Windows services under the .net framework. The .net framework greatly simplifies the creation and control of Windows service programs, thanks to the powerful class libraries in its namespace. The namespaces associated with Windows service programs involve two: System.ServiceProcess and System.Diagnostics.

To create a basic C # Windows service program diagram, we only need to use the System.ServiceProcess namespace under the .net framework and its four classes: ServiceBase, ServiceInstaller, ServiceProcessInstaller, and ServiceController, whose architecture can be seen in C # to create a Windows service program diagram:

The Service Base class defines some functions that can be overloaded by its subclasses. Through these overloaded functions, the service control manager can control the Windows service program. These functions include: OnStart (), OnStop (), OnPause (), and OnContinue (). And subclasses of the ServiceBase class can also overload the OnCustomCommand () function to perform specific operations. By overloading some of the above functions, we have completed a basic framework for creating Windows service programs in C #. The overloading methods of these functions are as follows:

Protected override void OnStart (string [] args) {} protected override void OnStop () {} protected override void OnPause () {} protected override void OnContinue () {}

The ServiceBase class also provides us with properties that are necessary for any Widnows service program. The ServiceName attribute specifies the name of the Windows service, through which the Windows service can be called, and other applications can invoke its service by that name. The CanPauseAndContinue and CanStop attributes, as the name implies, allow pauses and resumes and allow stops.

To make a C # create Windows service program work, we need to create an entry point for it as you would a regular application. In the Windows service program, we also do this in the Main () function. First we create an instance of the Windows service in the Main () function, which should be an object of a subclass of the ServiceBase class, and then we call a Run () method defined by the base class ServiceBase class. However, the Run () method does not start C# to create the Windows service program, we must invoke the specific control function through the service control manager mentioned earlier to complete the startup of the Windows service program, that is, the service does not really start running until the object's OnStart () method is called. If you want to start multiple services at the same time in a Windows service program, then just define multiple instance objects of subclasses of the ServiceBae class in the Main () function, by creating an array object of the ServiceBase class, so that each object corresponds to a predefined service.

{System.ServiceProcess.ServiceBase [] MyServices; MyServices = new System.ServiceProcess.ServiceBase [] {new Service1 (), new Service2 ()}; System.ServiceProcess.ServiceBase.Run (MyServices);} static void Main () so far, I believe you have a deeper understanding of "how to create a Windows service program in C#". You might as well do it in practice! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
