. NET Development Windows Services Summary

Today I learned to create a Windows service under. NET and summarize your learning experience. Development environment: Visual Studio 20,121, authoring Program (1) Create an empty workaround (2) Add a console Application project (3) Add a Windows service as follows: (4) Right-click the code to see the following code:

 Public Windowsservice () {    InitializeComponent ();} protected Override void OnStart (string[] args) {            }protectedoverridevoid  OnStop ( ){            }

Where the OnStart method executes when the service is started, the OnStop method executes when the service is stopped, and two overloaded methods: OnPause, OnContinue, are executed when the service is paused, and when the service is resumed; they correspond to the actions shown:

　　

(5) Add code:

PrivateThread TimerThread;/// <summary>///Execute when service is started/// </summary>/// <param name= "args" ></param>protected Override voidOnStart (string[] args) {File.appendalltext ("D:\\1.txt", DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss") +": Windows service starts to work! \ r \ n", Encoding.default); TimerThread=NewThread (NewThreadStart (Start)); Timerthread.start ();}/// <summary>///Execute when service is stopped/// </summary>protected Override voidOnStop () {timerthread.abort (); File.appendalltext ("D:\\1.txt", DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss") +": Windows service finishes working! ", Encoding.default);}Private voidStart () { while(true)    {        using(StreamWriter writer =NewStreamWriter ("D:\\1.txt",true, Encoding.default)) {writer. WriteLine (DateTime.Now.ToString ("YYYY-MM-DD HH:mm:ss") +": Output every 10 seconds! "); } thread.sleep (Ten* +); }}

(6) Installation program, setting properties

To add a setup program in the designer

　　

A ProjectInstaller.cs file is generated, as shown in:

　　　　

Then you need to do two things:

① Setting the Account property of the ServiceProcessInstaller1 control to "LocalSystem"

② set the StartType property of the ServiceInstaller1 component to Automatic, set the service to start automatically

(7) Start-up service

Open vs Developer Command prompt tool run as Administrator

　　　　

Execute the command shown below:

　　　　

① go to the folder where the project is located and enter the \bin\debug\ path

② Install service command: InstallUtil ConsoleApplication.exe, then you can see the services we started in the list of services:

　　　　

The command to uninstall the service is: installutil/u ConsoleApplication.exe

After we modify the code, we need to unload the service before we can rebuild the success

③ Start Service

After starting the service, wait a moment to stop the service, then we open the 1.txt document under D, and we can see the results shown:

　　　　

Second, commissioning

In the state of the service running, we find the menu bar, debug-attach to Process

　　

Note Check the "Show All Users process" option, find our process, click Attach, and then add a breakpoint in the program, you can debug the program!
