Initial knowledge of Windows services

1. Create a new Windows service

2. Switch to Code view and copy the following code into

The service creates a d:/1.txt file at 10S intervals

Using system;using system.collections.generic;using system.componentmodel;using system.data;using System.diagnostics;using system.io;using system.linq;using system.serviceprocess;using System.Text;using System.threading.tasks;using System.Timers; namespace windowsservicetest{public partial class Service1:servicebase{public Service1 () {InitializeComponent ();} protected override void OnStart (string[] args) {//Service Open Execution Code startdosomething ();} protected override void OnStop () {//service end execution code}protected override void OnPause () {//service suspend execution code base. OnPause ();} protected override void OnContinue () {//Service recovery execution code base. OnContinue ();} protected override void OnShutdown () {//system will close execution code base. OnShutdown ();} private void Startdosomething () {System.Timers.Timer timer = new System.Timers.Timer (10000);//interval 10 seconds timer. AutoReset = True;timer. Enabled = false; Executes the timer once. Elapsed + = new Elapsedeventhandler (writesomething); timer. Start ();} private void Writesomething (object source, System.Timers.ElapsedEventArgs e) {FileStream fs = Null;trY{fs = new FileStream ("D:/1.txt", FileMode.OpenOrCreate); string strText = @ "Creates the file repeatedly at 10-second intervals and remains unchanged if there is a file with the same name."// Get byte array byte[] data = new UTF8Encoding (). GetBytes (StrText);//start writing to FS. Write (data, 0, data. LENGTH);//clear buffer, close stream fs. Flush (); fs. Close (); fs. Dispose ();} CATCH{}FINALLY{IF (fs! = NULL) {fs. Close (); fs. Dispose ();}}}}

　　

3. Adding the installer and setting the control properties 1. Right-click on the design page and select Add Installer

2. Set the Account property of the first control in the upper-left corner to LocalService

3. You can modify the servicename of the second control (service name, non-existing conflict with the system), StartType set to Automatic

4. Compiling the project

1. Build the solution (CTRL+SHIFT+B) and generate the corresponding Xxx.exe when the compilation is complete

2. Find the installation directory of the InstallUtil inside the system such as C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe can't find it, use everything.

3.win+r CMD CD jump to InstallUtil installation path, run the following command installutil.exe+ space +4.1 generated EXE directory

CD C:\Windows\Microsoft.NET\Framework64\v4.0.30319

InstallUtil.exe E:\GitVSTest\WindowsServiceTest\WindowsServiceTest\bin\Debug\WindowsServiceTest.exe

5. Start the service In the computer-administration-services and applications-services, find the service you just compiled, right-click to start6. Modify the service 1. In the service, stop the corresponding service 2. Modify the source code and build the solution again (CTRL+SHIFT+B) 3. Start the service again7. Uninstall the service The name of the uninstall service run is similar to the 4.3 still in the InstallUtil directory, but the directory that runs installutil.exe/u generated EXE, for example: C:\Windows\Microsoft.NET\Framework64\ V4.0.30319>installutil.exe/u E:\GitVSTest\WindowsServiceT2\WindowsServiceT2\bin\Debug\WindowsServiceT2.exe
