The principle of automatic upgrade:

(1) After the client is logged in, determine the version number in the local configuration file and the server version number, if it is smaller than the server version number, close this program, start the upgrade program

  //Start the upgrade program        Private voidAppupdate () {
Contact Server Request Server version number Upgradeconfig UPGRADECONIFG= appoutter.tcpconn.sendreceiveobject<string, Upgradeconfig> ("getupmsg","resupmsg", the,"Test");
If the server has a large version number, start the upgrade programif(Upgradeconifg.appversion >getmenuversion ()) {
To get the name of the upgrade program from the configuration file, start the programstringUpgradeapppath = system.configuration.configurationmanager.appsettings["Upgradeapp"]; stringCallBack = AppDomain.CurrentDomain.BaseDirectory +Upgradeapppath; if(File.exists (callBack)) {if(Properties.Settings.Default.IpAddress = = system.configuration.configurationmanager.appsettings["IPAddress"]) {System.Diagnostics.Process Process=System.Diagnostics.Process.Start (CallBack); }                    Else{System.Diagnostics.Process Process= System.Diagnostics.Process.Start (CallBack,"s"); }                }                Else{MessageBox.Show ("Target program does not exist"+callBack); } System.Environment.Exit (0); }        }

Configuration file for the upgrade program:

Exeappname is the main program name that is configured to restart the main program after the upgrade is completed and after you close itself.

Part of the code:

   Private voidstartupdate () {//Set get file information class priority HighUpgradeconfig UPGRADECONIFG = connection. sendreceiveobject<string, Upgradeconfig> ("getupmsg","resupmsg", the,"Test", Customoptions, customoptions); if(Upgradeconifg.appversion >0) {Listbox1.datasource=upgradeconifg.filelist; TextBox1.Text=upgradeConifg.AppVersion.ToString (); //The number of files that need to be downloadedUpfilescount =UpgradeConifg.FileList.Count; //Send message request download upgrade file                stringFilePath =AppDomain.CurrentDomain.BaseDirectory; //sends the local file's storage path to the server side (which is then brought back by the server-side Sendinfo)Connection. sendobject<string> ("Getupfile", FilePath, customoptions); }            Else{MessageBox.Show ("No upgrade required"); }        }

After getting the list of files for this upgrade from the server, download the files from the server to local.

After the upgrade is complete, close the program, start the main program, complete the upgrade.
