winfrom更新

發(fā)布時(shí)間：2025/3/19 编程问答 19 豆豆

生活随笔收集整理的這篇文章主要介紹了 winfrom更新小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

原理：

工具生成更新配置節(jié)xml放到文件服務(wù)器上，外網(wǎng)可訪問；

能過本地配置文件與服務(wù)器配置文件日期屬性對比及配置節(jié)版本與大小屬性判斷有無更新；

存在更新，將文件從服務(wù)器下載到客戶端，并替換原程序重啟；

實(shí)現(xiàn)時(shí)，更新程序與原主程序是兩個(gè)不同的啟動程序，不存在文件占用，避免替換時(shí)文件被占用

如果做成一個(gè)程序，下載替換時(shí)需要通過外部批處理腳本關(guān)閉當(dāng)前應(yīng)用，并替換程序重啟應(yīng)用。在系統(tǒng)盤時(shí)要注意權(quán)限問題；

服務(wù)端生成xml代碼塊：

public partial class FormMain : Form{public FormMain(){InitializeComponent();txtWebUrl.Text = "localhost:8011";txtWebUrl.ForeColor = Color.Gray;}//獲取當(dāng)前目錄//string currentDirectory = AppDomain.CurrentDomain.BaseDirectory;string currentDirectory = System.Environment.CurrentDirectory;//服務(wù)端xml文件名稱string serverXmlName = "AutoupdateService.xml";//更新文件URL前綴string url = string.Empty;void CreateXml(){//創(chuàng)建文檔對象XmlDocument doc = new XmlDocument();//創(chuàng)建更新文件根節(jié)點(diǎn)XmlElement root = doc.CreateElement("Files");//設(shè)置更新節(jié)點(diǎn)日期root.SetAttribute("Date", DateTime.Now.ToString("yyyyMMdd"));////創(chuàng)建日期根節(jié)點(diǎn)//XmlElement versionDate = doc.CreateElement("UpDate");//versionDate.InnerText = DateTime.Now.ToString("yyyyMMdd");//doc.AppendChild(versionDate);//頭聲明XmlDeclaration xmldecl = doc.CreateXmlDeclaration("1.0", "utf-8", null);doc.AppendChild(xmldecl);DirectoryInfo dicInfo = new DirectoryInfo(currentDirectory);//調(diào)用遞歸方法組裝xml文件 PopuAllDirectory(doc, root, dicInfo);//追加節(jié)點(diǎn) doc.AppendChild(root);//保存文檔 doc.Save(serverXmlName);}//遞歸組裝xml文件方法private void PopuAllDirectory(XmlDocument doc, XmlElement root, DirectoryInfo dicInfo){foreach (FileInfo f in dicInfo.GetFiles()){//排除當(dāng)前目錄中生成服務(wù)端配置文件、此工具文件、后綴為pdb、config、ssk文件、包含vshost的文件List<string> notMimefile = new List<string>() { "pdb", "config", "ssk" };if (!f.Name.Contains("CreateXmlTools") && f.Name != "AutoupdateService.xml"&&f.Name != "AutoUpdater.exe" && !notMimefile.Contains(f.Name.Substring(f.Name.LastIndexOf(".") + 1)) && f.Name.IndexOf("vshost")==-1){string path = dicInfo.FullName.Replace(currentDirectory, "").Replace("\\", "/");string folderPath=string.Empty;if (path != string.Empty){folderPath = path.TrimStart('/') + "/";}XmlElement child = doc.CreateElement("File");child.SetAttribute("path", folderPath + f.Name);child.SetAttribute("url", url + path + "/" + f.Name);child.SetAttribute("version", FileVersionInfo.GetVersionInfo(f.FullName).FileVersion);child.SetAttribute("size", f.Length.ToString()); root.AppendChild(child);}}foreach (DirectoryInfo di in dicInfo.GetDirectories())PopuAllDirectory(doc, root, di);}private void btnCreate_Click(object sender, EventArgs e){string host = txtWebUrl.Text.Trim().TrimEnd('/').ToLower();url = (host.StartsWith("http") || host.StartsWith("https"))? host:"http://" + host;CreateXml();ReadXml();}private void ReadXml(){string path="AutoupdateService.xml";rtbXml.ReadOnly = true;if (File.Exists(path)){rtbXml.Text = File.ReadAllText(path);}}private void txtWebUrl_Enter(object sender, EventArgs e){txtWebUrl.ForeColor = Color.Black;if (txtWebUrl.Text.Trim() == "localhost:8011"){txtWebUrl.Text = string.Empty;}}}

winform更新解決辦法：

思路一：

生成一個(gè)批處理文件
執(zhí)行批處理文件并且自身退出
批處理文件中執(zhí)行覆蓋操作
批處理中最后一句啟動本程序
完成更新

思路二：

主程序A更新自動更新程序B，自動更新程序B更新主程序A

C# Timer用法及實(shí)例詳解 ?http://developer.51cto.com/art/200909/149829.htm

System.Timers.Timer t = new System.Timers.Timer(10000); //實(shí)例化Timer類，設(shè)置間隔時(shí)間為10000毫秒； t.Elapsed += new System.Timers.ElapsedEventHandler(theout); //到達(dá)時(shí)間的時(shí)候執(zhí)行事件； t.AutoReset = true; //設(shè)置是執(zhí)行一次（false）還是一直執(zhí)行(true)； t.Enabled = true; //是否執(zhí)行System.Timers.Timer.Elapsed事件； public void theout( object source, System.Timers.ElapsedEventArgs e) { MessageBox.Show("OK!"); }

Timer timer1 = new Timer();timer1.Interval = 1000;timer1.Enabled = true;timer1.Tick += new EventHandler(timer1EventProcessor);//添加事件

關(guān)于退出程序

this.Close();???只是關(guān)閉當(dāng)前窗口，若不是主窗體的話，是無法退出程序的，另外若有托管線程（非主線程），也無法干凈地退出；?

Application.Exit(); 方法停止在所有線程上運(yùn)行的所有消息循環(huán)，并關(guān)閉應(yīng)用程序的所有窗口

強(qiáng)制直接退出了整個(gè)程序，不只是關(guān)閉子窗體：

Process.GetCurrentProcess().Kill(); ? ??//終止當(dāng)前正在運(yùn)行的線程

或者System.Threading.Thread.CurrentThread.Abort();

或者Application.ExitThread();

System.Environment.Exit(0);???這是最徹底的退出方式，不管什么線程都被強(qiáng)制退出，把程序結(jié)束的很干凈。?
