如何实现winform客户端智能更新

1、在服务器上建立虚拟目录appUpdate 2、设置升级配置文件UpdateConfig.xml内容，放到虚拟目录appUpdate下： 格式：moduleName为动态链接库名称，vertion为当前版本号，appUrl为提供下载的地址 例子： <root> <module> <moduleName>Module1.dll</moduleName> <vertion>1.0.0.1</vertion> <appUrl>http://localhost/appUpdate/Module1.dll</appUrl> </module> <module> <moduleName>Module2.dll</moduleName> <vertion>1.0.0.1</vertion> <appUrl>http://localhost/appUpdate/Module2.dll</appUrl> </module> <module> <moduleName>ZiModule2ReportPrint.dll</moduleName> <vertion>1.0.0.1</vertion> <appUrl>http://localhost/appUpdate/ZiModule2ReportPrint.dll</appUrl> </module> </root> 3、WebService，部署到appUpdate虚拟目录下： [WebMethodAttribute] public System.Xml.XmlDocument AppUpdateVertion() { System.Xml.XmlDocument xml = new System.Xml.XmlDocument(); xml.Load(CurrentPath("/appUpdate") + @"/UpdateConfig.xml"); return xml; } private string CurrentPath(string virtualPath) { return HttpContext.Current.Server.MapPath(virtualPath); } 3、升级版本判断 /// <summary> ///从webServiceAddress中下载新版本 /// </summary> /// <param name="desPath">新版本的存放目录</param> /// <param name="webServiceAddress">webService的网址</param> private void VersionCheck(string desPath,string webServiceAddress) { try { #region 查看文件和目录 if(!desPath.EndsWith(@"/")) desPath += @"/"; if(!System.IO.Directory.Exists(desPath)) { System.IO.Directory.CreateDirectory(desPath); } string tempPath = desPath + @"tempDesPathCache/"; if(System.IO.Directory.Exists(tempPath)) { System.IO.Directory.Delete(tempPath,true); System.IO.Directory.CreateDirectory(tempPath); } else System.IO.Directory.CreateDirectory(tempPath); if(!System.IO.File.Exists(desPath + "UpdateConfig.xml")) { System.Xml.XmlDocument updateConfig = new System.Xml.XmlDocument(); updateConfig.LoadXml(@"<root></root>"); updateConfig.Save(desPath + "UpdateConfig.xml"); } #endregion AppUpdate.AppUpdate appUpdate = new Test.AppUpdate.AppUpdate(); appUpdate.Url = webServiceAddress; System.Xml.XmlDocument serverXmlDoc = appUpdate.AppUpdateVertion(); System.Xml.XmlDocument localXmlDoc = new System.Xml.XmlDocument(); localXmlDoc.Load(desPath + "UpdateConfig.xml"); bool newVersionExist = false; bool moduleExist = false; System.Xml.XmlNode serverNode0 = serverXmlDoc.ChildNodes[0]; System.Xml.XmlNode localNode0 = localXmlDoc.ChildNodes[0]; foreach(System.Xml.XmlNode serverNode in serverNode0) { moduleExist = false; foreach(System.Xml.XmlNode localNode in localNode0) { //找到对应模块 if(localNode.ChildNodes[0].InnerText == serverNode.ChildNodes[0].InnerText) { moduleExist = true; //版本号判断 if(localNode.ChildNodes[1].InnerText.CompareTo(serverNode.ChildNodes[1].InnerText) < 0) { newVersionExist = true; DownloadFile(serverNode.ChildNodes[2].InnerText,tempPath + serverNode.ChildNodes[0].InnerText); } break; } } //没找到对应模块 if(false == moduleExist) { DownloadFile(serverNode.ChildNodes[2].InnerText,tempPath + serverNode.ChildNodes[0].InnerText); } } //写入新UpdateConfig.xml升级完毕后替换 if(newVersionExist) { serverXmlDoc.Save(tempPath + "UpdateConfig.xml"); if(DialogResult.Yes == MessageBox.Show("有新版本，升级否","提示",MessageBoxButtons.YesNo)) { string[] dirs = System.IO.Directory.GetFiles(tempPath,"*.*"); string fileName; foreach (string dir in dirs) { fileName = ((dir.Split(Convert.ToChar(@"/")))[dir.Split(Convert.ToChar(@"/")).Length - 1]); if(System.IO.File.Exists(desPath + fileName)) { //TODO:可以支持备份以前版本 System.IO.File.Delete(desPath + fileName); } //TODO:如果系统正在运行，您得停止系统，至于如何停止，也许可以使用System.Diagnostics.Process System.IO.File.Move(dir,desPath + fileName); } MessageBox.Show("升级完毕"); } else { //TODO:可以支持重新提示升级 } } } catch(Exception ex) { throw new Exception("升级失败，原因是：" + ex.Message,ex); } } 4、下载文件： private void DownloadFile(string source,string fileName) { try { System.Net.WebClient myWebClient = new System.Net.WebClient(); myWebClient.DownloadFile(source,fileName); } catch(Exception ex) { throw new Exception("下载失败，原因是：" + ex.Message,ex); } } 5、客户端调用： string path =Application.StartupPath; VersionCheck(path,"http://localhost/AppUpdate/AppUpdate.asmx")
