上篇文章主要介绍了webservice的部署以及主要的代码，下面给大家贴上主程序的代码，并简单的讲解。主程序判断是否有更新时通过主程序目录下有一个update.ini文件内的version是否有变化，主要思路为判断客户端的version是否==服务器端webservice提取到的version的值，update.ini文件内容如下：

[update]
version=20132103 //通过这个客户端的version于服务器端的version相比较，如果不等于则为更新
program=BJCreation.CallAppWindow.Windows.exe //主程序的目录，也就是谁要启动这个update.exe[webservice]
url=http://localhost:1546/UpdateWeb/sxsUpdateWebService.asmx //这个就是webservice的地址
method=GetUpdateInfos //webservice的方法名

1、变量定义

//关闭进度条的委托public delegate void CloseProgressDelegate();public delegate void OnGoToShowLogDegate();public delegate void OnGoTOShowRtbLogDelate(object message);//声明关闭进度条事件public event CloseProgressDelegate CloseProgress;string serviceVersion;WebClient wc = null;IniClass ini; //ini文件的操作string url;//获取下载地址 string[] zips;//获取升级压缩包string zip = "";//当前正在下载的压缩包string uploadLog = string.Empty; //更新日志int zipsIndex = 0;//当前正在下载的zips下标long preBytes = 0;//上一次下载流量long currBytes = 0;//当前下载流量private static int time = 3;//3秒自动退出，没有更新的话自动退出string filePath = string.Empty; 

2、构造函数

public FormUpdate(){InitializeComponent();this.btnDownload.Enabled = false;ini = new IniClass(Application.StartupPath + @"\Update.ini");Thread thread = new Thread(new ThreadStart(ThreadMethod));thread.Start();}/// <summary>/// 如果将更新程序放到根目录下面的子目录内，如Realeas/Update/update.exe，则启动时需要传递参数调用这个方法/// 主程序的调用方式如下：process.start("update/update.exe","\""+Application.StartupPath+"\"");因为如果当前目录含有空格类似c:\programes files\程序1 这样的目录，用start方式启动不成功，必须要将start的参数2改为短文件名 或者直接加""的方式 /// 构造窗体/// </summary>/// <param name="path"></param>public FormUpdate( string path ){this.filePath = path;InitializeComponent();this.btnDownload.Enabled = false;ini = new IniClass( Application.StartupPath + @"\Update.ini" );Thread thread = new Thread( new ThreadStart( ThreadMethod ) );thread.Start();}

//通过多线程去处理webservice的读取，防止界面卡死。webservice调用使用了代理的方式，不用添加web引用WebServiceHelper是一个类，实现了webservice的调用。只需要将webservice地址和方法名传递过去即可实现。

        void ThreadMethod(){try{string webServiceUrl = ini.IniReadValue("webservice", "url");//wsdl地址  string method = ini.IniReadValue("webservice", "method");//string[] strArray = (string[])WebServiceHelper.InvokeWebService(webServiceUrl, method, null);//调用webservice并返回结果uploadLog = strArray[3];zips = strArray[2].Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);url = strArray[1];string clentVersion = ini.IniReadValue("update", "version");serviceVersion = strArray[0];//服务端版本if (!string.Equals(clentVersion, serviceVersion)){//如果不等则直接显示更新日志及更新列表OnGoToShowLogDegate logHandler = new OnGoToShowLogDegate(ShowLog);this.Invoke(logHandler);}else{OnGoToShowLogDegate logHandler = new OnGoToShowLogDegate(ShowRtbLogView);this.Invoke(logHandler);}}catch (Exception ex){OnGoTOShowRtbLogDelate logHandler = new OnGoTOShowRtbLogDelate(ShowRtbLog);this.Invoke(logHandler, new object[] { ex.Message });}}

更新程序首页日志的展示

void ShowLog(){this.groupBox1.Text = serviceVersion + "更新日志";this.rtbUpdateLog.Text = string.IsNullOrEmpty(uploadLog) ? "暂时无更新" : uploadLog;if (zips.Length > 0){foreach (string item in zips){string size = "";try{HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(new Uri(url + item));HttpWebResponse myRes = (HttpWebResponse)myReq.GetResponse();size = GetFileSize(myRes.ContentLength);myRes.Close();}catch (Exception){//如果有异常则不处理}ListViewItem lsv = new ListViewItem();lsv.Text = item;lsv.SubItems.Add(size);this.lsvFiles.Items.Add(lsv);}this.btnDownload.Enabled = true;}}private string GetFileSize(long size){string msg = "0B";if (size == 0){}else if (size > 0 && size < 1024){msg = size + "B";}else if (size > 1024 && size < 1024 * 1024){msg = (size / 1024) + "KB";}else if (size > 1024 * 1024 && size < 1024 * 1024 * 1024){msg = size / (1024 * 1024) + "MB";}return msg;}

下面的是下载和解压的步骤

/// <summary>/// 下载更新/// </summary>private void DownLoad(){try{CloseProgress += new CloseProgressDelegate(FrmUpdate_CloseProgress);if (zips.Length > 0){wc = new WebClient();wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged);wc.DownloadFileCompleted += new AsyncCompletedEventHandler(wc_DownloadFileCompleted);wc.DownloadFileAsync(new Uri(url + zips[zipsIndex]), zips[zipsIndex]);}else{FrmUpdate_CloseProgress();//调用关闭进度条事件}}catch (Exception ex){MessageBox.Show(ex.Message);}}/// <summary>/// 下载完成后触发/// </summary>void wc_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e){try{if (zipsIndex < zips.Length){//继续下载下一个压缩包wc = new WebClient();wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged);wc.DownloadFileCompleted += new AsyncCompletedEventHandler(wc_DownloadFileCompleted);string url2 = url + zips[zipsIndex];wc.DownloadFileAsync(new Uri(url2), zips[zipsIndex]);}else{//解压string _path = string.IsNullOrEmpty(filePath) ? Application.StartupPath : filePath;int maximum = ZipClass.GetMaximum(zips, _path);foreach (string zip in zips){string fileName = _path + @"\" + zip;string extension = Path.GetExtension(fileName);if (extension != ".zip"){//如果不是zip的文件则不允许解压。continue;}ZipClass.UnZip(_path + @"\" + zip, "", maximum, FrmUpdate_SetProgress);File.Delete(_path + @"\" + zip);}FrmUpdate_CloseProgress();//调用关闭进度条事件}//此行放置在此处zipsIndex++;}catch (Exception ex){Log.LogToFile(ex.Message);}}/// <summary>/// 下载时触发/// </summary>void wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e){if (this.InvokeRequired){this.Invoke(new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged), new object[] { sender, e });}else{try{lblMessage.Text = "正在下载自解压包  " + zips[zipsIndex] + "(" + (zipsIndex + 1).ToString() + "/" + zips.Length + ")";progressBar1.Maximum = 100;progressBar1.Value = e.ProgressPercentage;currBytes = e.BytesReceived;//当前下载流量}catch (Exception){//如果出错，直接运行。}}}/// <summary>/// 解压时进度条事件/// </summary>/// <param name="maximum">进度条最大值</param>private void FrmUpdate_SetProgress(int maximum, string msg){if (this.InvokeRequired){this.Invoke(new ZipClass.SetProgressDelegate(FrmUpdate_SetProgress), new object[] { maximum, msg });}else{timer1.Enabled = false;//this.Text = "升级";if (zipsIndex == zips.Length){//刚压缩完progressBar1.Value = 0;zipsIndex++;}lblMessage.Text = "正在解压" + msg + "(" + (progressBar1.Value + 1).ToString() + "/" + maximum + ")";progressBar1.Maximum = maximum;progressBar1.Value++;}}

网上客户端升级源码下载 ----该程序是由网上的程序修改而来，大家有兴趣可以看看
UpdateWeb的源码下载(需要的可以研究一下,Bin下面有打包好的real)

更新主程序下载(此程序只包含有windows程序，如果报错自行引用Bin目录下面的dll即可。)

如果需要对Update.exe程序进行调用则直接书写

                    Process _process = new Process();_process.StartInfo.FileName = "Update/BJCreation.AutoUpdate.Windows.exe";_process.StartInfo.Arguments="\""+ Application.StartupPath+"\"";_process.StartInfo.WorkingDirectory =Application.StartupPath;_process.Start();

如果将Update.exe放在根目录下，则直接

Process.Start("Update.exe");即可
