• winform程序更新


    1. 更新程序和主程序是分开的,得在做一个exe可执行更新程序。
    2. 主程序在登陆时判断是否需要更新。

        我这边判断方式是直接在配置文件里面设置版本号,然后和服务器上面的版本对比,低于服务器版本就更新程序。

       
    //该文件配置在app.config里面
      <!-- 发布前修改版本号 -->

    <?xml version="1.0" encoding="utf-8"?>
    <configuration>

      <appSettings>

       <add key="version" value="1.1.6" />

    </appSettings>
    </configuration>

      获取配置文件信息,前几章随笔里面有提到。

      

              Version now_v = new Version(strval);//当前版本
                    Version load_v = new Version(model.version.ToString());//历史版本
                    if (now_v < load_v && MessageBox.Show("检查到新版本,是否更新?", "Update", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
                    {   
                        //更新(调用更新的exe)返回新版本路径
                        string fileName = Application.StartupPath + @"ClientUpdate.exe";
                        Process p = new Process();
                        p.StartInfo.UseShellExecute = false;
                        p.StartInfo.RedirectStandardOutput = true;
                        p.StartInfo.FileName = fileName;
                        p.StartInfo.CreateNoWindow = true;
                        p.StartInfo.Arguments = now_v + " " + load_v + " " + cn.showVersion()+" "+ model.download.ToString();//参数以空格分隔,如果某个参数为空,可以传入””
                        p.Start();
                        System.Environment.Exit(System.Environment.ExitCode);   //结束主线程
                    }
    

      3.接下来是更新程序的代码部分

        

            private void Form1_Load(object sender, EventArgs e)
            {
                try
                {
                    String[] CmdArgs = System.Environment.GetCommandLineArgs();
                    if (CmdArgs.Length > 1)
                    {
                        
                        //参数0是它本身的路径
                        String arg0 = CmdArgs[0].ToString();//程序路径
                        String arg1 = CmdArgs[1].ToString();//旧版本号
                        String arg2 = CmdArgs[2].ToString();//新版本号
                        String arg3 = CmdArgs[3].ToString();//更新版本
                        String arg4 = CmdArgs[4].ToString();//版本地址
    
                        //更新
                        lab_version.Text = arg2;
    
                        this.Text = arg3 + "更新";
                        UpdateDownLoad(arg4);//
    
                        listBox1.Items.Add("更新信息");
                        foreach (var item in CmdArgs)
                        {
                            listBox1.Items.Add(item.ToString());
                        }
    
                        label6.Text = "完成更新";
                        button1.Visible = true;
    
    
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
               
            }
    
     /// <summary>
            /// 更新
            /// </summary>
            /// <param name="verStr"></param>
            private void UpdateDownLoad(string verStr)
            {
                WebClient wc = new WebClient();
                wc.DownloadProgressChanged += wc_DownloadProgressChanged;
                wc.DownloadFileAsync(new Uri(verStr), "../"+ZipHelper.zipFileFullName);//要下载文件的路径,下载之后的命名
            }
    
            void wc_DownloadProgressChanged(object sender, System.Net.DownloadProgressChangedEventArgs e)
            {
                Action act = () =>
                {
                    this.progressBar1.Value = e.ProgressPercentage;
                    this.label1.Text = e.ProgressPercentage + "%";
    
                };
                this.Invoke(act);
    
                if (e.ProgressPercentage == 100)
                {
                    //下载完成之后开始覆盖
    
                    ZipHelper.Unzip();//调用解压的类
    
                    this.button1.Enabled = true;
    
                }
            }
    
            public delegate void ChangeBarDel(System.Net.DownloadProgressChangedEventArgs e);
    
            /// <summary>
            /// 完成更新之后再次打开主程序
            /// </summary>
            /// <param name="sender"></param>
            /// <param name="e"></param>
            private void button1_Click(object sender, EventArgs e)
            {
                this.Close();
                string fileName = Application.StartupPath + @"GoldenTax.exe";
                Process p = new Process();
                p.StartInfo.UseShellExecute = false;
                p.StartInfo.RedirectStandardOutput = true;
                p.StartInfo.FileName = fileName;
                p.StartInfo.CreateNoWindow = true;
                p.Start();
                System.Environment.Exit(System.Environment.ExitCode);   //结束主线程
            }
        }
    

      4.解压类

    class ZipHelper
        {
    
            public static string zipFileFullName = "Update.rar";
            public static void Unzip()
            {
                try
                {
                    string _appPath = new DirectoryInfo(Assembly.GetExecutingAssembly().ManifestModule.FullyQualifiedName).Parent.FullName;
    
                    string s7z = _appPath + @"7-Zip7z.exe";
                    System.Diagnostics.Process pNew = new System.Diagnostics.Process();
                    pNew.StartInfo.FileName = s7z;
                    pNew.StartInfo.Arguments = string.Format(" x "{0}\{1}" -y -o"{0}"", _appPath + "/../", zipFileFullName);
                    //x "1" -y -o"2" 这段7z命令的意思: x是解压的意思 "{0}"的位置写要解压文件路径"{1}"这个1的位置写要解压的文件名 -y是覆盖的意思 -o是要解压的位置
                    pNew.Start();
                    //等待完成
                    pNew.WaitForExit();
                    //删除压缩包
                    File.Delete(_appPath + @"/../" + zipFileFullName);
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
                
            }
    
        }
