基于C# 的自动程序更新的实现

最近在项目的时候不断的版本更新，客户很烦，偶亦很忙，于是就想添加个自动更新的东东在程序里，客户与我皆大欢喜：

废话少说了，先上代码：

 

首先修改解决方案名称\Properties\AssemblyInfo.cs文件中的版本信息

// 程序集的版本信息由下面四个值组成:
//
//      主版本
//      次版本
//      内部版本号
//      修订号
//
[assembly: AssemblyVersion("1.0.0.1")]
[assembly: AssemblyFileVersion("1.0.0.1")]

 

而后在数据库里添加一个当前版本的版本号，程序加载的时候去识别当前版本与数据库中的版本比较：

string currentVersion = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
            getOtherParam();
            string sql = "select versionID from versionmanager where create_dt=(select max(create_dt) from versionmanager) ";
            DataOperate dataOper = new DataOperate();
            DataTable table = dataOper.getDatatableExcuteSQL(sql);
            if (table.Rows.Count != 1)
            {
                MessageBox.Show("版本信息表出现异常，请核实");
                return;
            }
            string latestVersion = table.Rows[0]["VERSIONID"].ToString();
            if (currentVersion.Equals(latestVersion) == false)
            {
                DialogResult result = MessageBox.Show("有较新的版本可以下载,现在去下载吗？", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question);
                if (result == DialogResult.OK)
                {
                    string path = Application.StartupPath;
                    int i = path.IndexOf("bin", 0, StringComparison.InvariantCultureIgnoreCase);
                    string binPath = path.Substring(0, i) ;
                    Application.Exit();
                    Application.ExitThread();
                    System.Diagnostics.Process.Start(binPath + @"\UpdateProg.exe");                   
                }
                else
                {
                    Application.Run(new LoginForm());
                }
               
            }
            else
            {
                Application.Run(new LoginForm());
               
            }

 

更新exe文件的编写：

 

 private void UpdateForm_Load(object sender, EventArgs e)
        {           
            string path = Application.StartupPath;
            DeleteInDir(path + @"\bin");
            //modifyFilename(path +@"\bin");

            //下载并解压新文件
            string tempFolder = path;        //下载的目录
            bool isDownLoad = false;
            try
            {
                this.label1.Text = "开始下载更新程序……";
                FTPClient.DownLoad(tempFolder);  //下载
                this.label1.Text = "正在解压文件……";
                string s = FTPClient.unCompressRAR(tempFolder, tempFolder, "bin.rar"); //解压
                isDownLoad = true;
            }
            catch (Exception ex)
            {
                MessageBox.Show("从ftp下载文件失败，请关闭防火墙以及代理~" + ex.ToString());
                isDownLoad = false;
                Application.Exit();
            }

            if (isDownLoad == true)
            {
                Application.Exit();

                System.Diagnostics.Process.Start(path + @"\bin\release" + @"\江苏电信ODS网格管理.exe");
            }
        }

 

        private void DeleteInDir(string szDirPath)
        {
            if (szDirPath.Trim() == "" || !Directory.Exists(szDirPath))
                return;
            DirectoryInfo dirInfo = new DirectoryInfo(szDirPath);

            FileInfo[] fileInfos = dirInfo.GetFiles();
            if (fileInfos != null && fileInfos.Length > 0)
            {
                foreach (FileInfo fileInfo in fileInfos)
                {
                    //DateTime.Compare( fileInfo.LastWriteTime,DateTime.Now);
                    File.Delete(fileInfo.FullName); //删除文件
                }
            }

            DirectoryInfo[] dirInfos = dirInfo.GetDirectories();
            if (dirInfos != null && dirInfos.Length > 0)
            {
                foreach (DirectoryInfo childDirInfo in dirInfos)
                {
                    this.DeleteInDir(childDirInfo.FullName); //递归
                }
            }
            //Directory.Delete(dirInfo.FullName, true); //删除目录
        }
