软件手动更新代码(vs2003) 转载cnblogs

启动更新程序执行文件

private void button2_Click(object sender, System.EventArgs e)
        {
            string updateAppPath = Common.AppStartPath + @"\AutoUpdate.exe";
            if(!File.Exists(updateAppPath))
            {
                MessageBox.Show("无法找到AutoUpdate应用程序!");
                return;
            }
            string argments = Process.GetCurrentProcess().Id.ToString();
            ProcessStartInfo startInfo = new ProcessStartInfo(updateAppPath, argments);
            Process updateApp = new Process();
            updateApp.StartInfo = startInfo;
            updateApp.Start();
        }

得到启动程序的所在的文件夹路径

private static string strAppPath = String.Empty;

        /**//// <summary>
        /// 系统启动路径
        /// </summary>
        public static string AppStartPath
        {
            get
            {
                if (strAppPath == String.Empty)
                {
                    strAppPath =
                        System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
                    System.Uri uriPath = new Uri(strAppPath);
                    strAppPath = uriPath.LocalPath.Replace('/', '\\');

                }
                return strAppPath;
            }
        }
