C# 程序自動(dòng)升級(jí)的代碼,C#代碼片段分享,

悟靜 2014-04-26

展開全文

自動(dòng)更新的軟件的目的在于讓客戶不在為了尋找最新軟件花費(fèi)時(shí)間。也不用去到開發(fā)商的網(wǎng)站上查找。客戶端的軟件自動(dòng)會(huì)在程序啟動(dòng)前查找服務(wù)器上最新的版本。和自己當(dāng)前軟件的版本比較，如果服務(wù)器的是最新版本?？蛻舳藙t進(jìn)行自動(dòng)下載、解壓、安裝。當(dāng)然了下載是要有網(wǎng)絡(luò)的，并且用戶可以根據(jù)提示去完成操作。再也不用為找不到最新版本的軟件而頭疼。
轉(zhuǎn)自：http://blog.csdn.net/lybwwp/article/details/8426022

下面是我的大體思路，已經(jīng)得到了實(shí)現(xiàn)： 1、寫一個(gè)webservice，提供一個(gè)獲取服務(wù)器xml中版本的數(shù)據(jù)的方法。|

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

<Content>

  <Project id="程序名稱" Edition="1.0"> </Project>

</Content>

2、在WinForm應(yīng)用程序啟動(dòng)的時(shí)候，首先訪問webservice獲取服務(wù)器的xml中的版本號(hào)，然后獲取客戶端的xml中的版本號(hào)。將兩個(gè)版本號(hào)比較，若服務(wù)器中的版本號(hào)大，則提示提示可以在線更新應(yīng)用程序。

3、然后客戶端自動(dòng)下載網(wǎng)絡(luò)上的zip壓縮包到本機(jī)的指定位置，進(jìn)行自動(dòng)解壓縮到安裝的目錄進(jìn)行覆蓋。解壓縮完畢之后，用進(jìn)程打開所解壓過(guò)的exe文件進(jìn)行軟件安裝。同時(shí)關(guān)閉客戶端軟件所在的進(jìn)程。

4、注意：升級(jí)程序和應(yīng)用程序都是單獨(dú)的，應(yīng)用程序在使用時(shí)不能對(duì)本身進(jìn)行升級(jí)（覆蓋會(huì)失?。?br>
具體代碼如下：

第一部分應(yīng)用程序如口Program：

using System;

using System.Collections.Generic;

using System.Windows.Forms;

using Medicine_ERP;

using DevExpress.XtraEditors;

using System.Xml;

using Anshield_AutoFutures.BaseClase;

namespace Anshield_AutoFutures

{

    static class Program

    {

        private static void LoadMath()

        {

            //服務(wù)器上的版本號(hào)

            string NewEdition = "1.0";

            //應(yīng)用程序中的版本號(hào)

            string OldEdition = "1.0";

            try

            {

                //服務(wù)器上的版本號(hào)

                NewEdition = webserverClase.getCopyRightCode();

                //獲取系統(tǒng)中xml里面存儲(chǔ)的版本號(hào)               

                String fileName = Application.StartupPath + "\\XMLEdition.xml";

                XmlDocument xmlDoc = new XmlDocument();

                xmlDoc.Load(fileName);

                XmlNode xn = xmlDoc.SelectSingleNode("Content");

                XmlNodeList xnl = xn.ChildNodes;

                foreach (XmlNode xnf in xnl)

                {

                    XmlElement xe = (XmlElement)xnf;

                    if (xe.GetAttribute("id") == "jigou_plz")

                    {

                        OldEdition = xe.GetAttribute("Edition");//動(dòng)態(tài)數(shù)組

                    }

                    break;

                }

                double newE = double.Parse(NewEdition);

                double oldE = double.Parse(OldEdition);

                //比較兩個(gè)版本號(hào)，判斷應(yīng)用程序是否要更新

                if (newE > oldE)

                {

                    //更新程序¨

                    DialogResult dr = XtraMessageBox.Show("發(fā)現(xiàn)新的版本是否要更新該軟件", "平浪舟現(xiàn)貨程序化交易--更新提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);

                    if (dr == DialogResult.OK)

                    {

                        //打開下載窗口

                        // Application.Run(new DownUpdate());

                        //啟動(dòng)安裝程序                        

                        System.Diagnostics.Process.Start(Application.StartupPath + @"\Upgrade_Form.exe");

                        Application.Exit();

                    }

                    else

                    {

                        //若用戶取消，打開初始界面

                        anshield_Login login = new anshield_Login();

                        if (login.ShowDialog() == DialogResult.OK)

                        {

                            Application.Run(new Main_AutoFutures());

                        }

                    }

                }

                else

                {

                    //若服務(wù)器版本低于或相等客戶端，打開初始界面

                    anshield_Login login = new anshield_Login();

                    if (login.ShowDialog() == DialogResult.OK)

                    {

                        Application.Run(new Main_AutoFutures());

                    }

                }

            }

            catch

            {

                XtraMessageBox.Show("網(wǎng)絡(luò)鏈接失??！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);

            }

        }

        /// <summary>

        /// 應(yīng)用程序的主入口點(diǎn)。

        /// </summary>

        [STAThread]

        static void Main()

        {

            //保證同時(shí)只有一個(gè)客戶端在運(yùn)行   

            System.Threading.Mutex mutexMyapplication = new System.Threading.Mutex(false, "jigou_plz.exe");

            if (!mutexMyapplication.WaitOne(100, false))

            {

                XtraMessageBox.Show("程序" + Application.ProductName + "已經(jīng)在運(yùn)行！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);              

                return;

            }

            else

            {

                Application.EnableVisualStyles();

                Application.SetCompatibleTextRenderingDefault(false);

                //漢化

                hugengyong hu = new hugengyong();               

                DevExpress.UserSkins.OfficeSkins.Register();

                DevExpress.Skins.SkinManager.EnableFormSkins();

                DevExpress.UserSkins.BonusSkins.Register();

                LoadMath();

                }

        }

    }

}

            button2.Enabled = false;

            //自動(dòng)下載壓縮包,并且解壓，最后關(guān)閉當(dāng)前進(jìn)程，進(jìn)行安裝

            try

            {

                //下載自動(dòng)更新

                string downUrl = ConfigurationManager.ConnectionStrings["DownUrl"].ConnectionString.ToString().Trim();

                if (!string.IsNullOrEmpty(downUrl))

                {

                    DownloadFile(downUrl, zipFile, progressBar1, label1);

                }

                else

                {

                    MessageBox.Show("Config中的下載路徑配置錯(cuò)誤!", "錯(cuò)誤", MessageBoxButtons.OK, MessageBoxIcon.Error);

                    return;
