C# 程序自動升級的代碼,C#代碼片段分享,

 悟靜 2014-04-26

自動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時間。也不用去到開發(fā)商的網(wǎng)站上查找?？蛻舳说能浖詣訒诔绦騿忧安檎曳?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進行自動下載、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)得到了實現(xiàn)： 1、  寫一個webservice，提供一個獲取服務(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)用程序啟動的時候，首先訪問webservice獲取服務(wù)器的xml中的版本號，然后獲取客戶端的xml中的版本號。將兩個版本號比較，若服務(wù)器中的版本號大，則提示提示可以在線更新應(yīng)用程序。

3、  然后客戶端自動下載網(wǎng)絡(luò)上的zip壓縮包到本機的指定位置，進行自動解壓縮到安裝的目錄進行覆蓋。解壓縮完畢之后，用進程打開所解壓過的exe文件進行軟件安裝。同時關(guān)閉客戶端軟件所在的進程。

4、注意：升級程序和應(yīng)用程序都是單獨的，應(yīng)用程序在使用時不能對本身進行升級（覆蓋會失?。?。

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
            string NewEdition = "1.0";
            //應(yīng)用程序中的版本號
            string OldEdition = "1.0";
 
            try
            {
                //服務(wù)器上的版本號
                NewEdition = webserverClase.getCopyRightCode();
 
                //獲取系統(tǒng)中xml里面存儲的版本號              
                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");//動態(tài)數(shù)組
                    }
                    break;
                }
                double newE = double.Parse(NewEdition);
                double oldE = double.Parse(OldEdition);
                //比較兩個版本號，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。
        /// </summary>
        [STAThread]
        static void Main()
        {
             
            //保證同時只有一個客戶端在運行  
            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)在運行！", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);             
                return;
            }
            else
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

        {
            string zipFile = path + @"\jigou_plz.zip";
            //關(guān)閉原有的應(yīng)用程序 
            killProess();
             
            btnDown.Enabled = false;
            button2.Enabled = false;
            //自動下載壓縮包,并且解壓，最后關(guān)閉當(dāng)前進程，進行安裝
            try
            {
                //下載自動更新
                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誤!", "錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    return;
                }
            }
            catch
            {
                MessageBox.Show("當(dāng)前沒有網(wǎng)絡(luò)或者文件地址不正確");
