C#实现Winform程序自动进行版本升级更新

一.首先新建一个Wnform主程序TestMainProgarm，界面如下：

通过AssemblyInfo.cs文件查看程序版本：

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

string ver = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();可以获取版本号；
我们可以在主程序运行前检查运行程序的版本和服务器上的版本是否一致，还是版本比较低；主程序代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using Update;namespace TestMainProgarm
{static class Program{/// <summary>/// 应用程序的主入口点。/// </summary>[STAThread]static void Main(){if (checkUpdateLoad()){Application.Exit();return;}Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new FrmMain());}public static bool checkUpdateLoad(){bool result = false;SoftUpdate app = new SoftUpdate(Application.ExecutablePath, "TestMainProgarm");try{if (app.IsUpdate && MessageBox.Show("检查到新版本，是否更新？", "版本检查", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes){string path = Application.StartupPath.Replace("program", "");System.Diagnostics.Process process = new System.Diagnostics.Process();process.StartInfo.FileName = "autoUpdate.exe";process.StartInfo.WorkingDirectory = path;//要掉用得exe路径例如:"C:\windows";               process.StartInfo.CreateNoWindow = true;process.Start();result = true;}else{result = false;}}catch (Exception ex){MessageBox.Show(ex.Message);result = false;}return result;}}
}

二.自动升级的程序：

代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Update;namespace autoUpdate
{public partial class Form1 : Form{[DllImport("zipfile.dll")]public static extern int MyZip_ExtractFileAll(string zipfile, string pathname);public Form1(){InitializeComponent();//清除之前下载来的rar文件if (File.Exists(Application.StartupPath + "\\Update_autoUpdate.zip")){try{File.Delete(Application.StartupPath + "\\Update_autoUpdate.zip");}catch (Exception){}}if (Directory.Exists(Application.StartupPath + "\\autoupload")){try{Directory.Delete(Application.StartupPath + "\\autoupload", true);}catch (Exception){}}//检查服务端是否有新版本程序checkUpdate();timer1.Enabled = true;}SoftUpdate app = new SoftUpdate(Application.ExecutablePath, "TestMainProgarm");public void checkUpdate(){app.UpdateFinish += new UpdateState(app_UpdateFinish);try{if (app.IsUpdate){app.Update();}else{MessageBox.Show("未检测到新版本!");Application.Exit();}}catch (Exception ex){MessageBox.Show(ex.Message);}}void app_UpdateFinish(){//解压下载后的文件string path = app.FinalZipName;if (File.Exists(path)){//后改的 先解压滤波zip植入ini然后再重新压缩string dirEcgPath = Application.StartupPath + "\\" + "autoupload";if (!Directory.Exists(dirEcgPath)){Directory.CreateDirectory(dirEcgPath);}//开始解压压缩包MyZip_ExtractFileAll(path, dirEcgPath);try{//复制新文件替换旧文件DirectoryInfo TheFolder = new DirectoryInfo(dirEcgPath);foreach (FileInfo NextFile in TheFolder.GetFiles()){File.Copy(NextFile.FullName, Application.StartupPath + "\\program\\" + NextFile.Name, true);}Directory.Delete(dirEcgPath, true);File.Delete(path);//覆盖完成 重新启动程序path = Application.StartupPath + "\\program";System.Diagnostics.Process process = new System.Diagnostics.Process();process.StartInfo.FileName = "TestMainProgarm.exe";process.StartInfo.WorkingDirectory = path;//要掉用得exe路径例如:"C:\windows";               process.StartInfo.CreateNoWindow = true;process.Start();Application.Exit();}catch (Exception){MessageBox.Show("请关闭系统在执行更新操作!");Application.Exit();}}}private void timer1_Tick(object sender, EventArgs e){label2.Text = "下载文件进度:" + COMMON.CommonMethod.autostep.ToString() + "%";this.progressBar1.Value = COMMON.CommonMethod.autostep;if (COMMON.CommonMethod.autostep == 100){timer1.Enabled = false;}}}
}

三.先在服务器上放置一个存放软件版本号和最新版程序路径的xml文件，目前网站上的程序时1.0.0.3版本，我是在本机IIS上新建了一个网站进行测试的，网站路径为：http://192.168.1.63:8050/update.xml，xml文件内容如下：

<?xml version="1.0" encoding="utf-8" ?>
<Update><Soft Name="TestMainProgarm"><Verson>1.0.0.3</Verson><DownLoad>http://192.168.1.63:8050/Update_autoUpdate.zip</DownLoad></Soft>
</Update>

网站中的文件如下：
