c# winform 自动升级

winform自动升级程序示例源码下载 

客户端思路：

1、新建一个配置文件Update.ini，用来存放软件的客户端版本：

[update] version=2011-09-09 15:26

2、新建一个单独的客户端升级程序Update.exe：

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Net;

using System.Threading;

using System.IO;

publicpartialclassFrmUpdate : Form

{

//关闭进度条的委托

publicdelegatevoidCloseProgressDelegate();

//声明关闭进度条事件

publiceventCloseProgressDelegate CloseProgress;

UpdateService.Service service = null;//webservice服务

WebClient wc = null;

string url;//获取下载地址

string[] zips;//获取升级压缩包

int zipsIndex = 0;//当前正在下载的zips下标

long preBytes = 0;//上一次下载流量

long currBytes = 0;//当前下载流量

public FrmUpdate()

{

InitializeComponent();

service = new UpdateService.Service();//webservice服务

url = service.GetUrl();//获取下载地址

zips = service.GetZips();//获取升级压缩包

}

privatevoid FrmUpdate_Load(object sender, EventArgs e)

{

try

{

//用子线程工作

Thread t = newThread(newThreadStart(DownLoad));

t.IsBackground = true;//设为后台线程

t.Start();

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

}

/// <summary>

/// </summary>

privatevoid DownLoad()

{

try

{

CloseProgress += newCloseProgressDelegate(FrmUpdate_CloseProgress);

if (zips.Length > 0)

{

wc = newWebClient();

wc.DownloadProgressChanged += newDownloadProgressChangedEventHandler(wc_DownloadProgressChanged);

wc.DownloadFileCompleted += newAsyncCompletedEventHandler(wc_DownloadFileCompleted);

wc.DownloadFileAsync(newUri(url + zips[zipsIndex]), zips[zipsIndex]);

}

else

{

FrmUpdate_CloseProgress();//调用关闭进度条事件

}

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

}

/// <summary>

/// </summary>

void wc_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)

{

zipsIndex++;

if (zipsIndex < zips.Length)

{

//继续下载下一个压缩包

wc = newWebClient();

wc.DownloadProgressChanged += newDownloadProgressChangedEventHandler(wc_DownloadProgressChanged);

wc.DownloadFileCompleted += newAsyncCompletedEventHandler(wc_DownloadFileCompleted);

wc.DownloadFileAsync(newUri(url + zips[zipsIndex]), zips[zipsIndex]);

}

else

{

//解压

int maximum = ZipClass.GetMaximum(zips);

foreach (string zip in zips)

{

ZipClass.UnZip(Application.StartupPath + @"\" + zip, "", maximum, FrmUpdate_SetProgress);

File.Delete(Application.StartupPath + @"\" + zip);

}

FrmUpdate_CloseProgress();//调用关闭进度条事件

}

}

/// <summary>

/// 下载时触发

void wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)

{

if (this.InvokeRequired)

{

this.Invoke(newDownloadProgressChangedEventHandler(wc_DownloadProgressChanged), newobject[] { sender, e });

}

else

{

label1.Text = "正在下载自解压包" + zips[zipsIndex] + "(" + (zipsIndex + 1).ToString() + "/" + zips.Length + ")";

progressBar1.Maximum = 100;

progressBar1.Value = e.ProgressPercentage;

currBytes = e.BytesReceived;//当前下载流量

}

}

/// <summary>

zipsIndex++;

{

wc.Dispose();

}

if (zips.Length > 0)

{

MessageBox.Show("升级成功！");

}

else

{

MessageBox.Show("未找到升级包！");

}

IniClass ini = new IniClass(Application.StartupPath + @"\Update.ini");

string serviceVersion = service.GetVersion();//服务端版本

ini.IniWriteValue("update", "version", serviceVersion);//更新成功后将版本写入配置文件

Application.Exit();//退出升级程序

Process.Start("Main.exe");//打开主程序Main.exe

}

}

//1秒计算一次速度

privatevoid timer1_Tick(object sender, EventArgs e)

{

this.Text = ((currBytes - preBytes) / 1024).ToString() + "kb/s";//速度

preBytes = currBytes;//上一次下载流量

}

}

}

解压类ZipClass.cs：引用 ICSharpCode.SharpZipLib.dll

publicstaticbool UnZip(string zipFilePath, string unZipDir, int maximum, SetProgressDelegate setProgressDelegate)

{

if (zipFilePath == string.Empty)

{

thrownew System.IO.FileNotFoundException("压缩文件不不能为空！");

}

if (!File.Exists(zipFilePath))

{

thrownew System.IO.FileNotFoundException("压缩文件: " + zipFilePath + " 不存在!");

}

//解压文件夹为空时默认与压缩文件同一级目录下，跟压缩文件同名的文件夹

if (unZipDir == string.Empty)

unZipDir = zipFilePath.Replace(Path.GetFileName(zipFilePath), "");

unZipDir += "//";

if (!Directory.Exists(unZipDir))

Directory.CreateDirectory(unZipDir);

try

{

using (ZipInputStream s = newZipInputStream(File.OpenRead(zipFilePath)))

{

ZipEntry theEntry;

while ((theEntry = s.GetNextEntry()) != null)

{

string directoryName = Path.GetDirectoryName(theEntry.Name);

string fileName = Path.GetFileName(theEntry.Name);

if (directoryName.Length > 0)

{

Directory.CreateDirectory(unZipDir + directoryName);

}

if (!directoryName.EndsWith("//"))

directoryName += "//";

if (fileName != String.Empty)

{

using (FileStream streamWriter = File.Create(unZipDir + theEntry.Name))

{

int size = 2048;

byte[] data = newbyte[2048];

while (true)

{

publicstaticint GetMaximum(string[] zips)

{

foreach (string zip in zips)

{

3、将update.ini和Update.exe复制到主程序目录，主程序登录时判断客户端版本是否与服务端版本相同，如不同，则做升级：

IniClass ini = newIniClass(Application.StartupPath + @"\Update.ini");

UpdateService.Service service = new UpdateService.Service();

string clientVersion = ini.IniReadValue("update", "version");//客户端版本

string serviceVersion = service.GetVersion();//服务端版本

if (clientVersion != serviceVersion)

{

DialogResult dialogResult = MessageBox.Show("有新版本，是否更新？", "升级", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);

if (dialogResult == DialogResult.OK)

{

Application.Exit();

Process.Start("Update.exe");

}

}

else

{

MessageBox.Show("已更新至最高版本！");

}

服务端思路：

1、新建一个Web Service，在Web.Config中配置：

<connectionStrings>

<!--版本号-->

<add name="version" connectionString="2011-09-20 15:17"/>

<!--下载地址-->

<add name="url" connectionString ="http://localhost:8546/WebSite/"/>

<!--下载目录，最好为一级目录免得麻烦-->

<add name="directory" connectionString ="UpdateFile"/>

</connectionStrings>

2、在Service.cs写入以下代码：

using System;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.IO;

using System.Configuration;

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

publicclassService : System.Web.Services.WebService

{

public Service()

{

//如果使用设计的组件，请取消注释以下行

//InitializeComponent();

}

/// <summary>

/// 获取版本号

/// </summary>

/// <returns>更新版本号</returns>

[WebMethod]

publicstring GetVersion()

{

returnConfigurationManager.ConnectionStrings["version"].ConnectionString;

}

/// <summary>

/// 获取下载地址

/// </summary>

/// <returns>下载地址</returns>

[WebMethod]

publicstring GetUrl()

{

returnConfigurationManager.ConnectionStrings["url"].ConnectionString + ConfigurationManager.ConnectionStrings["directory"].ConnectionString + "/";

}

/// <summary>

/// 获取下载zip压缩包

/// </summary>

/// <returns>下载zip压缩包</returns>

[WebMethod]

publicstring[] GetZips()

{

string folder = HttpRuntime.AppDomainAppPath + ConfigurationManager.ConnectionStrings["directory"].ConnectionString;

string[] zips = Directory.GetFileSystemEntries(folder);

for (int i = 0; i < zips.Length; i++)

{

zips[i] = Path.GetFileName(zips[i]);

}

return zips;

}

}
