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：

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 currBytes = 0;//当前下载流量

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

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;
}
}
