五、AutoUpdaterTest

5.1、实体类

作用:本地配置AutoUpdateConfig.xml文件的序列化及反序列化实体对象。

AutoUpdateConfig.cs

5.2、通用类

作用:应用程序全局静态常量。全局参数都在此设置,方便统一管理。注:客户端是否检测更新,也是在此设置默认值。

AppContext.cs

作用:应用程序配置。

    public class AppConfig     {         private static readonly object _lock = new object();         private static AppConfig _instance = null;          #region 自动更新配置         /// <summary>         /// 自动更新配置数据         /// </summary>         public AutoUpdateConfig AutoUpdateConfigData { get; set; }          private AppConfig()         {             AutoUpdateConfigData = new AutoUpdateConfig();         }          public static AppConfig Instance         {             get             {                 if (_instance == null)                 {                     lock (_lock)                     {                         if (_instance == null)                         {                             _instance = new AppConfig();                         }                     }                 }                 return _instance;             }         }          /// <summary>         /// 本地自动更新下载临时文件夹路径         /// </summary>         public string TempPath         {             get             {                 return string.Format("{0}\{1}", Application.StartupPath, GlobalParam.TempDir);             }         }          /// <summary>         /// 初始化系统配置信息         /// </summary>         public void InitialSystemConfig()         {             AutoUpdateConfigData.AutoUpdateMode = AppContext.AutoUpdateConfigData.AutoUpdateMode;             AutoUpdateConfigData.AutoUpdateHttpUrl = AppContext.AutoUpdateConfigData.AutoUpdateHttpUrl;         }         #endregion     }

AppConfig.cs

5.3、本地配置文件

作用:配置自动更新模式及相关。

注1:复制到输出目录选择始终复制。

注2:主程序运行时,先读取此配置更新文件,然后给AppContext上下文赋值,接着给AppConfig配置赋值。

C# WinForm通用自动更新器C# WinForm通用自动更新器

<?xml version="1.0" encoding="utf-8" ?> <AutoUpdateConfig>   <!--自动升级模式:当前仅支持HTTP-->   <AutoUpdateMode>HTTP</AutoUpdateMode>   <!--HTTP自动升级模式时的URL地址-->   <AutoUpdateHttpUrl>http://127.0.0.1:6600/AutoUpdateDir</AutoUpdateHttpUrl> </AutoUpdateConfig>

5.4、主程序

新建一个Windows 窗体MainForm,此处理仅需要一个空白窗体即可,作测试用。

MainForm.cs

5.5、应用程序主入口点

作用:检测应用程序是否需要自动更新,如里需要则检测远程服务端的版本号。假如远程服务端有新版本,则调用自动更新器AutoUpdater并向其传递4个参数。

C# WinForm通用自动更新器C# WinForm通用自动更新器

Main.cs

2)在binDebug下新建一个AutoUpdateDir文件夹,然后再在AutoUpdateDir下新建一个AutoUpdateFiles文件夹。

3)在AutoUpdaterTest中,将程序集版本及文件版本都改成1.0.0.1并重新生成,接着将AutoUpdaterTest.exe拷贝到AutoUpdateFiles下,最后将程序集版本及文件版本都改回1.0.0.0。

4)此时运行AutoUpdateXmlBuilder,点击生成更新XML文件即打包成功。程序会自动在AutoUpdateDir下生成打包信息文件AutoUpdateInfo.xml。

八、远程服务端配置

注:此处为本机测试。

1)在某个盘符如E盘下新建一个AutoUpdate文件夹,将AutoUpdateXmlBuilder打包文件夹AutoUpdateDir拷贝到AutoUpdate文件夹下。

2)在IIS中新建一个网站,对应的虚拟目录为E:AutoUpdate,同时将端口设置为6600。

3)运行AutoUpdaterTest,如出现自动更新器即代表成功。
