借鉴了圣殿骑士写的dll，更改了下载后删除old文件

1. 在引用中添加AutoUpdater.dll，代码中添加

Imports KnightsWarriorAutoupdater        '实现自动更新的dll

1. 服务器端配置文件 AutoupdateService.xml
   下面的代码示例会把文件夹tt以及里面的1.txt文件一起拷贝到客户端中，size为文件大小，并非占用空间，必须写对

<?xml version="1.0" encoding="utf-8"?><updateFiles>    <file  path="1.txt"  url="http://10.*.*.*:8011/SerialWrite/tt/1.txt"  lastver="3.2.1.2" size="8" needRestart="True"  /></updateFiles>

1. 客户端配置文件 AutoUpdater.config

<?xml version="1.0" encoding="utf-8"?><Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">  <Enabled>true</Enabled>  <ServerUrl>http://10.*.*.*:8011/SerialWrite/AutoupdateService.xml</ServerUrl>  <UpdateFileList>    <LocalFile path="1.txt" lastver="3.2.1.2" size="8" />  </UpdateFileList></Config>

1. 更新的代码
