借鑑了聖殿騎士寫的dll，更改了下載後刪除old文件

1. 在引用中添加AutoUpdater.dll，代碼中添加

Imports KnightsWarriorAutoupdater        '實現自動更新的dll

1. 服務器端配置文件 AutoupdateService.xml
   下面的代碼示例會把文件夾tt以及裏面的1.txt文件一起拷貝到客戶端中，size爲文件大小，並非佔用空間，必須寫對

<?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. 客戶端配置文件 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. 更新的代碼

Dim bHasError As Boolean = False
Dim autoUpdater As IAutoUpdater = New AutoUpdater()
Try
    autoUpdater.Update()
Catch ex As WebException
    MessageBox.Show("連接自動升級服務器出錯，請檢查網絡連接或聯繫軟件提供者。(Connect remote update server fail.)", "更新程序(UPDATE SOFTWRAE)", MessageBoxButtons.OK, MessageBoxIcon.Error)
    bHasError = True
Catch ex As XmlException
    MessageBox.Show("服務器上的升級文件(AutoupdateService.xml)出錯。(Download the upgrade file error.)", "更新程序(UPDATE SOFTWRAE)", MessageBoxButtons.OK, MessageBoxIcon.Error)

Catch ex As Exception
    MessageBox.Show("更新程序出錯。(An error occurred during the upgrade process.)", "更新程序(UPDATE SOFTWRAE)", MessageBoxButtons.OK, MessageBoxIcon.Error)
    bHasError = True
Finally
    If bHasError = True Then
        Try
            autoUpdater.RollBack()
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End If
End Try
