[冷枫].NET平台下WEB应用程序的部署的例子

将代码添加到安装程序类中，dbcustomaction.vb类
Imports System.ComponentModel

imports System.Configuration.Install

imports System.IO

imports System.Reflection

<runinstaller(true)> Public Class DBCustomAction

#region "组件设计器生成的代码 "

public Sub New()

mybase.new()

'该调用是组件设计器所必需的

initializecomponent()

'在 InitializeComponent() 调用之后添加任何初始化

end Sub

' Installer 重写 dispose 以清理组件列表。

protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

if disposing Then

if Not (components Is Nothing) Then

end If

end If

mybase.dispose(disposing)

end Sub

private components As System.ComponentModel.IContainer

<system.diagnostics.debuggerstepthrough()> Private Sub InitializeComponent()

#end Region
