如何用代码实现ASP.NET安装部署
如何用代码实现ASP.NET安装部署,相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。
ASP.NET安装部署代码实现之添加文件简介:
1. 将SQL Server生成的脚本文件db.sql添加到“Test Installer”项目
2. 将安装文件LisenceFile.rtf添加到“Test Installer”项目
3. 在用户界面编辑器中,选择许可协议,设置LisenceFile属性为LisenceFile.rtf文件
以下的ASP.NET安装部署代码实现是整个部署的最重要的一部分了
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 DBCustomActionClass DBCustomAction inherits System.Configuration.Install.Installer #region "组件设计器生成的代码 " public Sub New()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()Sub Dispose(ByVal disposing As Boolean) if disposing Then if Not (components Is Nothing) Then components.dispose() end If end If mybase.dispose(disposing) end Sub private components As System.ComponentModel.IContainer ﹤system.diagnostics.debuggerstepthrough()﹥ Private Sub InitializeComponent()Sub InitializeComponent() end Sub #end Region '执行sql 语句 private Sub ExecuteSql()Sub ExecuteSql(ByVal conn As String, ByVal DatabaseName As String, ByVal Sql As String) dim mySqlConnection As New SqlClient.SqlConnection(conn) dim Command As New SqlClient.SqlCommand(Sql, mySqlConnection) command.connection.open() command.connection.changedatabase(databasename) try command.executenonquery() finally 'close Connection command.connection.close() end Try end Sub public Overrides Sub Install()Sub Install(ByVal stateSaver As System.Collections.IDictionary) MyBase.Install(stateSaver) ' ----------ASP.NET安装部署代码实现建立数据库------------ try dim connStr As String = String.Format("data source={0}; user id={1};password={2}; persist security info=false;packet size=4096", Me.Context.Parameters.Item("server"), Me.Context.Parameters.Item("user"), Me.Context.Parameters.Item("pwd")) '根据输入的数据库名称建立数据库 executesql(connstr, "master", "CREATE DATABASE " + Me.Context.Parameters.Item("dbname")) 'ASP.NET安装部署代码实现之调用osql执行脚本 dim sqlProcess As New System.Diagnostics.Process sqlprocess.startinfo.filename = "osql.exe " sqlprocess.startinfo.arguments = String.Format(" -U {0} -P {1} -d {2} -i {3}db.sql", Me.Context.Parameters.Item("user"), Me.Context.Parameters.Item("pwd"), Me.Context.Parameters.Item("dbname"), Me.Context.Parameters.Item("targetdir")) sqlprocess.startinfo.windowstyle = ProcessWindowStyle.Hidden sqlprocess.start() sqlprocess.waitforexit() '等待执行 sqlprocess.close() 'ASP.NET安装部署代码实现之删除脚本文件 dim sqlFileInfo As New System.IO.FileInfo(String.Format("{0}db.sql", Me.Context.Parameters.Item("targetdir"))) if sqlFileInfo.Exists Then sqlfileinfo.delete() end If catch ex As Exception throw ex end Try ' -ASP.NET安装部署代码实现之将连接字符串写入Web.config-- try dim FileInfo As System.IO.FileInfo = New System.IO. FileInfo(Me.Context.Parameters.Item("targetdir") & "\web.config") if Not FileInfo.Exists Then throw New InstallException("没有找到配置文件") end If '实例化xml文档 dim XmlDocument As New System.Xml.XmlDocument xmldocument.load(fileinfo.fullname) '查找到appsettings中的节点 dim Node As System.Xml.XmlNode dim FoundIt As Boolean = False for Each Node In XmlDocument.Item("configuration").Item("appSettings") if Node.Name = "add" Then if Node.Attributes.GetNamedItem("key").Value = "connString" Then 'ASP.NET安装部署代码实现之写入连接字符串 node.attributes.getnameditem("value").value = String. Format("Persist Security Info=False;Data Source={0}; Initial Catalog={1};User ID={2};Password={3}; Packet Size=4096;Pooling=true;Max Pool Size=100; Min Pool Size=1", _ me.context.parameters.item("server"), Me.Context.Parameters.Item("dbname"), Me.Context.Parameters.Item("user"), Me.Context.Parameters.Item("pwd")) foundit = True end If end If next Node if Not FoundIt Then throw New InstallException("web.Config 文件没有包含connString连接字符串设置") end If xmldocument.save(fileinfo.fullname) catch ex As Exception throw ex end Try end Sub end Class
有点难度的就是那个Process类,它调用了osql.exe程序,来执行sql语句osql -U,-P,,-d,-i。
web.config的修改代码是利用xml的语法实现。不是很难理解。
