采用解决方案包自动修改sharepoint站点的web.config参数

每次修改配置sharepoint站点的web.config参数很是繁琐,如果有多个web前段,比如:有3台web端部署做了NLB,每次部署安装的需要部署3台前段。不但麻烦,而且一旦一台少部署了些参数就会出现访问错误。最近想用代码实现自动部署修改,查询了MSDN,原来有SPWebApplication对象。

采用自己的XML文件进行解析,并用在Feature上添加事件接收器。如下图:

1、自定义的XML定义如下:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <!-- 应用程序集 -->
    <compilation>
      <assemblies>
        <add assembly="TCL.EP.WebServices, Version=1.0.0.0, Culture=neutral, PublicKeyToken=3eacd9f89e4e2d7c" />
        <add assembly="TCL.EP.GPortal.UI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=bb2d8d9d97c5e2f1" />
        <add assembly="TCL.EP.SPCommon, Version=1.0.0.0, Culture=neutral, PublicKeyToken=99579db435012b8e" />
        <add assembly="AspNetPager, Version=7.4.3.0, Culture=neutral, PublicKeyToken=fb0a0fe055d40fd4" />
      </assemblies>
    </compilation>
    <!-- 应用程序集 -->
  </system.web>
  <appSettings>
    <add key="DocsiteUrl" value="http://moss:8002" />
    <add key="DocwebUrl" value="" />
  </appSettings>
  <!-- 数据库连接字符串-->
  <connectionStrings>
    <add name="strConn" connectionString="Data Source=.;Initial Catalog=test;Integrated Security=false;User Id=sa;Password=Passw0rd!" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <!-- 数据库连接字符串-->
</configuration>

?

2、事件接收器代码如下:

using System;
using System.Runtime.InteropServices;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using Microsoft.SharePoint.Administration;
using System.Collections.Generic;
using System.Xml;
