在.net 2003上创建infopath项目

在infopath模板自身的脚本编辑器里用js写业务代码有一年了，代码的难度一般，就是使用一些对象对XML结点进行增，删，修，查，复制，装载，翻译等操作，主要还是利用js语法和业务逻辑编程。
XDocument,UI,View,selectSingleNode,selectNodes,appendChild,replaceChild
removeChild,removeAll,cloneNode,nextSibling,transformNode,loadXML……

有时执行js代码时感觉效率不高，于是用net 2003结合IPVSPROJ2003.exe，在net中建模板，C#作为托管语言。感觉不错，好多方法和属性在打点后会自动出来，快……。调试也容易。
下面是我写的一段，输出webservice拉过来的产品数据：

using System;
using info = Microsoft.Office.Interop.InfoPath.SemiTrust;
using Microsoft.Office.Interop.InfoPath.SemiTrust;

// Office 集成属性，指明表单的 startup 类。不要修改。
[assembly: System.ComponentModel.DescriptionAttribute("InfoPathStartupClass, Version=1.0, Class=InfoPathProject1.InfoPathProject1")]
