制作的安装程序如何改WebConfig的内容？

[shooper]

比如说在安装程序根据用户的选择来连接数据库，再把该数据库连接代码写入到webconfig的appSettings中，怎么做啊

StringBuilder sb2 = new StringBuilder();
sb2.Append("data source=");
sb2.Append(temp1);
sb2.Append(";");
sb2.Append("initial catalog=");
sb2.Append(temp2);
sb2.Append(";persist security info=False;");
sb2.Append("user id=");
sb2.Append(temp3);
sb2.Append(";");
sb2.Append("pwd=");
sb2.Append(temp4);
sb2.Append(";packet size=4096");

StringBuilder xmlpath = new StringBuilder();
xmlpath.Append(filepath);
xmlpath.Append("\\");
xmlpath.Append("Web.config");

XmlDocument doc = new XmlDocument();
doc.Load(xmlpath.ToString()); //加载Web.Config
XmlElement elem=doc.DocumentElement;

XmlElement newelem = doc.CreateElement ("appSettings");
XmlElement elem1 = doc.CreateElement("add");

XmlNodeList nodes = doc.SelectNodes("/configuration/appSettings/add");

//连接字符串赋值 foreach(XmlNode node in nodes)
{
switch (node.Attributes["key"].Value)
{
case "strConnection":
node.Attributes["value"].Value = sb2.ToString();
break;
default:
// Don't do anything
break;
}
}
doc.Save(xmlpath.ToString()); //保存修改

可以直接当可执行脚本用吗,还是需要iis支持？

就是在安装的时候在安装程序运行时，根据需要修改webconfig

怎么做的
