请教高手如何用c#修改XML文件的标记里的内容

我想用程序修改如下xml文件的内容：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="2008" connectionString="text"/>
</connectionStrings>
</configuration>
我想修改的内容是：connectionSring里的"text"内容，请教高手如何操作?

Answer 1

XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Load(Server.MapPath("***.xml"));
XmlNodeList list = XMLDoc.GetElementsByTagName("add");

for (int i = 0; i < list.Count; i++)
{
if (list[i].Attributes[0].Value == "2008")
{
list[i].Attributes[1].Value = "text";//在这里改
}
}
StreamWriter swriter=new StreamWriter(Server.MapPath("******.xml"));
XmlTextWriter xw = new XmlTextWriter(swriter);
xw.Formatting = Formatting.Indented;
XMLDoc.WriteTo(xw);
xw.Close();
swriter.Close();

Answer 2

string strxml = @"<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="2008" connectionString="text"/>
</connectionStrings>
</configuration>";
XmlDocument XMLDoc = new XmlDocument();
XMLDoc.Loadxml(strxml );

XMLDoc.selectsinglenode("connectionSring").InerText = "text1";
