用.net代码修改XML文件不成功，请各位帮忙看看。:)

里面是一个改写XML文件的函数。用来改写WEB。CONFIG的。

当<Configuration带着xmlns时就失败了。如果不带xmlns的话就成功。

有办法不？


函数代码：
public void ModifyXMLSegment(string xmlFileName, string key, string strValue)
{
String TargetDir = "D:\\Projects\\Help2005\\UnitTest";
string XPath = "/configuration xmlns=\"http://schemas.microsoft.com/.NetConfiguration/v2.0\"/connectionStrings/add[@name='?']";
XPath = "/configuration/connectionStrings/add[@name='?']";
XmlDocument domWebConfig = new XmlDocument();

domWebConfig.Load((TargetDir + "\\" + xmlFileName));
XmlNode addKey = domWebConfig.SelectSingleNode((XPath.Replace("?", key)));
if (addKey == null)
{
throw new ArgumentException("Can't found XML segment <add name='" + key + "' connectionString=.../>");
}
addKey.Attributes["connectionString"].InnerText = strValue;
domWebConfig.Save((TargetDir + "\\" + xmlFileName));
}

调用的代码是：
ModifyXMLSegment("Web.Config", "SqlServer", "lkjalsdjf;lsadflk09u098080");


要修改的Web.Config内容如下：
<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<connectionStrings>
<add name="SqlServer" connectionString="Database=eHelpdesk_20061228;Server=Localhost;Integrated Security=SSPI;"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>

用不着那么麻烦，下面这样就行了
//打开配置文件
Configuration config = WebConfigurationManager.OpenWebConfiguration("~");
//获取appSettings节点
AppSettingsSection appSection = (AppSettingsSection)config.GetSection("appSettings");
//删除appSettings节点中的元素
appSection.Settings.Remove("addkey1");
//修改appSettings节点中的元素
appSection.Settings["addkey2"].Value = "Modify key2's value";
config.Save();
