#region 读写xml文件的2个小函数，2005 4 2 by hyc

public void SetXmlFileValue(string xmlPath,string AppKey,string AppValue)/写xmlPath是文件路径+文件名，AppKey是 Key Name，AppValue是Value
{
XmlDocument xDoc = new XmlDocument();
xDoc.Load(xmlPath);
XmlNode xNode;
XmlElement xElem1;
XmlElement xElem2;

if ( xElem1 != null )

xElem1.SetAttribute(value,AppValue);
}
else
{
xElem2 = xDoc.CreateElement(add);
xElem2.SetAttribute(key,AppKey);
xElem2.SetAttribute(value,AppValue);
xNode.AppendChild(xElem2);
}
xDoc.Save(xmlPath);
}

public void GetXmlFileValue(string xmlPath,string AppKey,ref string AppValue)/读xmlPath是文件路径+文件名，AppKey是 Key Name，AppValue是Value
{
XmlDocument xDoc = new XmlDocument();
xDoc.Load(xmlPath);
XmlNode xNode;
XmlElement xElem1;

xNode = xDoc.SelectSingleNode(/appSettings);

}
else
