//读配置文件
XmlDocument doc = new XmlDocument();
doc.Load("blog.xml");
XmlNode url = doc.SelectSingleNode("博客/广告地址");
texturl.Text = url.InnerText;
 
XmlNode Name = doc.SelectSingleNode("博客/用户名1");
name = Name.InnerText;
 
XmlNode Password = doc.SelectSingleNode("博客/密码1");
password = Password.InnerText;
 
XmlNode dbid = doc.SelectSingleNode("博客/DBID");
DBID = int.Parse(dbid.InnerText);
 
//写配置文件
XmlDocument doc = new XmlDocument();
doc.Load("blog.xml");
XmlNode xiugai = doc.SelectSingleNode("博客");
xiugai["DBID"].InnerText = DBID.ToString();   //修改值
doc.Save("blog.xml");
