谁能告诉我这个怎么做哦
要求读取XML里面的内容 链接数据库<?xml version="1.0" encoding="utf-8"?>
<Config>
<ServerAddress>.</ServerAddress>
<DBName>DBabc</DBName>
<UserID>sa</UserID>
<PassWord>sa</PassWord>
</Config>
这个是XML里面的内容哦
文件名可以随便取个
--------------------------------------------
要完成下面的内容怎么完成哦。能够读取到XML 连接上数据库，下面代码要完善哦 求指点

{
PhysicsPath = HttpContext.Current.Server.MapPath("Config.xml").ToString();
if (File.Exists(PhysicsPath))
{
//完善代码，加载XmlDom
}
}

--------------------编程问答-------------------- 有没有人会呀？ --------------------编程问答-------------------- <ServerAddress>.</ServerAddress>
<DBName>DBabc</DBName>
<UserID>sa</UserID>
<PassWord>sa</PassWord>
if (File.Exists(PhysicsPath))--------------------编程问答--------------------
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(PhysicsPath);
var address = xmlDoc.SelectSingleNode("//ServerAddress").Value;
var dbName = xmlDoc.SelectSingleNode("//DBName").Value;
var userId = xmlDoc.SelectSingleNode("//UserID").Value;
var passwd = xmlDoc.SelectSingleNode("//PassWord").Value;
}
下面的那些静态方法里面应该怎么填呢
//完善代码
的部分。谢谢了哦 高手 --------------------编程问答-------------------- 自己设个私有类成员，return。
举个例子：
private static string _address;
...
if (File.Exists(PhysicsPath))
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(PhysicsPath);
_address = xmlDoc.SelectSingleNode("//ServerAddress").Value;
}
...
public static string GetServerAddress()
{
return _address;
}
--------------------编程问答-------------------- +1.
补充：.NET技术 , C#
