读取方法



static Dictionary<string, string> list = new Dictionary<string, string>();
    static void Main(string[] args)
    {
      XElement root = XElement.Load("Languages.xml");

      var custs = (from c in root.Elements("DbTarget")
            where c.Attribute("From").Value.Equals("SQL") && c.Attribute("To").Value.Equals("SqlClient")
            select c).ToList();

      foreach (XElement node in custs.Elements("Type"))
      {
        list.Add(node.Attribute("From").Value, node.Attribute("To").Value);
      }

      Console.ReadKey();
    }
试试其它关键字
　数据类型转换　
同语言下
可能有用的
