XML Linq 学习笔记

XML如下：

<?xml version="1.0" encoding="utf-8"?>
<Dishes>
    <Dish>
        <Name>清新芦荟</Name>
        <Category>饮料</Category>
        <Comment></Comment>
        <Score>5</Score>
    </Dish>
    <Dish>
        <Name>薄荷汽水</Name>
        <Category>饮料</Category>
        <Comment>本店特色</Comment>
        <Score>5</Score>
    </Dish>
</Dishes>

读取方法：

        public List<Dish> GetAllDishes()
        {
            List<Dish> dishList = new List<Dish>();
            string xmlFileName = System.IO.Path.Combine(Environment.CurrentDirectory, @"DataData.xml");
            //读取XML
            XDocument xDoc = XDocument.Load("xmlFileName");
            //返回Dishes集合
            var dishes = xDoc.Descendants("Dish");
            //循环集合 ，把数据添加到List中
            foreach(var d in dishes)
            {
                Dish dish = new Dish();
                dish.Name = d.Element("Name").Value;
                dish.Category = d.Element("Category").Value;
                dish.Comment = d.Element("Comment").Value;
                dish.Score = double.Parse(d.Element("Score").Value);
                dishList.Add(dish);
            }
            return dishList;
        }
