xml格式如下：

<?xml version="1.0"?>
<products>
<product name="West Side Story" price="9.99" supplierId="1" />
<product name="Assassins" price="14.99" supplierId="2" />
<product name="Frogs" price="13.99" supplierId="1" />
<product name="Sweeney Todd" price="10.99" supplierId="3" />
</products>

product 对象如下：

public class Product
{
public string Name { get; set; }

public decimal Price { get; set; }

public decimal SupplierId { get; set; }
}

利用.net中的XmlSerializer将xml转换成对象

1、首先要在Product、Products类中的每个属性上加上与xml对应的描述字段，如下代码：

    [XmlRoot("products")]
    public class Products
    {
        [XmlElement("product")]
        public Product[] Items { get; set; }
    }

     public class Product
      {
          [XmlAttribute(AttributeName = "name")]
          public string Name { get; set; }
  
          [XmlAttribute(AttributeName = "price")]
          public decimal Price { get; set; }
  
          [XmlAttribute(AttributeName = "supplierId")]
         public decimal SupplierId { get; set; }
     }

注意AttributeName一定要和xml中的一致。

2、相应的对应关系建立好了之后，下面就来进行读取反序列化，代码如下：

private static IList<Product> products=new List<Product>(); static LoadXml() { try { using (TextReader reader = new StreamReader("data.xml")) { var serializer = new XmlSerializer(typeof(Products)); var items = (Products)serializer.Deserialize(reader); if (items != null) { products = items.Items; } } } catch (Exception ex) { Console.WriteLine("出错了，" + ex.Message); } }
