C# 使用XML序列化对象（一）

在System.Xml.Serialization命名空间中提供了XML序列化类XmlSerializer用于将对象序列化为XML。

下面看一个最简单的例子：

    public class A
    {
        public int a
        {
            get;
            set;
        }
    }

    public string XmlSerialize<T>(T obj)
    {
        XmlSerializer xs = new XmlSerializer(typeof(T));

        using (TextWriter tw = new StringWriter())
        {
            xs.Serialize(tw, obj);
            return tw.ToString();
        }
    }

    public T XmlDeserialize<T>(string xml) where T : class
    {
        XmlSerializer xs = new XmlSerializer(typeof(T));
        using (TextReader tr = new StringReader(xml))
        {
            return xs.Deserialize(tr) as T;
        }
    }

    A objA = new A
    {
        a =
    };

    string xml = XmlSerialize(objA);

    var obj = XmlDeserialize<A>(xml);

上面代码序列化出来的xml如下：

<?xml version="1.0" encoding="utf-16"?>
<A xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <a>1</a>
</A>
