C#的XML序列化及反序列化

　　webservice在工作中用到的很多，基本都是以XML格式問通訊內容，其中最關鍵的就是XML串的序列化及反序列化。

　　XML的運用中有兩種信息傳遞，一種為XML的請求信息，另一種為返回信息，要運用XML，首先要為這兩種返回信息新建實體類。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Xml.Serialization;

namespace Test1
{
    [Serializable]
    public class RequestBase
    {
        [XmlElement(Order = 1)]
        public string Name
        {
            get;
            set;
        }

        [XmlElement(Order = 2)]
        public string Age
        {
            get;
            set;
        }

    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Xml.Serialization;

namespace Test1
{
    [Serializable]
    public class ResponseBase
    {
        [XmlElement(Order = 1)]
        public string Information
        {
            get;
            set;
        }
    }
}

　　然后編寫將XML序列化和反序列化的方法：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Xml.Serialization;
using System.IO;

namespace Test1
{
    public class Function
    {
        //反序列化
        public static T Deserialize<T>(string xml)
        {
            XmlSerializer xs = new XmlSerializer(typeof(T));
            StringReader sr = new StringReader(xml);
            T obj = (T)xs.Deserialize(sr);
            sr.Close();
            sr.Dispose();
            return obj;
        }

        //序列化
        public static string Serializer<T>(T t)
        {
            XmlSerializerNamespaces xsn = new XmlSerializerNamespaces();
            xsn.Add(string.Empty, string.Empty);
            XmlSerializer xs = new XmlSerializer(typeof(T));
            StringWriter sw=new StringWriter();
            xs.Serialize(sw, t, xsn);
            string str = sw.ToString();
            sw.Close();
            sw.Dispose();
            return str;
        }
    }
}

　　然后再具體實現將請求信息通過代碼處理變成返回信息的方法：

public string Test(string xml)
        {
            RequestBase request = Function.Deserialize<RequestBase>(xml);
            ResponseBase response = new ResponseBase();
            response.Information = "姓名：" + request.Name + " 年齡為：" + request.Age;
            return Function.Serializer<ResponseBase>(response);
        }

　　示例XML：<?xml version="1.0" encoding="utf-8"?><RequestBase><Name>逗你玩</Name><Age>25</Age></RequestBase>

　　返回值為：

<string xmlns="http://tempuri.org/">
<?xml version="1.0" encoding="utf-16"?> <ResponseBase> <Information>姓名：逗你玩 年齡為：25</Information> </ResponseBase>
</string>
