C#で外部から取得したXMLをモデルクラスにマッピングする方法

Last updated at 2016-05-18Posted at 2016-05-18

[メモ書き]

たとえば下記のようなXMLが取得できる場合を想定

<report>
  <head>
    <title>Title</title>
    <type>Type</type>
  </head>
  <body>
    <item>
      <name>A</name>
      <age>20</age>
    </item>
    <item>
      <name>B</name>
      <age>22</age>
    </item>
  </body>
</report>

下記クラスを定義する

model.cs

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

namespace Test
{
	[XmlRoot("report")]
	public class Report
	{
		[XmlElement("head")]
		public Head head;

		[XmlElement("body")]
		public Body body;
	}

	public class Head
	{
		[XmlElement("title")]
		public string title;

		[XmlElement("type")]
		public string type;
	}

	public class Body
	{
		[XmlElement("item")]
		public List<Item> items;
	}

	public class Item
	{
		[XmlElement("name")]
		public string name;

		[XmlElement("age")]
		public int age;
	}
}

main.cs

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

namespace Test
{
	public void main() 
	{
		var url = "{url}";
		HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
		HttpWebResponse response = request.GetResponse() as HttpWebResponse;
		var stream = response.GetResponseStream();
		XmlSerializer serializer = new XmlSerializer(typeof(Report));
		var report = serializer.Deserialize(stream) as Report;
	}
}
