C#里 JSON 序列化 与 反序列化一、 VS2008以上版本 /// <summary> /// 序列 /// </summary> /// <typeparam name="T">对象类</typeparam> /// <param name="t">类对象</param> /// <returns>JSON字符串</returns> public static string JsonSerializer<T>(T t) { // 将对象序列化为 javaScript 对象表示法 (JSON)，并将 JSON 数据反序列化为对象。 DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); // 创建其支持存储区为内存的流 MemoryStream ms = new MemoryStream(); // 将指定对象序列化为 Javascript 对象表示法 (JSON) 数据，并将生成的 JSON 写入流中 ser.WriteObject(ms, t); // 写入字节数组转换字符串 string tojson = Encoding.UTF8.GetString(ms.ToArray()); // 关闭流 ms.Close(); // 返回JSON字符 return tojson; } /// <summary> /// 反序列化 /// </summary> /// <typeparam name="T">对象类</typeparam> /// <param name="strJson">要反序列的JSON字符串</param> /// <returns>返回对象</returns> public static T JsonDeserializer<T>(string strJson) { // 将对象序列化为 JavaScript 对象表示法 (JSON)，并将 JSON 数据反序列化为对象 DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); // 创建其支持存储区为内存的流 MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(strJson)); // 以 JSON（JavaScript 对象表示法）格式读取文档流，并返回反序列化的对象。 T obj = (T)ser.ReadObject(ms); // 返回 return obj; } /* * 调用方法： */ PRivate void button1_Click(object sender, EventArgs e) { student s = new student(); List<student> stu = new List<student>(); s.age = 11; s.height = 12; s.weight = 10; s.name = "tao"; stu.Add(s); student s2 = new student(); s2.age = 21; s2.height = 22; s2.weight = 20; s2.name = "jian"; stu.Add(s2); string json = JsonHelper.JsonSerializer < List<student>>(stu); listBox1.Items.Add(json); textBox1.Text = json; } private void button2_Click(object sender, EventArgs e) { List<student> s = JsonHelper.JsonDeserializer<List<student>>(textBox1.Text); listBox1.Items.Add(s[0].name); } private void button4_Click(object sender, EventArgs e) { student s = new student(); s.age = 11; s.height = 12; s.weight = 10; s.name = "tao222"; string json = JsonHelper.JsonSerializer<student>(s); listBox1.Items.Add(json); textBox1.Text = json; } private void button5_Click(object sender, EventArgs e) { student s = JsonHelper.JsonDeserializer<student>(textBox1.Text); listBox1.Items.Add(s.name); } private void button3_Click(object sender, EventArgs e) { DataTable dt = getDataTable(); string json = JsonHelper.JsonSerializer(dt); listBox1.Items.Add(json); textBox1.Text = json; } private void button6_Click(object sender, EventArgs e) { DataTable dt = JsonHelper.JsonDeserializer<DataTable>(textBox1.Text); listBox1.Items.Add(dt.Rows[0]["name"]); }
二 、 VS2005 版本 网上有个封装好的第三方很方便第三方下载连接：http://download.csdn.net/detail/xinping_168/4710720
