C# 序列化和反序列化

1. 序列化和反序列化：

定义：

　　序列化：将对象以字节流的形式保存到磁盘中或者在网络上进行传输；

　　反序列化：从字节流中解析出对象，但需要有对象的实例；

用法：

　　序列化：Newtonsoft.Json.JsonConvert.SerializeObject(Readings)

　　转换前：{ Systolic = {10}, Diastolic = {20}, Pulse = {30} }

　　转换后：{"Systolic":"10","Diastolic":"20","Pulse":"30"}　　

　　反序列化：Newtonsoft.Json.JsonConvert.DeserializeObject(Readings)

public class ReceiveBGEntity
{
        public int Systolic { get; set; }
        public int Diastolic { get; set; }
        public int Pulse { get; set; }

        public override string ToString()
        {
            return "Systolic:" + Systolic.ToString() + "; Date:" + Diastolic.ToString() + "; Pulse" + Pulse.ToString();
        }
}

class Program
{
        static void Main(string[] args)
        {
            string JSON_BG = "{'Systolic':'1','Diastolic':'5','Pulse':'7'}";
            ReceiveBGEntity BG = Newtonsoft.Json.JsonConvert.DeserializeObject<ReceiveBGEntity>(JSON_BG);
            Console.WriteLine(BG.ToString());
            Console.ReadLine();
        }
}

对于对象序列化和反序列化操作，经常操作的对象有实体对象，集合，DataTale及匿名对象，匿名对象解析方法DeserializeAnonymousType()的使用例子如下所示:

class Program
{
        static void Main(string[] args)
        {
            var AnonymousObj = new { ID = 0, Name = string.Empty, Words = string.Empty };
            string Results = Newtonsoft.Json.JsonConvert.SerializeObject(AnonymousObj);
            AnonymousObj = Newtonsoft.Json.JsonConvert.DeserializeAnonymousType("{\"ID\":\"20160427\",\"Name\":\"Tom\",\"Words\":\"Hello are you?\"}", AnonymousObj);
            Console.WriteLine(AnonymousObj.Name+"["+ AnonymousObj.ID + "],"+ AnonymousObj.Words);
            Console.ReadLine();
        }
}
