C#在Json反序列化中处理键的特殊字符

    • 假设有如下Json 数据:

       

      view sourceprint?
      1.{
      2."id" : 1,
      3."@value" "this a @",
      4."$p" "my name a $"
      5.}

      通常情况下,在Json反序列化时,将Json映射到序列化的类,无需指定其名称。如
      view sourceprint?
      1.public JsonTest{
      2.public string id{get;set;}
      3.}

      在反序列化时会自动将Json中的ID与类中的ID对应。
      但是当键有特殊字符时,如 $ , @ 等,无法定义类的属性中含有特殊字符,
      因此,需要使用 [DataContract] 和 [DataMember] 来定义数据协定

      view sourceprint?
      01.[DataContract]
      02.public class jtest
      03.{
      04.[DataMember(Order = 0)]
      05.public int id { getset; }
      06.[DataMember(Order = 1, Name = "@value")]
      07.public string value { getset; }
      08.[DataMember(Order = 2, Name = "$p")]
      09.public string _p { getset; }
      10.}

      反序列化

      view sourceprint?
      1.jtest test = serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(jsonStr))) as jtest;
      2.Console.WriteLine( test.value );

      序列化
      view sourceprint?
      1.var stream = new MemoryStream();
      2.serializer.WriteObject(stream, test);
      3.byte[] dataBytes = new byte[stream.Length];
      4.stream.Position = 0;
      5.stream.Read(dataBytes, 0, (int)stream.Length);
      6.string dataString = Encoding.UTF8.GetString(dataBytes);

      完整测试类:

      view sourceprint?
      01.using System;
      02.using System.Text;
      03.using System.Runtime.Serialization;
      04.using System.Runtime.Serialization.Json;
      05.using System.IO;
      06. 
      07. 
      08.namespace ConsoleApplication1
      09.{
      10.class Program
      11.{
      12.static void Main(string[] args)
      13.{
      14.string jsonStr = "{\"id\":1,\"@value\":\"this a @\",\"$p\":\"my name a $\"}";
      15.DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(jtest));
      16. 
      17.//反序列化
      18.jtest test = serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(jsonStr))) as jtest;
      19.Console.WriteLine( test.value );
      20. 
      21.//序列化
      22.var stream = new MemoryStream();
      23.serializer.WriteObject(stream, test);
      24.byte[] dataBytes = new byte[stream.Length];
      25.stream.Position = 0;
      26.stream.Read(dataBytes, 0, (int)stream.Length);
      27.string dataString = Encoding.UTF8.GetString(dataBytes);
      28. 
      29.Console.WriteLine(dataString);
      30.Console.ReadKey();
      31.}
      32.}
      33.[DataContract]
      34.public class jtest
      35.{
      36.[DataMember(Order = 0)]
      37.public int id { getset; }
      38.[DataMember(Order = 1, Name = "@value")]
      39.public string value { getset; }
      40.[DataMember(Order = 2, Name = "$p")]
      41.public string _p { getset; }
      42.}
      43.}
