C#在Json反序列化中处理键的特殊字符

假设有如下Json 数据：

{
"id" : 1,
"@value" : "this a @",
"$p" : "my name a $"
}

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

public JsonTest{
public string id{get;set;}
}

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。

[DataContract]
public class jtest
{
[DataMember(Order = 0)]
public int id { get; set; }
[DataMember(Order = 1, Name = "@value")]
public string value { get; set; }
[DataMember(Order = 2, Name = "$p")]
public string _p { get; set; }
}

反序列化

jtest test = serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(jsonStr))) as jtest;
Console.WriteLine( test.value );

序列化

var stream = new MemoryStream();
serializer.WriteObject(stream, test);
byte[] dataBytes = new byte[stream.Length];
stream.Position = 0;
stream.Read(dataBytes, 0, (int)stream.Length);
string dataString = Encoding.UTF8.GetString(dataBytes);

完整测试类：

using System;
using System.Text;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string jsonStr = "{\"id\":1,\"@value\":\"this a @\",\"$p\":\"my name a $\"}";
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(jtest));

//反序列化
jtest test = serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(jsonStr))) as jtest;
Console.WriteLine( test.value );

//序列化
var stream = new MemoryStream();
serializer.WriteObject(stream, test);
byte[] dataBytes = new byte[stream.Length];
stream.Position = 0;
stream.Read(dataBytes, 0, (int)stream.Length);
string dataString = Encoding.UTF8.GetString(dataBytes);

Console.WriteLine(dataString);
Console.ReadKey();
}
}
[DataContract]
public class jtest
{
[DataMember(Order = 0)]
public int id { get; set; }
[DataMember(Order = 1, Name = "@value")]
public string value { get; set; }
[DataMember(Order = 2, Name = "$p")]
public string _p { get; set; }
}
}
