我有一个这样的POCO:
public class Process
{
public Process() { }
[DataMember(Name = "lang_code")]
public string LCode { get; set; }
[DataMember(Name = "data_currency")]
public string Currency { get; set; }
[DataMember(Name = "country_code")]
public string CCode { get; set; }
public override string ToString()
{
return JsonConvert.SerializeObject(this);
}
}
现在,当我序列化我的POCO时,我得到了这样的json,它有字段名:
{"LCode":"en-US","Currency":"USD","CCode":"IN"}
有什么方法可以像序列化POCO之后的DataMember
字段那样获得它吗?如下所示:
{"lang_code":"en-US","data_currency":"USD","country_code":"IN"}
下面是我们的代码:
ProcessStr = ExtractHeader(headers, PROCESS_HEADER);
Console.WriteLine(ProcessStr);
if (!string.IsNullOrWhiteSpace(ProcessStr))
{
Process = DeserializeJson<Process>(ProcessStr);
if (Process != null && !string.IsNullOrWhiteSpace(Process.Gold))
{
Process.Gold = HttpUtility.HtmlEncode(Process.Gold);
}
ProcessStr = Process.ToString();
Console.WriteLine(ProcessStr);
}
private T DeserializeJson<T>(string str) where T : new()
{
try
{
return Utf8Json.JsonSerializer.Deserialize<T>(str);
}
catch (Exception e)
{
return new T();
}
}

看起来您使用了两个不同的包:Newtonsoft.Json
序列化和Utf8Json
反序列化。它们使用不同的注释。你可以让它工作,但它可能更容易选择一个或另一个。
Newtonsoft.Json
使用JsonProperty
属性,而Utf8Json
使用DataMember
属性。
using System;
using System.Diagnostics;
using System.Runtime.Serialization;
using Newtonsoft.Json;
using Utf8Json;
namespace JSONPropertyTest
{
public class Process
{
public Process() { }
[JsonProperty("lang_code")]
[DataMember(Name = "lang_code")]
public string LCode { get; set; }
[JsonProperty("data_currency")]
[DataMember(Name = "data_currency")]
public string Currency { get; set; }
[JsonProperty("country_code")]
[DataMember(Name = "country_code")]
public string CCode { get; set; }
public override string ToString()
{
return JsonConvert.SerializeObject(this);
}
}
class Program
{
static private T DeserializeJson<T>(string str) where T : new()
{
try
{
return Utf8Json.JsonSerializer.Deserialize<T>(str);
}
catch (Exception e)
{
return new T();
}
}
static void Main(string[] args)
{
var test = new Process { LCode = "en-US",Currency = "USD", CCode = "IN" };
var json = test.ToString();
Console.WriteLine($"serialized={test}");
var deserialized = DeserializeJson<Process>(json);
Debug.Assert(test.CCode == deserialized.CCode);
Debug.Assert(test.LCode == deserialized.LCode);
Debug.Assert(test.Currency == deserialized.Currency);
Console.WriteLine($"deserialized={deserialized}");
}
}
}
要使用Utf8Json
,您需要更新ToString
方法,这是您展示的代码中唯一依赖Newtonsoft.Json
的方法。看起来是这样的:
public class Process
{
public Process() { }
[DataMember(Name = "lang_code")]
public string LCode { get; set; }
[DataMember(Name = "data_currency")]
public string Currency { get; set; }
[DataMember(Name = "country_code")]
public string CCode { get; set; }
public override string ToString()
{
return Utf8Json.JsonSerializer.ToJsonString(this);
}
}
