JObject&；使用JSON进行CamelCase转换.净值

如何将通用JObject转换为camelCase纯json字符串？我尝试过JsonSerializerSettings，但不起作用(Newtonsoft.Json 4.5.11(

[Test]
public void should_convert_to_camel_case()
{
    var serializer = JsonSerializer.Create(new JsonSerializerSettings()
    {
        ContractResolver = new CamelCasePropertyNamesContractResolver()
    });
    var jo = new JObject();
    jo["CamelCase"] = 1;
    var stringWriter = new StringWriter();
    var writer = new JsonTextWriter(stringWriter);
    serializer.Serialize(writer,jo);
    var serialized = stringWriter.ToString();
    Assert.AreEqual("{'"camelCase'":1}", serialized);
}

JObject&；使用JSON进行CamelCase转换.净值

这个问题从一个JObject开始，想要处理一个骆驼大小写的JSON对象。如果你实际上是从一个对象开始，并且想要到达一个已经基于camelbased的JObject，那么你可以这样做：

var serializer = new JsonSerializer()
{
    ContractResolver = new CamelCasePropertyNamesContractResolver()
};
var jo = JObject.FromObject(someDataContract, serializer);

由此产生的"jo"将以骆驼为基础。

根据这个Json。NET问题，当以这种方式序列化JObject时，合同解析程序被忽略：

序列化JObject时，契约解析器似乎被忽略了。这肯定不是应该的样子吗？

这确实有道理，但恐怕这是一个太大的突破性变化。

受该页面上的变通方法的启发，您可以这样做：

var jo = new JObject();
jo["CamelCase"] = 1;
string json = JsonConvert.SerializeObject(jo);
var jObject = JsonConvert.DeserializeObject<ExpandoObject>(json);
var settings = new JsonSerializerSettings()
{
    ContractResolver = new CamelCasePropertyNamesContractResolver()
};
var serialized = JsonConvert.SerializeObject(jObject, settings);
Assert.AreEqual("{'"camelCase'":1}", serialized);

编辑：

Dictionary<string, object>的优点。因此，这样做可以跳过额外的JsonConvert.SerializeObject，但也减少了对ExpandoObject的需求，这在使用时非常重要。NET 3.5。

Dictionary<string, object> jo = new Dictionary<string, object>();
jo.Add("CamelCase", 1);
var settings = new JsonSerializerSettings()
{
    ContractResolver = new CamelCasePropertyNamesContractResolver()
};
var serialized = JsonConvert.SerializeObject(jo, settings);
Assert.AreEqual("{'"camelCase'":1}", serialized);

截至2013年5月8日，James Newton King关于Json 5.0版本的博客文章。NET，这已经通过添加"DefaultSettings"来解决。下面是该页中的示例，但请阅读该页以了解第三方库的详细信息。

// settings will automatically be used by JsonConvert.SerializeObject/DeserializeObject
JsonConvert.DefaultSettings = () => new JsonSerializerSettings
    {
    Formatting = Formatting.Indented,
    ContractResolver = new CamelCasePropertyNamesContractResolver()
    };
Employee e = new Employee
    {
    FirstName = "Eric",
    LastName = "Example",
    BirthDate = new DateTime(1980, 4, 20, 0, 0, 0, DateTimeKind.Utc),
    Department = "IT",
    JobTitle = "Web Dude"
    };
string json = JsonConvert.SerializeObject(e);
// {
//   "firstName": "Eric",
//   "lastName": "Example",
//   "birthDate": "1980-04-20T00:00:00Z",
//   "department": "IT",
//   "jobTitle": "Web Dude"
// }

public static JsonSerializer FormattingData()
{
   var jsonSerializersettings = new JsonSerializer {
   ContractResolver = new CamelCasePropertyNamesContractResolver() };
   return jsonSerializersettings;
}

public static JObject CamelCaseData(JObject jObject) 
{   
   var expandoConverter = new ExpandoObjectConverter();
   dynamic camelCaseData = 
   JsonConvert.DeserializeObject(jObject.ToString(), 
   expandoConverter); 
   return JObject.FromObject(camelCaseData, FormattingData());

}
