Web API serialize properties starting from lowercase letter
Solution 1:
If you want to change serialization behavior in Newtonsoft.Json aka JSON.NET, you need to create your settings:
var jsonSerializer = JsonSerializer.Create(new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
NullValueHandling = NullValueHandling.Ignore // ignore null values
});
You can also pass these settings into JsonConvert.SerializeObject
:
JsonConvert.SerializeObject(objectToSerialize, serializerSettings);
For ASP.NET MVC and Web API. In Global.asax:
protected void Application_Start()
{
GlobalConfiguration.Configuration
.Formatters
.JsonFormatter
.SerializerSettings
.ContractResolver = new CamelCasePropertyNamesContractResolver();
}
Exclude null values:
GlobalConfiguration.Configuration
.Formatters
.JsonFormatter
.SerializerSettings
.NullValueHandling = NullValueHandling.Ignore;
Indicates that null values should not be included in resulting JSON.
ASP.NET Core
ASP.NET Core by default serializes values in camelCase format.
Solution 2:
For MVC 6.0.0-rc1-final
Edit Startup.cs, In the ConfigureServices(IserviceCollection)
, modify services.AddMvc();
services.AddMvc(options =>
{
var formatter = new JsonOutputFormatter
{
SerializerSettings = {ContractResolver = new CamelCasePropertyNamesContractResolver()}
};
options.OutputFormatters.Insert(0, formatter);
});
Solution 3:
ASP.NET CORE 1.0.0 Json serializes have default camelCase. Referee this Announcement
Solution 4:
If you want to do this in the newer (vNext) C# 6.0, then you have to configure this through MvcOptions
in the ConfigureServices
method located in the Startup.cs
class file.
services.AddMvc().Configure<MvcOptions>(options =>
{
var jsonOutputFormatter = new JsonOutputFormatter();
jsonOutputFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
jsonOutputFormatter.SerializerSettings.DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Ignore;
options.OutputFormatters.Insert(0, jsonOutputFormatter);
});
