Wyłącz właściwości z wartością null na ASP.NET Web API
I ' ve created an ASP.Net projekt WEB API, który będzie wykorzystywany przez aplikację mobilną. Potrzebuję odpowiedzi json, aby pominąć właściwości null zamiast zwracać je jako property: null

W WebApiConfig
:
config.Formatters.JsonFormatter.SerializerSettings =
new JsonSerializerSettings {NullValueHandling = NullValueHandling.Ignore};
Lub, jeśli chcesz mieć większą kontrolę, możesz zastąpić cały formatter:
var jsonformatter = new JsonMediaTypeFormatter
{
SerializerSettings =
{
NullValueHandling = NullValueHandling.Ignore
}
};
config.Formatters.RemoveAt(0);
config.Formatters.Insert(0, jsonformatter);

options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
});

Jeśli używasz vnext, w projektach vNext web api, dodaj ten kod do uruchamiania.plik cs.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().Configure<MvcOptions>(options =>
{
int position = options.OutputFormatters.FindIndex(f => f.Instance is JsonOutputFormatter);
var settings = new JsonSerializerSettings()
{
NullValueHandling = NullValueHandling.Ignore
};
var formatter = new JsonOutputFormatter();
formatter.SerializerSettings = settings;
options.OutputFormatters.Insert(position, formatter);
});
}
