I have a web-API project and a simple class with a few properties, some are marked <JsonIgnore>.
In my MVC-controller I put Return Json(instanceOfMyClass, JsonRequestBehavior.AllowGet). All members are serialized.
I put Return Json(Of MyClass)(instanceOfMyClass) in my WEBAPI-controller. Only the members I intend to serialize are present.
How can I ignore these properties independent of the controller that's going to serialize.
The JsonResult in MVC does not actually use JSON.NET which is why [JsonIgnore] is not working. Instead it uses the JavaScriptSerializer class.
To make the JavaScriptSerializer skip a property, you can you the [ScriptIgnore] attribute on your model property.
An alternative would be to make a custom ActionResult that uses JSON.NET's JsonConvert to serialize the object which would then honor the [JsonIgnore] attribute.
In case it helps anyone, it didn't seem possible or straightforward to use [ScriptIgnore] in my .net Core app, so I did this:
public IActionResult Index()
{
Response.ContentType = "text/json";
return Content(JsonConvert.SerializeObject(instanceOfMyClass));
}
