By far the easiest approach is to use the JsonIgnore
attribute.
If I create a Terms
object like this:
Terms terms = new Terms() { SecretTerm = "Secret", Term = "Not secret" };
And if SecretTerm
looks like this:
[JsonIgnore]
[JsonProperty("SecretTerm")]
public string SecretTerm { get; set; }
Your serialized Json will look like this:
{
"Term": "Not secret"
}
If you want more fine-grained control you will have to create a custom converter.
Edit:
To more selectively output the object, you need the custom converter:
class TermsConverter : Newtonsoft.Json.JsonConverter
{
public override bool CanConvert(Type objectType)
{
return typeof(Terms) == objectType;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
throw new NotImplementedException();
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
Terms terms = (Terms)value;
writer.WriteStartObject();
writer.WritePropertyName("Term");
writer.WriteValue(terms.Term);
writer.WriteEndObject();
}
}
When serializing, you would do this:
var jsonRequest = JsonConvert.SerializeObject(this, new TermsConverter());
You'll note that I have left the ReadJson
unimplemented - I don't think it's necessary as you can easily deserialize a Terms
object without using a converter. In this case the SecretTerm
property would simply be empty.
By using the converter you won't need the [JsonIgnore]
attribute on the SecretTerm
property.
