Private setters in Json.Net

Question

I know there's an attribute to handle private setters but I kind of want this behavior as a default, is there a way to accomplish this? Except tweaking the source. Would be great if there was a setting for this.

Answer 1

I came here looking for the actual attribute that makes Json.NET populate a readonly property when deserializing, and that's simply [JsonProperty], e.g.:

[JsonProperty] public Guid? ClientId { get; private set; } 

Alternative Solution

Just provide a constructor that has a parameter matching your property:

public class Foo {     public string Bar { get; }      public Foo(string bar)     {         Bar = bar;     } } 

Now this works:

string json = "{ \"bar\": \"Stack Overflow\" }";  var deserialized = JsonConvert.DeserializeObject<Foo>(json); Console.WriteLine(deserialized.Bar); // Stack Overflow 

I prefer this approach where possible since:

• It doesn't require you to decorate your properties with attributes.
• It works with both { get; private set; } and just { get; }.
