c# - Prefix some characters to the property name - JSON Serialization

Question

If I have a class like

class A
{
    public int Age {get; set;}
    public string Name {get; set;}
}

Is there a way to serialize this object to generate properties with some arbitrary characters like this

[{ "prefix.age": 1, "prefix.name": "Apple" }]

I'm using Newtonsoft.Json for my serialization needs.

Answer 1

Just apply the JsonProperty attribute to your class properties like this:

class A
{
    [JsonProperty("prefix.age")]
    public int Age { get; set; }

    [JsonProperty("prefix.name")]
    public string Name { get; set; }
}

And then serialize it:

var a = new A { Age = 1, Name = "Apple" };
var serializedObject = JsonConvert.SerializeObject(a);

serializedObject will contain JSON string: {"prefix.age":1,"prefix.name":"Apple"}.
