How do C# classes deal with dollar signs in JSON?

Question

I'm getting a JSON feed from Google's data API and a lot of the property names start with a $ character (dollar sign).

My problem is that I can't create a C# class with a variable name starting with a dollar sign, it's not allowed by the language. I'm using JSON.NET from Newtonsoft to convert JSON to C# objects. How can I get around this problem?

Answer 1

You could try using the [JsonProperty] attribute to specify the name:

[JsonProperty(PropertyName = "$someName")]
public string SomeName { get; set; }

Answer 2

firas489 was on the right track that $ indicates metadata, not an actual data field. However the fix is actually to do this:

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.MetadataPropertyHandling = MetadataPropertyHandling.Ignore;            

Set the metadata handling to ignore, and then you can serialize/deserialize the property using the PropertyName attribute:

[JsonProperty("$id")]
public string Id { get; set; }
