Validating JSON Schema in C# - Is there a better method?

Question

Currently I am building some functionality that takes an object (in my case a blog post) in JSON format and validates it meets the 'Post' schema before deserializing it into an object. This is my current solution -

    {

        const string rawPost = @"{
        ""userId"": 1,
        ""id"": 200,
        ""title"": ""hello"",
        ""body"": ""body""
    }";

        JSchemaGenerator generator = new JSchemaGenerator();
        JSchema schema = generator.Generate(typeof(Post));

        var isPost = IsValid(JObject.Parse(rawPost), schema);

        if (isPost)
        {
            var post = JsonConvert.DeserializeObject<Post>(rawPost);

        }

    }
    public static bool IsValid(JObject jObject, JSchema jSchema)
    {
        return jObject.IsValid(jSchema);
    }

    public class Post
    {
        public int userId { get; set; }
        public int id { get; set; }
        public string title { get; set; }
        public string body { get; set; }
    }


}

Currently I do not like the fact that my 'Post' object in this case has incorrectly cased properties and breaks normal conventions - Which means the object is not very reusable. Is there another way of achieving the same thing with Pascal Casing?

You could decorate the properties of your class with the NewtonSoft JsonProperty attribute, setting the PropertyName as follows:

using Newtonsoft.Json;
public class Post
{
    [JsonProperty(PropertyName = "userId")]
    public int UserId { get; set; }
    [JsonProperty(PropertyName = "id ")]
    public int Id { get; set; }
    [JsonProperty(PropertyName = "title ")]
    public string Title { get; set; }
    [JsonProperty(PropertyName = "body ")]
    public string Body { get; set; }
}

The JsonSerializer object will use these in its deserialization.
