如何在 JSON 响应 ASP.NET Core 中关闭或处理 camelCasing

I'm running through a WintellectNOW course on ASP.NET Core/Web API/Angular 2. I have the API portion implemented, but for whatever reason, the JSON that is being returned has the variable names being lowercased.

返回的JSON格式如下.

[
 {"id":1,"name":"Bowler","color":"black","count":1},
 {"id":2,"name":"Fedora","color":"red","count":1},
 {"id":3,"name":"Baseball Cap","color":"blue","count":3}
]

I'm expecting...

[
 {"Id":1,"Name":"Bowler","Color":"black","Count":1},
 {"Id":2,"Name":"Fedora","Color":"red","Count":1},
 {"Id":3,"Name":"Baseball Cap","Color":"blue","Count":3}
]

Based on the C# model of...

namespace HatCollection.Models
{
    public class Hat
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Color { get; set; }
        public int Count { get; set; }
    }
}

I even went as far as decorating the properties with [DataMember(Name = "Id")] just to make sure and it still didn't matter.

在关闭的机会，这是相关的行动和实例变量在控制器...

private static readonly List<Hat> MyHats = new List<Hat>
{
    new Hat {Id = 1, Name = "Bowler", Color = "black", Count = 1 },
    new Hat {Id = 2, Name = "Fedora", Color = "red", Count = 1 },
    new Hat {Id = 3, Name = "Baseball Cap", Color = "blue", Count = 3 }
};

[HttpGet]
public IEnumerable<Hat> Get()
{
    return MyHats;
}

如何关闭camelCase功能，以便ASP.NET Core返回属性名而不更改它们？
