使用Newtonsoft.Json序列化具有属性的对象(abc和abcSpecified--设置为false)，并且json字符串中没有abc

using Newtonsoft.Json;

public class MyClass
{
    public string Abc { get; set; }
    public bool AbcSpecified { get; set; }

    [JsonIgnore]
    public string IgnoredProperty { get; set; }
}

public class Program
{
    public static void Main()
    {
        MyClass obj = new MyClass
        {
            Abc = "value",
            AbcSpecified = false,
            IgnoredProperty = "ignored"
        };

        string json = JsonConvert.SerializeObject(obj);
        Console.WriteLine(json);
    }
}

{
    "AbcSpecified": false
}
