如何使用C# - NewtonSoft.Json进行条件序列化

var obj = new YourObject();
obj.Property1 = "Value1";
obj.Property2 = "Value2";

string json = JsonConvert.SerializeObject(obj);

public class YourObject
{
    public string Property1 { get; set; }
    
    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    public string Property2 { get; set; }

    public bool ShouldSerializeProperty2()
    {
        return !string.IsNullOrEmpty(Property2);
    }
}

var settings = new JsonSerializerSettings
{
    DateFormatString = "yyyy-MM-dd",
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};

string json = JsonConvert.SerializeObject(obj, settings);
