仅装饰属性[JsonProperty(NullValueHandling = NullValueHandling.Ignore)]应做您想要的。除非将属性设置为空字符串。
只是想知道，为什么需要DataMemeber属性？
这是工作中的dotnetfiddle的链接
using System;
using Newtonsoft.Json;
using System.ComponentModel;
public class Program
{
public static void Main()
{
var user = new User();
user.UserID = "1234";
user.ssn = "";
var settings = new JsonSerializerSettings();
settings.NullValueHandling = NullValueHandling.Ignore;
settings.DefaultValueHandling = DefaultValueHandling.Ignore;
Console.WriteLine(JsonConvert.SerializeObject(user, settings));
}
}
public class User
{
[DefaultValue("")]
public string UserID { get; set; }
[DefaultValue("")]
public string ssn { get; set; }
[DefaultValue("")]
public string empID { get; set; }
[DefaultValue("")]
public string schemaAgencyName { get; set; }
[DefaultValue("")]
public string givenName { get; set; }
[DefaultValue("")]
public string familyName { get; set; }
[DefaultValue("")]
public string password { get; set; }
}
