如何以符合标准的方式在.NET中序列化DateTime对象

Install-Package Newtonsoft.Json

using Newtonsoft.Json;

DateTime dateTime = DateTime.Now;
string jsonString = JsonConvert.SerializeObject(dateTime);

using System.IO;
using System.Runtime.Serialization.Json;

DateTime dateTime = DateTime.Now;
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(DateTime));
using (MemoryStream ms = new MemoryStream())
{
    serializer.WriteObject(ms, dateTime);
    string jsonString = Encoding.UTF8.GetString(ms.ToArray());
}

using System.Text.Json;

DateTime dateTime = DateTime.Now;
string jsonString = JsonSerializer.Serialize(dateTime);
