如果class使用了DataContract，name没有使用DataMember的property就不解析
[DataContract]public class File{ ???// excluded from serialization ???// does not have DataMemberAttribute ???public Guid Id { get; set; } ???[DataMember] ???public string Name { get; set; } ???[DataMember] ???public int Size { get; set; }}File file = new File{ ???Id = Guid.NewGuid(), ???Name = "ImportantLegalDocuments.docx", ???Size = 50 * 1024};string json = JsonConvert.SerializeObject(file, Formatting.Indented);Console.WriteLine(json);// {// ??"Name": "ImportantLegalDocuments.docx",// ??"Size": 51200// }DataContract with Json.Net
